The Big One Here

What happened last time and what will happen next time.

By Crawford Kilian, 3 Jan 2005, TheTyee.ca

tsunamism

At about 9:00 pm on January 26, 1700, the Cascadia thrust fault broke along a front perhaps 1000 kilometers long.

The fault lies about 100 km west of Vancouver Island, and runs south from B.C. to northern California. It’s the line where the North America plate is gradually overrunning the much smaller Juan de Fuca plate. Normally the plates are locked, but every 500 years or so the pressure overwhelms the resistance of the rock. With every such “subduction” quake, a little more of Juan de Fuca sinks beneath the larger plate.

The 1700 Cascadia quake, like the one off Sumatra on December 26, released enormous energy. Some of it went into raising or sinking shorelines on the coast of Vancouver Island and Washington; some of it went into a tsunami that crossed the Pacific in a few hours and inflicted damage on the Japanese coast. Detailed Japanese records of that event enabled geophysicists to pinpoint the time of the Cascadia quake.

That quake had an estimated “moment magnitude” of 9, like the Sumatra quake, and it was a bit smaller than two of the worst quakes of the 20th century: a 1960 quake in southern Chile measured 9.5, and the Good Friday Alaska quake of 1964 measured 9.2.

The impact of Cascadia is recorded in Japan and also in First Nations accounts and coastal geology. Peoples of Vancouver Island tell about a quake that occurred at night and waves that wiped out villages and their inhabitants, except for the fortunate few who could reach high ground. Tidal marshes on Vancouver Island’s west coast have layers of tsunami-driven sand overlying layers of peat.

A choice of disasters

Subduction quakes appear to hit B.C., on average, about every 500 years. But the actual gap may be much shorter or much longer. In the intervals, “crustal” quakes occur within the North America plate. “Subcrustal” quakes occur deep within the buried Juan de Fuca plate.

Such quakes shake the region less violently but more often. John J. Clague, a geologist at SFU, says that on average we get a magnitude 7 quake every 40 or 50 years, a 6 every 20 years, and a 5 every 5 years.

B.C.’s last sizable earthquake was the 1946 Courtenay quake, a 7.3. Two very large quakes, possibly subduction events, occurred around 300 AD and 1500 B.C.; the older one, says Clague, may have caused southern Vancouver Island to subside while raising the Vancouver area by “tens of centimeters.”

The 1700 Cascadia event and earlier earthquakes affected scattered populations of no more than a few thousand. Over 2.5 million people now live in southwestern B.C., many in especially hazardous areas like the Fraser delta. Clague warns that in B.C. today a similar subduction quake, or even a modest magnitude 7.5, would cause damage estimated at between $17 billion and $40 billion.

When it happens to us

We have a fair idea of what happened in 1700, and if we assume a close repetition of the Cascadia quake in the near future we can predict what the effects would be, and where.

The greatest hazard would come from ground shaking. A strong crustal quake close to Vancouver, Clague says, would inflict about 30 seconds of violent shaking; a magnitude 9 subduction quake would shake the region for one to three minutes. With an epicenter off Vancouver Island, that might mean less damage in the Lower Mainland, or it might mean more.

Earthquake waves go quickly through solid rock. But they slow down in sand and gravel—enough to liquefy the soil, destroying its bearing capacity. The Fraser delta consists of over 200 meters of water-saturated clays, sand and gravel. In a modern magnitude 9 quake, the Fraser delta and floodplain would lose their ability to support heavy structures. The delta alone is now home to 200,000 people. Other deltas, landfills and shorelines would also liquefy. High-rise buildings on such soils would probably collapse.

In 1946, the Courtenay quake triggered over 300 landslides. Caused partly by liquefaction and partly by ground shaking, slides from a magnitude 9 quake would cover, Clague says, 500,000 square kilometers. That would include all of southern Vancouver Island, northwest Washington State, the Gulf Islands, and southwest B.C..

Between ground shaking, liquefaction, and landslides, Vancouver and Victoria would be cut off from the rest of the world. Highways and railroads would be cut. Bridges would fall. Docks would be unusable, whether sunken into landfill or simply knocked down. B.C. Ferries terminals, the Roberts Bank coal terminal, and Vancouver harbour would all be crippled. Vancouver International Airport might be under water, or so broken up as to be usable only by helicopters. Even if it survived intact, the roads and bridges serving it might be wrecked.

Power lines would probably be down. Water supplies from Coquitlam and the North Shore might survive but would almost surely be contaminated by landslides in the watersheds. Fires breaking out in collapsed buildings would be hard to fight, and hospitals would be as overwhelmed as those in Thailand and Sri Lanka.

Government agencies could be paralyzed by disrupted transport and communications, not to mention the deaths of many personnel. The nearest source of help would be Seattle, probably as damaged as ourselves.

Spared from tsunamis

And what about tsunamis? Clague offers some consolation on that score: while tsunamis would certainly smash the west coast of Vancouver Island, the central coast, and the Queen Charlottes, they would lose energy as they came through Juan de Fuca Strait. The ruined shorelines of Vancouver might be flooded, but by subsidence rather than tsunamis.

In fact, Clague notes, when a crustal quake lifted parts of Seattle by 7 meters a thousand years ago, it caused a severe tsunami in Puget Sound—but not in the Strait of Georgia. The greatest damage from a Cascadia tsunami could again be inflicted on Japan.

Clague sees a crustal quake as more likely to hit us before a subduction quake does. For every magnitude 8 or 9 event, the Pacific Northwest gets about 50 quakes of 6 or 7. He cites the 1994 Northridge quake in California. A 6.7, it caused over $15 billion in damage.

Aftershocks

So we could suffer enormous damage and loss of life from a crustal quake, only to recognize the continuing threat from a still larger subduction quake. Rebuilding our cities would involve a far higher level of earthquake resistance than we now have, and we could not risk spreading the cost over a decade or more, as we have been doing with school-building upgrades.

Private investment might be slow to arrive when the costs would be so high and the chance of further losses seemed so much greater. Governments would have to draw higher taxes from a weaker economy, just to get us back to today’s living standards.

The Sumatra quake did teach our governments one important lesson: The plight of the victims mattered enormously to people all over the world. Ottawa and Washington, after a feeble first response, realized that public concern has a magnitude of at least 9 on the political scale. Efforts to help the victims in South Asia will continue, but it should also now be politically possible to invest in the necessary infrastructure and emergency planning for B.C.’s vulnerable communities.

We responded to South Asia because we could imagine ourselves in the victims’ place. Some day, inevitably, we will be victims too.

Regular Tyee contributor Crawford Kilian recently re-read his 1983 novel Tsunami and found the descriptions depressingly accurate.  [Tyee]

    Dusted of a copy of an old book and read Francis Shepard's first hand account of account of tsunami in Hawaii, 1946 (found an internet copy at http://www-class.unl.edu/geol101i/tsunami.htm ) Unfortunately it does not have the additional text of my 1972 issue of Reader’s Digest “Marvels and Mysteries of The World Around Us” Here is some of it: “Today there are tidal-wave alerts when reports of earthquakes indicate dangerous possibilities, or when early waves arrive at other islands along the general route, or when the tide begins to fluctuate in an abnormal fashion. These warnings are important. Most of the 159 people who were lost during the 1946 tsunami could have been saved if they had run to higher ground when the waves first began. ...Almost everyone was conscious of a sudden diminution of the noise of the breakers when the sea withdrew. Most people ran to see the strange site of the reefs being laid bare, and many went out on the reefs to pick up stranded fish. The 1957 and 1960 tsunamis were almost as destructive to property in Hawaii as that of 1946, but thanks to the warning system no lives were lost in either instance…. Investigations that followed the 1946 tsunami resulted in some conclusions that should prove helpful in lessening the damage done by future calamities of this sort. The increasing height of the successive waves was perhaps the most important lesson.” Just listening to the Current on CBC AM Jan3 and heard that officials in Hawaii heard their tsunami alarms go off and tried calling the official numbers to warn South Asian countries. It was Sunday and no one answered! So, for the poor souls in that part of the world: No Education, No Warning, Not even half heated bureaucratic Tsunami Emergency Plans. Are they still third world countries? Or is it our civilization that is so forgetful and fallible? Maybe we deserve to go the way of the Romans.

    As a parent of two children who attend one of Vancouver's many seismically "high-risk" public schools, I am very worried. Gordon Campbell's recent promise of a 15-year plan to upgrade schools comes only months before he faces an election. It was his government that scrapped the seismic mitigation program that was upgrading schools, and his govenment that has dramatically reduced annual ministry of education capital budgets that fund seismic upgrades. Interestingly, provincial jails and liquor distribution branches have been upgraded. I guess that tells us something about this government's priorities. Thousands of kids could be injured or killed, but the prisoners and booze are safe. This is really disgraceful.

    Only by electing at least one MLA, that is a seismologist or geologist will I feel safer from an EARTHQUAKE. If there was at least one MLA that is a climatologist will I feel that some action is being taken on GLOBAL-WARMING. If there is one MLA that is a virologist/ biologist will I believe that some action is being taken to prepare B.C. for a FLU-PANDEMIC... I have not seen any evidence to suggest that a seismologist, a climatologist, a virologist, or any other scientist will become an elected MLA in May/2005. Until these conditions are met I feel like "Scared" in the above e-mail.

    I'll be paying attention to my dog's behaviour, I can tell you that much. In Taiwan on Sept 21,1999 he was acting strange all day, really quiet and just staring at me. I was starting to worry he was sick or something... that night Taiwan was hit by a 7.6 and over 2,000 died. If people can't get their act together let's at least pay attention to our animals with their fine-tuned sixth sense.

    Crawford's article is excellent. I share Patti's concerns regarding the disgraceful record of the Campbell government with regard to the much needed seismic upgrading of our schools. For the information of "Scared Ranbir", I am a geologist living in the liquefaction-susceptible Fraser Delta (Ladner), and I am seeking the NDP nomination to contest the next provincial election in the riding of Delta South. I hope to be that geologist MLA he wishes to see elected in May!

    Ranbir how do you know there aren't scientists running etc? Have you read all the bios? What does it matter? One MLA can do nothing (look at the Leg right now) what we need is a Premier and a cabinet that will listen and prepare-we'll get that with carole James and Co. (especially with me around to bug them!). If you live in Central Saanich (or anywhere on the peninsula) note that there will be an emeregency preparedness meeting Jan 27 at Central Saanich Municipal Hall-watch for posters or email me

    Besides all this remember that you will have to be responsible for yourselves for at least the first 72 hrs - do you have an emergency kit supplied to do that? Have you a neighbourhood plan (if not contact the Provincial Emergency Program for info on how to get one set up). No need to be sleepless on our coastline if you do what needs to be done--waiting for someone else isn't the answer.

    I have not read all the bios, but I have read alot of bios and sadly scientific ability is very rare among elected-representatives. I am pleased to read that Dileep Athaide is a "geologist." Any virologist, climatologists, ecologists, chemists, biologists running??? Scientific-ability "matters" very much! It takes TIME to develop scientific-ability. Scientific facts are "truths" that have been verified by experiments and tests. It is only logical to base public-policy/laws on scientific facts. Previous generations of scientifically-illiterate elected-representatives have caused GLOBAL-WARMING and other serious long-term environmental problems that we have today.

    Previous MLAs have also created the ALR which saved much of our rare arable land for agriculture; Harcourt's government gave us the 12% parks the Bruntland Commission recommended (not nearly enough in my book, but a start) and a good forestry code (now gutted) a UN-praised labour code (now destroyed) and much much more. Stop looking for someone else to fix things. Do it yourself. Run! Join a party! Make resolutions! Read the policies of the NDP (and others)! Note that when in government the NDP makes great use of the expertise of scientists etc. One of the things we were very good at was drawing in all stakeholders and letting them have a say too - sadly small business and others fell for the BIG LIE that we did not do that and now look what they've got-funny how looking for the pot at the end of the rainbow often causes you to stumble over the gold mine at your feet! Where did I say that scientific ability does not matter? Nowhere. One of the great failings of our democracy is that citizens DO NOT LISTEN in this case read, carefully enough and jump to conclusions. As a result they write off good ideas and fall for baloney. By the way there were MANY scientists in those "previous generations of...elected representatives" and yes they did fail to stop global warming. Read some more about who was in power my friend. Being a scientist does not make one morally superior or there wouldn't be so many scientists working for tobacco companies, big pharmceuticals, Adolf Hitler, George Bush etc. You have to scrutinize the scientists as carefully as any body else! After all the greatest scientists of the age gave us our nuclear nightmare and only a very few of them denounced it. Science is now panacea. Logic, a good heart, a sense of justice and basic honesty are better measures. Science is only a tool and can be used either well or foolishly (that's why California has nuclear reactors in high tsunami danger zones!). Cheers

    Mr. Kilian. Regarding the 1700 Cascadia tsunami. We own some acrage on the West Coast of Vancouver Island near Port Renfrew in the middle of the San Juan River delta 3 kms from the ocean. While digging with a backhoe I've found a layer of very well preserved green vegetation several feet down. I know when I've hit this layer due to the instant sulpherous smell that fills the air. I thought that this buried "field" was due to a previous river flood but perhaps this grass was buried by the 1700 tsunami. Where would I find out more information about other sites of tsunami buried vegetation on the west coast of the Island? PS- I did some calculations. If (when) the "big one" hits 100 kilometers west of Port Renfrew and the resulting tsunami travels at 800 kph, then I would have about 7.5 minutes to load the cats, dogs, lifejackets and family in the truck, drive 3 kilometers towards the ocean and then a kilometer along the beach in order to reach high ground. Hopefully we'll be in Victoria buying groceries when it hits. Thanks for the informative article.

    Like Patti and thousands of other B.C. parents, I worry many mornings when I drop my child at our 100-year old Vancouver school, knowing it will collapse in a moderate/severe quake. Parents at our school, like many others, have repeatedly written Premiers, Opposition leaders, MLAs, MPs and local media for years, urging them to act..... In 2001, campaigning MLAs promised us this would be a priority, but then did nothing except cancel the existing school seismic mitigation program. Campaigning federal MPs promised the same last year but have done nothing since heading to Ottawa as Cabinet Ministers. Finally responding to the efforts of Families for School Seismic Safety and Dr Tracy Monk, our Premier has promised to speed up school seismic upgrading after the next election & to complete the job in 15 years..... Meanwhile, Seattle has almost finished fixing their schools and B.C. has committed billions to complete Olympic facilities, Whistler highway & RAV over 6 - 8 years. The Premier's announcement is a good start--more than others have done to date--but it's still far too little and far too slow, given the lives at stake: at least 200,000 B.C. children in at-risk schools. The risks facing hundreds of thousands of families in Richmond, Delta and other vulnerable areas are no less frightening.... We can never eliminate risk or totally control nature, but we can certainly mitigate impact and save lives if we don't bury our heads in the sand and we're prepared to pay the costs. How heartbreaking that so many had to die in Asia to remind us of the terrible and far higher costs of failing to do so. Please, let's not allow this to become a political football, but pull together to ensure it gets taken seriously and addressed quickly by whoever is in office in Victoria and Ottawa. When our children and our neighbours are gone, no amount of donations, tears, guilt or recrimination will ever bring them back.

    Sue Stroud: Although you seem to think that the "Provincial Emergency Program" (PEP) will help you in a 9.2 earthquake, you may want to look into the "laws" of the program. I lost my home north of Squamish in the fall of 2003, I had not evacuated as I had farm animals to care for. When I was able to hike into town three days after the flood (PEP) would not assist me as I did not "evacuate", meanwhile they were putting up squatters and people that lived in tents! I practically had to beg before they would help. And when it came to assisting with my home, they were so stingy I could not afford to rebuild, and sold for land value only. From experience, my suggestion is to be as self reliant as possible, have an emergency kit prepared, water, canned food, and a first aid kit. If you think this government isn't helping you now, don't think they will in a disaster!!!

    I used to work in a certain Vancouver high school and staff were told that sections of the building would definitely "pancake down" on top of us when we have a quake of a certain magnitude. That would mean about 1,000 people killed or injured.

  • allan (not verified)

    Ranbir, I share your concerns that science really doesn't get the play it should from politicians. It is encouraging that Dileep Athaide, a geologist, is planning to run for the NDP in Delta South. One has to assume he would have a better grasp of the needs of his own constituents should the need ever arrive, than say some flight instructor who's skills appear to be centred around the ability to outrun embarrassing political events. But, as several writers have noted here, we have other real big issues that need addressing now (like global warming), but the world's top scientists appear to be getting nowhere convincing politicians to take their fears seriously. The problem for scientists who want to be politicians is in the making of promises. The scientist will review an issue and look for a solution. If there isn't one, it's assumed the scientist will say so. We all want honesty, but to many voters a used-car salesman with a can-do attitude, based on nothing more than bravado and a potential commission, has a much more saleable product. Issue all the caveat emptors you wish, but until voters realize we can't buy ourselves out of every problem, we'll unfortunately continue picking the brightest looking lemons with the most bitter of seeds.

    Steveoverhere, are you saying you resent the donations and help being sent to South Asia? Are you saying an area with a population of over a billion is nothing more than extremists who hate us all? I would suggest some travel in the future. You could even try making some friends from another culture. It's not so scary.

  • Steveoverhere (not verified)

    No, not at all, what I find ironic is that all the billions of dollars being poured into the area that is well known for fostering extremism toward the west. The same people who blow up buildings killing tourists ( Indonesia) and who have spent the last 20 years killing each other and mining everything in sight are now holding out their hands to the wealthly west for assistance. I have nothing against helping innocent people but there is a certain irony here. And by the way, I have travelled quite a bit and have a large number of friends from other cultures. Some of which are our own who could sure use some of those funds we are so quick to throw to other countries. Been down to the eastside of Vancouver lately, or downtown Prince George?

    EASY to be negative! Armchair critic. What do suggest? Give up and allow these people a slow death? The percentage of extremists in a population of millions is low yet you condemn a nation on the actions of a few. By the way we do help our own. Our poorest still have a higher standard of living than these people. We have choice.......and the opportunity to attain a better standard of living if we are willing to be think out of the box and get off our butts.

  • Fi (not verified)

    Well, I'm going to play devil's advocate here and argue that "our poorest" do NOT have a higher standard of living than "these people". In what way do they? Atleast "those people" have a sense of community that we can't even begin to comprehend. If one has no home, an empty stomach and barriers to health care, whether you are in Canada or Thailand- your standard of living is bottom line. Steveoverhere has valid points. Maybe that's why we are able to ignore our own poor so guiltlessly; we convince ourselves that "Well, hell, they are in Canada, that alone gives them a certain 'standard of living.'"

  • allan (not verified)

    7 years ago

    Fi, you certainly are right that an empty stomach is a true equalizer. I also prefer your take on why we don't want to offer much compassion to our own poor over Get Going's cavalier inferral that our poor are simply not creative enough and or too lazy to help themselves. He sounds like a new era Liberal with a bootstrap puller for rent. But Steveoverhere takes the Marie Antoinette cake with his "Muslim extremists" comments and rants against the entire world that hates us all here in our first world wealth. To expect that third world or even poorer nations to respond in kind to a disaster here in North America is a bit much. At this point in history the west has the money, yet poorer countries could always help us out by exporting some of that "sense of community," which Fi mentioned above and which we in our laptop world have lost. It doesn't excuse our niggardly treatment of our own poor, but then describing entire nations as terrorists suggests Steveoverhere also brought a certain amount of preconceived bias into this discussion. That said, however, Steveoverhere's mention of downtown Prince George shouldn't be ignored. Perhaps if Prince George could import some third world "sense of community" some of it might drift downtown to city hall. That's where the decision to allow developers to build big box stores outside the core retail area was the final nail in the downtown's cofin.

    The schools constructed by the City of South Vancouver before amalgamation into the present City of Vancouver are woefully inadequate if there is a large quake today. These school, all alike in looks (Sexsmith, Van Horne, Wolfe, etc.) were built during the depression with depression budgets and many corners were cut in their construction such as not binding the rafters to the ceiling joists to save costs. Many upgrades have covered this problem for most schools. The outer walls were secured by rods to prevent the buildings from pancaking in event of the roof collapsing. Another problem is the brick claddings of the schools which are in danger of peeling because the metal straps holding the bricks to the walls have deteriorated and will probably no longer hold in a really bad quake. The bricks probably would be falling as the children were evacuating the school. There is also a the question of the slate shingles on the steeply pitched roofs, will they hold in a severe quake? How do the teachers and children exit the school with debris falling from the walls and roofs? The concrete foundations of most of these schools are also a question mark as much of it was laid on bare ground with no vapour shield to keep moisture from entering the brickwork and the concrete itself. These schools were constructed as a shell and rooms added as the population of the area grew. In many cases these buildings would be better torn down and replaced. Probably the oldest group of at-risk buildings in the Province are our schools and they should have been upgraded or replaced. I wonder which Government will be in power when the quake happens and which 'past' one they will attempt to blame? The professional excuse writers will help elected officials cover their collective butts amidst much hand wringing. Trouble is the present bunch have the ability to fix the problem now but they are definitely dragging their feet on a proper solution. Notice that the Legislature itself has been upgraded. So just who do our politicians think are more important, children or themselves?

    A letter I must admit I sent to the Vancouver Sun (and was published there Wednesday Jan 19): For more years than I care to remember, I've had a recurring dream: I am somewhere along English Bay, often in the West End but sometimes at Ambleside or across the bay at Jericho, and I feel or hear a rumbling. I look toward the west, toward where I would normally see Vancouver Island, but instead, there is a huge, foaming green wall of water racing toward me. Since there is no practical way we can defend our coastal areas against a large tsunami, not by dikes (how high would you make them?) or diversionary channels, then we must face the fact that sooner or later our communities will be hit by something larger than we can handle. Common sense might say, don't build close to the water or on land level with or even below the tideline, but we place a high value on land with an ocean front view or, better yet, access. Believe me, dream or not, if I had the money, I would have a place on the water instead of a two-bedroom apartment on Broadway. So it comes down to what measures are in place to warn, evacuate and deal with the aftermath of a tidal calamity, or an earthquake that wreaks havoc in Vancouver or Victoria. And how much do we want to spend on such preparations given that we have no idea when they might occur? It's a bit like those bomb shelters some people built in the 1960s and the "duck and cover" instructions some children got in schools (as if that would have done anything). I know there's a good chance of an earthquake here, but do I have an earthquake survival kit in the apartment? I could probably dig out a flashlight, a bottle or two of water, some cat food and that's about it. Will I put together a kit? Will you? Even after our awareness is re-awakened by a tragedy elsewhere, we are a head-in-the-sand people who would rather spend our money on "sure" things even though every living geoscientist says a large magnitude quake, or tsunami, or even a volcanic eruption, is just as likely to happen tomorrow as 50 or 100 years from now. In my recurring dream, the wall of green water roars toward me. I turn to run, but there is nowhere to go.

    Steveoverhere; I just noticed your response to my criticism and especially that line about "countries that export fear" etc. Why are you picking on the Americans like that? Also, could you explain that "pisspot" thing once again. Sorry, but I was under the impression our Liberal government had recently sold it off even though it had been working quite well since 1991 when Bill VanderZalm's (sorry, Rita was asked to flush and turn off the lights, wasn't she), rusty bucket was kicked into the gutter. Give at home first, you say? We already have. We gave away BC Rail, BC Ferries, our medical services files, control of our oil and gas, most of our forest reserves. We've been more generous than you realize my friend.

    Government (no matter which stripe) brings no particular talent to running anything. As a matter of fact, by definition, government cannot run anything properly. While private industry does have their problems, I think it is far and away the lesser of 2 evils in almost anything. When you are 4 feet under and digging fast, the most important thing is to stop digging first. As far as the pisspot, I think we have bought it back from Ottawa, where the previous administration took it when they went begging for a handout.
