NORTH VANCOUVER (CUP) — With the recent earthquakes on the West Coast and superstorms in the east, the world is starting to look like the set of an apocalyptic Steven Spielberg movie. While climate change may be one of the major culprits behind the increase of hurricanes and tropical storms, it has no effect on earthquakes and volcanoes, or disasters made by the earth rather than the atmosphere.
Even though hurricanes are unrelated to earthquakes, and Vancouver’s potential for natural disasters is totally different than New York’s, witnessing disaster in another urban centre can be alarming nonetheless. If such a big, powerful city that personifies modern urbanity can be the site of such ruin, how might the rest of the world look when the plates are shifting under our feet? Taken together with the recent coastal earthquakes, these catastrophes have people wondering what the cause is, if they’ll become more frequent, and how they might change what our urban futures look like.
Monitoring earthquakes proves to be much more difficult than monitoring storm systems and hurricanes. Because of how the guts of the earth move and shift to cause the earthquakes, science has yet to find a way to successfully predict the phenomenon.
“Climate change, hurricanes… earthquakes, and volcanoes are energized by different sources. So the climate [and] things like hurricanes, all that has to do ultimately with energy that comes from the sun,” explains Michael Bostock, a professor and earthquake seismologist at UBC. “Earthquakes and volcanoes are generated through energy that come from deep in the earth that basically is the residual heat from Earth’s early formation.”
Climate change has nothing to do with the movement of the earth or the shifting of the plate tectonics that cause the earthquakes. And because the shifting happens under the earth’s surface, it makes it difficult for scientists to know what’s happening, and to warn people about potential earthquakes.
“At the present time, the best we can do is forecast. There is a difference between prediction and forecasting. Forecasting is sort of a longer-term thing and we can use our knowledge of seismicity in the past to say something about how likely the occurrence of earthquakes is going to be into the future.
“But predicting things into the daily or weekly basis is going to be very difficult. And the main reason is that it’s very hard to. Unlike the atmosphere, which we can probe easily with satellites … which allows us to predict weather a week in advance, the earth is much harder to penetrate for obvious reasons … So the prospect for being able to predict earthquakes, at least in the short term, is not very good.”
Not being able to effectively predict earthquakes can be detrimental to a community, as seen recently with the 7.7 earthquake that shook Haida Gwaii, B.C. in October.
“There was no warning before the quake hit,” says Cherie Kalhofer, who lives in nearby Masset. “It was kind of wild – it felt like the room was swaying around, just like the plates below us in the ocean below us are said to do during an earthquake.”
