Five years ago I wrote a long series of posts about the Indian Ocean earthquake and tsunami, compiling information from around the Web and using my training in marine biology and oceanography to help explain what happened. Nearly 230,000 people died in that event.
Tuesday's magnitude-7 quake in Haiti looks to be a catastrophe of similar scale. I first learned of it through Twitter, which seems to be a key breaking-news technology now. Hearing that it was 7.0 on the Richter scale and was centred on land, only 25 kilometres from Port-au-Prince, I immediately thought, "Oh man, this is bad."
And it is. Some 50,000 are dead already, and more will die among the hundreds of thousands injured or missing. Haiti is, of course, one of the world's poorest countries, which makes things worse. Learning from aid efforts around the Indian Ocean in 2005 and from other disasters, the Canadian government is offering to match donations from Canadians for relief in Haiti.
This is a reminder that we live on a shifting, active planet, one with no opinions or cares about us creatures who cling like a film on its thin surface. We have learned, recently, to forecast weather, and to know where dangers from earthquakes, volcanoes, floods, storms, and other natural risks might lie. But we cannot predict them precisely, and some of the places people most like to live—flat river valleys, rich volcanic soils, fault-riddled landscapes, monsoon coastlines, tornado-prone plains, steep hillsides—are also dangerous.
Worse yet, the danger may not express itself over one or two or three human lifetimes. My city of Vancouver is in an earthquake zone, and also sits not far from at least a couple of substantial volcanoes. Yet it has been a city for less than 125 years. Quakes and eruptions happen in this region all the time—on a geological timescale. That still means that there has been no large earthquake or volcanic activity here since before Europeans arrived.
We would, I hope, do better than Port-au-Prince in a similar earthquake, but such chaos is not purely a problem of the developing world. The Earth, nature, and the Universe don't take any of our needs into account (no matter what foolishness people like Pat Robertson might say). We are at risk all over the world, and when the worst happens, we need to help each other.
