Shake, rattle and roll

That little yellow dot is the epicentre of an earthquake that shook the island Tuesday morning.  No damage done, but a friendly reminder that we live in an active region of mountain building and land creation.  In fact that large island just to the west of us, Vancouver Island, is moving every steadily towards us.  It is part of what is called the Insular Superterrane, a region of tectonic plates that is slowly crashing into the edge of western North America.  In a few million years, Bowen Island will sit in a valley not unlike the current Okanagan.  We'll probably have nice dry weather and our descendants will be growing grapes and mangoes.

And as it creeps ever closer, The Insular Superterrane occasionally lurches a little and gives us a shudder.  In fact we're expecting the stormy geological weather to continue with light showers of tremors and aftershocks during a current swarm.  And who knows, perhaps the Big One will show up as well.  You can never tell, nor guess when it will happen, but it's a fool who doesn't expect it.
