I feel the earth move under my feet

What's been the most seismologically active part of the world this week?

That's right, the Kuril Islands, with an impressive 45 earthquakes of magnitude 5 or above since Sunday.

The largest (8.3) even made the CNN news, with a major tsunami warning. The wave turned out to be only 40cm high, but I guess the evacuations were a necessary precaution.

How do I know all this? Because I get notification of all the world's earthquakes, direct from the US Geological Survey. And you can too, if you fit the same Firefox extension, available here. The browser window wobbles every time there's an earthquake somewhere in the world.

If that doesn't shake you out of using Internet Explorer, surely nothing will.
