Perspective, Please?

Reading about the US decision to evacuate people out of Japan makes me roll my eyes. I can maybe see where people in Tokyo -- a mere 200 miles away from the problem may think that's a little too close for comfort. But Nagoya? It's 400 miles away from the Fukushima plant. That's like saying there's a problem in San Francisco, so let's evacuate everything between here and LA. Or actually, a more appropriate analogy would be that someone conducts nuclear tests in the Nevada desert, so let's evacuate Oakland. Seriously. It's a long distance, the winds don't blow that way, and there's a whole lot of mountain ranges in between.

As with any crisis, there is a lot of confusing and conflicting information. Don't take everything you read as a sign that the world is ending.

Random Geological Geekery

USGS lists that half an hour after the initial 9.0 shock there was a 7.9 'quake, followed ten minutes later by a 7.1. I'm wondering if the two large shocks so soon after the initial one contributed to the severity of the tsunami?

The frequency and severity of the aftershocks is coming down. But I bet folks in the area will be very glad once the ground Knocks It Off.
