Now it's Alaska

At about 5:32 pm local time on 4-30-08, about 48 miles Nouth of Kanaga Island, Alaska, a 5.1 earthquake occurred. Not out of the ordinary for the area.

23 hours later a 6.1 earthquake hit about 12 miles North of the same island, and about 12 miles West of the Bobrof volcano. Could be a coincidence.

From that time forward to now (10 pm local time of 5-1-08), there has been a series of earquakes ranging from 1 to 4 within a 10 mile wide North-South corridor stretching from 12 miles South to just under 20 miles North of Kanaga island to the West of Bobrof. Could be regular aftershocks from 6.1 quake.

Probably nothing of note here except an interesting quake-storm, especially since these quakes are fairly dispersed, are away from the volcano, and range in depth from about 90 km to surface. Considering that and adding onto it the fact that the quakes hit deep, then shallow then deep again, I seriously doubt there is any magma or any other hot rocks on the move.

I'll keep an eye on this area, too, just to see if anything interesting is happening. Maybe we'll find out if Bobrof is Holocene or not.

I haven't been watching this as closely as I should have been. It seems like it just keeps rumbling. Maybe this is normal for this particular area. I didn't think it was anything weird anyway - just pointing it out. Another reason not to fish the Bering Sea...
