Alaska earthquake M6.2

This was 102 km deep, and the PGV must have been less than 2 cm/s, although the report isn't in yet.

Very nice tectonics, but get this.

The thing was mostly strike-slip with a bit of subduction thrust.  Very weird, and means absolutely nothing.  Can't wait to see the PGV's and see the soil amplification.

Update:  Reference.   Ok, if your office looks like this after such a teeny, deep quake, get out of town!

Update:  At this point, I only see 2 records of about 6 cm/s on PGV.  The last earthquake of this size showed a general amplification of 5 times between rock and soil.
