Very short--but I don't see any links yet so will fill you in with a couple of links.
2 shallow earthquakes of mag. 6.3 and 6.4 have hit NW Iran--depth of about 9-10km. (UPDATE: 80 deaths) have been confirmed so far.
Epicenter is 12 miles from Ahar and 37 miles from Tabriz.
The Bam earthquake measured a 6.6--so at least in terms of magnitude this is in a similar range.

I won't be able to do updates today, but consider it an open thread to monitor things, if no one else posted a more informative diary.
