M3.5 aftershock to Duncan earthquake

There was an additional >M3 aftershock on Sunday morning that was not in my previous posts (see orange dot at right).  The main M5.3 event was at about 10 pm on Saturday.

Note that we have upped the magnitude to 5.3 from the initial 5.2.    I'll provide details on that later.

AZGS has recorded a larger number of small aftershocks on our statewide seismic network that we are determining locations for.
