Duncan area hit by four larger aftershocks

Arizona Geology Blog - Fri, 2014-07-11 08:54
The Duncan area experienced four more aftershocks in an 18 hour period  [right. credit USGS], with local residents reporting feeling them.   There was a M3.6 event at about 3 p.m. Thursday and a M3.2 at 11:15 p.m.   A M2.8 occurred at 1:38 a.m. this morning, followed by a M3.5 quake at 5:41 a.m. The Arizona Geological Survey is developing an interactive online map viewer to show all the aftershocks we are recording.    We installed 5 portable seismometers around the main shock epicenter area earlier this week which should be accurately recording not only these larger events but many other shocks that are too small to be felt.   
The Duncan M5.2 main shock hit on Saturday, June 28.

Temporary seismic stations capturing more aftershocks to Duncan earthquake

Arizona Geology Blog - Wed, 2014-07-09 08:27
AZGS staff installed three more temporary seismometers yesterday, in the area around the M5.3 Duncan earthquake in eastern Arizona.  This brings the number of temporary stations to five.   AZGS geologists Jeri Young and Mike Conway observed half a dozen micro-quakes roll across the area just during lunch while they were installing the stations.     Mike posted details and photos at our Facebook page.  [Right, Jeri Young setting up temporary station]

At 1:15 a.m. this morning the area experienced a M3.6 aftershock which should have been captured by the new stations.     [Left, orange star marks aftershock epicenter.  Credit, USGS]
