Seismicity of Azerbaijan

I'll be away in Azerbaijan the next three weeks or so, working at the Oglanqala archaeological site doing magnetometry.

The Azerbaijani National Academy of Sciences Geology Institute says:

Genetically seismicity of Azerbaijan is associated with activity of seismogenic structures in the Lesser Caucasus and in the Greater Caucasus Ridges. In the most territory of Azerbaijan earthquakes of magnitude M=6-6.5 may take place and in some seismogenic structures one can expect seismic events of a maximum magnitude up to M=7. This indicates that on the whole the territory of Azerbaijan and the adjacent part of the Caspian depression have a moderate seismicity. Though for the recent period in the Caucasus region there have not been recorded any seismic events of magnitude M>7-7.2, from the point of view of their peculiar features this region is characterized by a high engineering-geologic risk. This distinguishes the territory of Azerbaijan from the Pacific mobile belt where intensity of earthquakes by Richter's scale is M=8-8.5. 

The English isn't the best, but try learning Azerbaijani!

I'll be in the bottom left area of the map, not far from Ararat.

See you in July.

New Jersey quake

Video report on Dillsburg earthquake

From York Fox News 43:

 

Dillsburg, PA, magnitude 2.9

Dillsburg area shaken by another earthquake

CARL LINDQUIST -- The York Dispatch

Updated: 06/03/2010 10:12:24 AM EDT

An earthquake measuring 2.9 on the Richter Scale struck Northern York County on Thursday morning.

The U.S. Geological Survey reported the earthquake hit the area at 8:25 a.m. Thursday. The Geological Survey said the earthquake was about 3 miles from Wellsville and 4 miles from Dillsburg.

The earthquake that struck Thursday matched the strength of the strongest previous earthquake to hit the area. It occurred in April 2009.

Local geologist Jeri Jones said several people called him Thursday morning to report an earthquake.

One caller told him pictures were knocked off the wall of her home, he said. Another caller said a relative in Mechanicsburg also felt shaking.

York County 911 also reported people calling to report an earthquake. No injuries or damage was reported.

The quake that hit Thursday continues the seismic activity reported in the Dillsburg area, which has been rattled by hundreds of distinct tremors since October 2008. Jones said the last major seismic activity occurred on Oct. 25, when the U.S. Geological Survey reported a series of earthquakes with magnitudes of 1.8, 2.6 and 2.8.
