Description: From McGimsey and others (2008): "On September 13, 2005, a long sequence of strong seismicity was recorded on the newly operational Korovin seismic network. The sequence began with two small local events followed by about 30 minutes of weak tremor, and then about 20 weak local events. Nothing unusual was detected on satellite images of the time period.

"Although a network of seismic stations was installed on northern Atka Island during the summer of 2004, data were not accessible until early March 2005, and Korovin was not considered to be seismically monitored until late 2005 - announced in the December 2, 2005, Information Release - when a sufficient period of background seismicity had been recorded, and equipment/communications problems resolved (see table 1 in original text). On December 2, Korovin, which previously had been listed as UA, was formally assigned Color Code Green."
