PAGER - M 5.7 - KURIL ISLANDS
Alert Version: 4Tuesday, October 13th, 2009 at 10:15:14 UTCLocation: 44.6° N, 149.1° EDepth: 46kmEvent Id: US2009MSBECreated: 2 days, 10 hours after earthquake.
Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake resistant construction. A magnitude 6.2 earthquake 390 km Southwest of this one struck Hokkaido, Japan (Aftershock) on January 18, 2005 (UTC), with estimated population exposures of 6,000 at intensity VIII and 252,000 at intensity VII, with no reported fatalities. On October 04, 1994 (UTC), a magnitude 8.3 earthquake 167 km Southwest of this one struck , with estimated population exposures of 2,000 at intensity VIII and 39,000 at intensity VII, resulting in an estimated 11 fatalities. Recent earthquakes in this area have caused landslides that may have contributed to losses.

PAGER results are generally available on the Internet within 30 minutes of the earthquake’s occurrence. However, information on the extent of shaking will be uncertain in the minutes and hours following and earthquake and typically improves as additional sensor data and reported intensities are acquired and incorporated into models of the earthquake's source. Users of PAGER estimates should account for uncertainty and always seek the most current PAGER release for any earthquake.
