PAGER - M 7.0 - JAVA, INDONESIA

Alert Version: 4Wednesday, September 2nd, 2009 at 07:55:01 UTCLocation: 7.8° S, 107.3° EDepth: 46kmEvent Id: US2009LBATCreated: 3 weeks, 1 day after earthquake.

Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. A magnitude 7.7 earthquake 165 km South of this one struck Indonesia on July 17, 2006 (UTC), with estimated population exposures of 10,338,000 at intensity V and 48,867,000 at intensity IV, resulting in an estimated 665 fatalities. On May 26, 2006 (UTC), a magnitude 6.4 earthquake 344 km East of this one struck Yogyakarta, Indonesia, with estimated population exposures of 964,000 at intensity IX or greater and 2,305,000 at intensity VIII, resulting in an estimated 5,749 fatalities. Recent earthquakes in this area have caused tsunamis 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.
