Alert Version: 2Thursday, October 15th, 2009 at 18:33:35 UTCLocation: 3.7° S, 123.2° EDepth: 10kmEvent Id: US2009MUCUCreated: 20 hours, 10 minutes after earthquake.
Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. A magnitude 6.2 earthquake 343 km Northwest of this one struck Indonesia on August 15, 2002 (UTC), with estimated population exposures of 3,000 at intensity VIII and 6,000 at intensity VII, with no reported fatalities. On November 29, 1998 (UTC), a magnitude 7.7 earthquake 259 km Northeast of this one struck Indonesia, with estimated population exposures of 5,000 at intensity VIII and 6,000 at intensity VII, resulting in an estimated 41 fatalities.

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.
