PAGER - M 6.7 - CELEBES SEA
Alert Version: 1Wednesday, October 7th, 2009 at 21:41:14 UTCLocation: 4° N, 122.6° EDepth: 583kmEvent Id: US2009MLCBCreated: 15 minutes, 50 seconds after earthquake.
Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake resistant construction. A magnitude 6.5 earthquake 375 km Southwest of this one struck Indonesia on October 25, 1983 (UTC), with estimated population exposures of 62,000 at intensity VIII and 97,000 at intensity VII, resulting in an estimated 2 fatalities. On August 16, 1976 (UTC), a magnitude 8.0 earthquake 300 km Northeast of this one struck Moro Gulf, Philippines, with estimated population exposures of 1,484,000 at intensity VII and 2,888,000 at intensity VI, resulting in an estimated 7,079 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.
