PAGER - M 4.5 - 151.9 miles WSW of Dutch Harbor
Alert Version: 4Monday, July 19th, 2010 at 19:09:06 UTCLocation: 52.8° N, 169.7° WDepth: 5kmEvent Id: AK10061461Created: 4 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 6.9 earthquake 130 km East of this one struck the United States Minor Outlying Islands on March 24, 1980 (UTC), with no reported fatalities. On February 27, 1987 (UTC), a magnitude 6.9 earthquake 171 km Northeast of this one struck the United States Minor Outlying Islands, with estimated population exposures of 3,000 at intensity VI and 2,000 at intensity V, with no reported 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.
