Alert Version: 6Friday, July 23rd, 2010 at 21:29:10 GMTLocation: 37.7° N, 122.5° WDepth: 8kmEvent Id: NC71436076Created: 5 hours, 10 minutes after earthquake.
Population exposure estimates are NOT a direct estimate of earthquake damage; comparable shaking will result in significantly lower losses in regions with well built structures than in regions with vulnerable structures. Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist.

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.
