Historical Earthquakes (with MMI)
|Date (UTC)||Dist (km)||Mag||Max MMI (#)||Shaking Deaths|
Recent earthquakes in this area have caused secondary hazards such as landslides and liquefaction that might have contributed to losses.

PAGER content is automatically generated, and only considers losses due to structural damage. Limitations of input data, shaking estimates, and loss models may add uncertainty. PAGER results are generally available within 30 minutes of the earthquake’s occurrence. However, information on the extent of shaking will be uncertain in the minutes and hours following an 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.
