The PAGER system provides fatality and economic loss impact estimates following significant earthquakes worldwide.

Links to PAGER results for earthquakes occurring within the last 7 days are contained below. The earthquakes are color-coded by the higher of two impact scales - fatalities and economic losses. These impact scales are broken up into four categories. Green alerts are issued when our models estimate zero or very minimal human or economic losses. Yellow alerts are issued when our models estimate up to 100 fatalities, or up to 100 million dollars in losses. Orange alerts are issued for estimates of up to one thousand fatalities, or one billion dollars in losses. Red alerts are issued when either fatalities or losses are predicted to exceed one thousand fatalities or one billion dollars in losses.

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 should always seek the most current PAGER version for any earthquake. PAGER does not directly consider secondary effects such as landslides and tsunami. For tsunami warnings, see the National Weather Service Tsunami Centers.
