This is an automated web page produced after a significant earthquake to give essential information about the earthquake, its aftershocks, and previous earthquake activity in the region. Some of the information here will be updated as aftershocks occur.

Shake Map - For certain earthquakes a map of shaking intensity based on measurements from strong-motion seismographs will be available.

Did You Feel It? - You can report shaking and damage at your location. You can also view a map displaying a summary of data received from all reports.

View Seismograms - View web-based seismograms by station and date.

Maps and History of Earthquakes in this Region

Focal Mechanism - A diagram and table of the P-wave fault plane solution. If sufficient P-wave first motion data are available, a fault plane determination for the earthquake will be available.

Strong-Motion Information - Data from digital accelerographs.
