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.

Maps and History of Earthquakes in this Region

• A map of the Pacific Northwest showing the location of the mainshock (in red) plus prior earthquakes M > 3.0. Shallow events are black. Events deeper than 35 km are green.
  
• A map showing a closer view of the earthquake and prior historical earthquakes with magnitude 3.0 or greater. Shallow events are black. Events deeper than 35 km are green.
  
• A list of 10 big earthquakes preceding the mainshock that are closest to it and have a magnitude greater than 3.0. These are the most significant historical earthquakes in the vicinity of the mainshock (see closer view map above).
  
• A map showing the location of the mainshock relative to cities.
  
• A map showing the location of the mainshock relative to the nearest seismograph stations that recorded it.
  
• A general map of significant historical earthquake locations in the Pacific Northwest.
  
• A detailed list of all earthquakes (M > 1.0) that occurred in the two years prior to the mainshock in the area shown on the next map.
  
• A map of all earthquakes (M > 1.0) that occurred in the two years prior to the mainshock. Detailed area shown is just few kilometers around the mainshock.
  
• A list of the nearest 20 strong motion sites
  

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 - for some earthquakes a ShakeMap based on recorded data from digital accelerographs is available.
