This information will be updated as needed. A regional map showing the location of the earthquake. A Intermediate scale map showing the location of the earthquake and prior historical earthquakes with magnitude 3. 5 or greater. A list of 10 big earthquakes preceding the mainshock that are closest to it and have a magnitude greater than 3.5. For the locations of these events see the next map.
Detailed area shown is just few kilometers around the mainshock.
GNW is located on Green Mountain, near Gold Mountain on the Kitsap Peninsula. A sample strong-motion accelerogram from a new experimental system at the U of W shows a maximum peak ground acceleration of 0.0004 g. In some cases more than one solution may fit the data.
