Detailed Information and Graphics about the Earthquake

Our data base of earthquake hypocenters contains information from the 19th century to the present. Included are:

A map of the Pacific Northwest showing the location of the earthquake (in red) plus prior earthquakes M > 3.5. 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 3.5 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 3.5. These are the most significant historical earthquakes in the vicinity of the mainshock (see the closer view map above).
A map showing the location of the earthquake relative to cities.
A map showing the location of the earthquake relative to the nearest seismograph stations that recorded it.
A detailed list of all earthquakes (M > 1.0) that occurred in the vicinity of the special earthquake in the previous two years. For the locations of these events see the next map.
A map of all earthquakes (M > 1.0) that occurred in the two years prior to the special earthquake. Detailed area shown is just few kilometers around the mainshock.
A List of the nearest 20 strong motion sites

Earthquake Mechanism

If sufficient P-wave first motion data are available, a fault plane determination for the earthquake will be available in the form of

A diagram of the fault plane solution(s). In some cases more than one solution may fit the data.
A table describing the fault plane solution(s) summarizing the characteristics of possible fault planes ("A" and "B") that are consistent with the recorded first-motion data.

Moment Tensor Estimates of the Earthquake size may also be available. To see, check at Oregon State U.

Preliminary Strong Motion Information

Strong-motion information from digital accelerographs.
