Detailed Information and Graphics about the Earthquake

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

Foreshocks and Aftershocks

The following information will be updated as new aftershocks occur. Note that the locations of early epicenters are quite scattered because we had no seismographs near Spokane. Recent epicenters have been located using a new seismograph (SPUD) located in Spokane as well as more distant seismographs.

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

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