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.
Detailed Information and Graphics about the Earthquake
Our data base of earthquake hypocenters contains information
from the 19th century to the present.
Foreshocks and Aftershocks
The following information will be updated as new aftershocks occur.
- An Earthquake Catalog listing the location and magnitude of all earthquakes we have located in the epicentral region (including the mainshock and any aftershocks) for the current year.
- Detailed Map of the earthquakes in this catalog for the epicentral region.
- Seismic Activity as a function of time in the epicentral region since the time of the mainshock.
If sufficient P-wave first motion data are available,
a fault plane determination for the earthquake
will be available in the form of
Preliminary Strong Motion Information

Preliminary Summary of the Public's Web Responses
As of June 26 we have received over 400 responses to a WEB based
A preliminary summary of these responses
will be updated as we receive more reports.
Such information helps us to understand more about this
earthquake as well as older, pre-instrumental events.
