Introduction
A magnitude 6.8 (ML BRK; moment magnitude 7.2 NEIC)
earthquake occurred on September 1, 1994 at 8:15 am (PDT).
According to the Seismographic Stations at Berkeley and the USGS
the epicenter is located approximately 145 km west of Petrolia
beneath the Pacific Ocean. The strike-slip earthquake probably
occurred along the Mendocino Fracture Zone.
Strong-motion records are available from 3 CSMIP stations.
Processed data from 2 ground-response and one instrumented
structure are included in this early release. The ground
response stations are located at Cape Mendocino and Shelter Cove.
(Cape Mendocino had the very high acceleration during the April
1992 earthquake.) The structure is a Caltrans bridge near
Eureka. Processed acceleration, velocity and displacement
(preliminary) and spectra from these 3 stations are included in
this report.
The early processing and release of these data take
advantage of new developments in instrumentation and
communications. Files of the processed data are on the
Internet.
