October 4, 1987

EUREKA, Calif. (AP) _ A mild earthquake rumbled through extreme Northern California on Saturday but caused no damage or injuries, state officials said.

The quake struck near Eureka at 12:28 p.m. and had a preliminary measurement of 3.9 on the Richter scale, said Lloyd Darrington, a warning controller with the Office of Emergency Services. He said the quake’s magnitude was provided by the Department of Water Resources.

The epicenter of the temblor was placed at 30 miles northeast of Eureka, or about 300 miles north of San Francisco.

Eureka Police Department dispatcher Jan Sylvia said her office received two phone calls, both from residents who wanted to know whether the shaking really was a quake. No damage or injuries were reported in Eureka, however.

No calls or damage reports were received by police in Arcata, a small town about 10 miles north of Eureka that is the home of Humboldt State University. Police at the university received no reports of damage or injury.

Arcata Police Department dispatcher Tamira Spencer was standing in a pharmacy when the quake hit.

″I felt the glass shake,″ said Spencer. ″It was a feeling like the ground was quivering. It was like a flowing motion. Everyone was nervous because of the Los Angeles quake. We all said, ’Oh my God.‴

The Richter scale is a measure of ground motion as recorded on seismographs. An earthquake of 3.5 on the Richter scale can cause slight damage in the local area.

The quake that hit Southern California on Thursday measured 6.1 on the Richter scale.
