A moderate earthquake struck Northern California's coast Monday afternoon, rattling nerves around the Oregon border but yielding no immediate reports of major injuries or damage, officials said.
The magnitude-5.6 quake struck at 1:07 p.m. about 18 miles inland in an unincorporated part of Humboldt County, the U.S. Geological Survey said. The epicenter was a rural area near the small community of Weitchpec on the Hoopa Valley Indian Reservation, about 240 miles north of San Francisco and about 60 miles south of the Oregon border.
The temblor was widely felt within a 100-mile radius, according to the USGS website.
The Humboldt County Sheriff's Department and Eureka Police Department sent deputies and officers to check on residents, but dispatchers said there were no immediate reports of emergencies. Things also seemed fine on the Hoopa reservation, according to Byron Nelson Jr., the tribe's vice chairman.
"It was just a mild shaking. It wasn't a sharp jerk," said Sgt. Gene McManus of the Del Norte County Sheriff's Department, a neighboring agency that also saw no immediate problems.
Children's building blocks tumbled at Weitchpec Elementary School, but the staff and students took the shaking in stride.
Kate Lowry, the school's sole teacher, told The Associated Press in a phone interview that she, her aide and the 19 children followed their earthquake drill procedure and filed out of the building.
"We were still moving as we were walking across," Lowry said. "Once we got down in the field, it had stopped."
At nearby Pearson's Grocery Store, Karen Pearson watched cans fall off the shelves as a man yelled for people to get out.
"It was very scary because you have no control of these things," Pearson said. "Hopefully it's over."
Debbie Bailey, who owns an office supply shop in Hoopa, about five miles from the epicenter, said only a few items fell off shelves there. She described the jolt, which lasted four or five seconds, "like a pick-up-and-move, like a soft wave."
Seismologists say the far-northern coast of California is the most seismically active area in the state, but the potential for damage and injuries there is smaller because it's less populated.
The most damaging earthquake in recent years occurred near Eureka on Jan. 9, 2010, when a magnitude-6.5 temblor caused more than $40 million in damage and one serious injury _ an elderly woman who fell and broke her hip. It was followed a month later with a magnitude-5.9 quake in the same region that caused much less damage.
Lainey McDonald, who was standing in the office of her roofing supply company in Eureka, said Monday's rumblings did not feel as bad as those past events.
"I was asking myself, `Is it really still going or is it my knees?'" McDonald said. "It was still going. It definitely got my attention."
