Moderate earthquake rocks northern California

CNN) -- A magnitude 5.2 earthquake shook a rural part of northern California on Tuesday evening, according to the U.S. Geological Survey.

The moderate quake hit shortly after 8 p.m. (11 p.m. ET) about 11 miles east-southeast of Willow Creek, which is about 190 miles northwest of Sacramento.

Nita Rowley with the Williow Creek Chamber of Commerce said she felt the earthquake as a rolling jolt, but had not received any reports of damage.

At the Humboldt County Sheriff's Office in Eureka, Sgt. Diana Freese said several people had called to ask whether a quake had struck. She said the office had received no reports of injuries or damage.

"It was a roll and a shake," she said.

Willow Creek, California - 4-29-08

(AP) A moderate earthquake hit a mountainous region of Northern California on Tuesday night. There are no immediate reports or injury or damage.

The magnitude-5.2 temblor struck at 8:03 p.m., centered about 11 miles southeast of the town of Willow Creek in the Shasta-Trinity National Forest, according to the U.S. Geological Survey. Willow Creek is about 320 miles north of San Francisco.

The quake originated about 11 miles below the surface on an unmapped fault, said David Oppenheimer, a USGS seismologist based in Menlo Park.

Because of its depth, few aftershocks were felt, scientists said. About three were recorded, with the largest measuring a magnitude 2.4, the USGS reported.

The quake was widely felt within about an 80-mile radius, as far north as the Oregon state line and as far south as Mendocino County, according to citizen reports posted on the USGS Web site.

Mary Daher, owner of the Bigfoot Motel in Willow Creek, said the quake lasted 10 seconds or less.

"It was pretty quick and it was pretty strong," Daher said. "It wasn't like one of those rolling earthquakes. It was just a jolt."

She said she and her guests headed outside quickly but she was not aware of any damage. One guest said the quake sent his soda sliding across a table.

The town of 1,800 sits on Highway 299, the main conduit between Redding and Arcata, home of Humboldt State University. It has long been a draw for college students escaping the coastal fog to sunbathe along the nearby Trinity River.

The quirky hamlet, surrounded by thick forests, also markets itself as California's "Bigfoot capital" and displays numerous wood carvings of the mythical creature.

The last significant earthquake in the region was on April 25, 1992, when a magnitude 7.2 temblor struck on the Humboldt County coast near Petrolia, triggering a minor tsunami, according to the USGS.

No tsunami warning was issued for the quake Tuesday night.

Earthquake Rocks Baja California, Leaving 400000 Without Power

February 10, 2008
AP

MEXICO CITY - A moderate earthquake rocked Baja California, shutting down factories near the U.S. border and leaving 400,000 people without power into early Saturday, authorities said.

However, no major damage or injuries were reported.

The quake that struck at 11:12 p.m. Friday had a magnitude of 5.1, according to the U.S. Geological Survey in Golden, Colo. It had initially calculated the magnitude at 5.4.

The quake was centred 25 kilometres southeast of the border city of Mexicali and 160 kilometres east of Tijuana.

"It has been felt pretty widely in Southern California, southwestern Arizona and probably northern Mexico," said USGS geophysicist Jessica Sigala.

It was followed by at least 25 smaller aftershocks.

The quake left about 400,000 people without electricity and 1.2 million without cellular telephone service, but service was restored at around 4 a.m. local time, said Fire Capt. Rene Rosado, director of civil defence in Mexicali.

About 80,000 workers were evacuated from or were unable to enter local factories for Sony, Honeywell and other major corporations, he said, but the factories had all reopened by Saturday afternoon.

Two bridges showed five-to seven-centimetre cracks and were closed until engineers could determine they were safe, he said.

R
escue workers were examining Mexicali schools, many of which are made of adobe, for cracks and other damage, said Alfredo Escobedo, director of Baja California civil protection.

Oscar Vega, the state's education secretary, said classes were expected to resume Monday, but his department would make an announcement when it knows if the buildings are safe.

This quake is farther north than the red warning zone below, but its size is phenomenal.  6.4 and that fits the warning too.

Coastal damage from high waves, but probably not connected to quake.

Manzanita, Oregon) - A magnitude 6.4 earthquake occurred off the Oregon coast Wednesday night, as high winds and rain began pummeling the region - both of which have turned out to be uneventful.

At 5:37 p.m., the U.S. Geological Survey reported the quake about 151 miles off the Oregon coast. It happened at a depth of 6.2 miles, and did not warrant a tsunami warning.

Police dispatchers in numerous coastal communities said they had not received any calls from people who felt the quake. The U.S. Coast Guard also reported no quake-related problems.

Breakers in Manzanita on Wednesday have been enormous, thanks to high winds offshore which tend to make bigger waves well ahead of the actual storm. Seas are reaching 17 foot swells, making the frothy waves come almost up to the dunes of this normally broad, sandy beach.

At around midnight on Wednesday, it is 50 degrees with medium rain, and winds up and down the coast mostly around 25 – 40 mph. Occasional wind gusts as high as 70 mph have been recorded in some spots.
