A moderate earthquake rattled the Los Angeles area early Thursday, waking residents and knocking some items off shelves and walls.
The magnitude 4.5 temblor struck just before 1 a.m. about 4 miles northwest of Chatsworth, according to a preliminary report from the U.S. Geological Survey.
The quick jolt was felt by residents across Los Angeles County, and many reported that their houses vibrated, windows rattled and books, pictures and other items fell.
Hundreds of alarms went off in the Chatsworth area, police said.
"It was a real jerk, then a second jerk and then it just stopped," said Chris Harris, 57, of Canoga Park.
Harris, who was working at his computer when the shaking started, said a large picture fell off a wall in his home.
Chatsworth is about 30 miles northwest of downtown Los Angeles.
CHILE - A moderate earthquake shook the Chilean capital Santiago in the midmorning on Wednesday, causing tall buildings in the city centre to sway. The magnitude 5.0 quake occurred at 10.14am (14H14 GMT) just off the Pacific coast of Chile, 75 kilometres from the port city of Valparaiso. There were no immediate reports of damages.
UTAH - Mine officials insisted Monday‘s accident was caused by a natural disaster. The company released a statement saying the depth of the earthquake occurred in a region that was 3,500 feet deeper than where the miners were. Scientists believe the seismic waves in the area of the Crandall Canyon mine were "the signature of the collapse and that the collapse was not caused by an earthquake." Although mining activities have been shown to produce quakes, the opposite is rare. Scientists say it‘s unusual for a temblor to damage a mine unless it is a big one. In 1976, a 7.8 magnitude quake in China wreaked havoc on coal mines beneath the city of Tangshan. The Crandall Canyon mine is built into a mountain in the rugged Manti-La Sal National Forest, 140 miles south of Salt Lake City, in a sparsely populated area. The region is crisscrossed with geologic faults, and in 1988, a 5.2 magnitude temblor struck 25 miles southeast of the mine.
