The magnitude 5.1 earthquake that rattled Southern California on Friday was a 10-second reminder of a fault that seismologists believe can produce a catastrophic disaster. The Puente Hills thrust fault is so dangerous because of its location, running from the suburbs of northern Orange County, through the San Gabriel Valley and under the skyscrapers of downtown Los Angeles before ending in Hollywood. Experts say a major, magnitude 7.5 earthquake on the fault could do more damage to the heart of Los Angeles than the dreaded Big One on the San Andreas fault, which is on the outskirts of metropolitan Southern California.

This week's predawn earthquake in Pico Rivera woke up people around Southern California, but the magnitude 4.4 temblor didn't cause major damage. But scientists said the quake should serve as a warning about a fault that runs through a large swath of densely populated Los Angeles County and is capable of producing a devastating, magnitude 7.5 quake. The Puente Hills thrust fault is less well-known than other faults such as the San Andreas and Newport-Inglewood. But there is growing scientific evidence that it is particularly dangerous.

Previously secret oil company data reveal a major active fault system under metropolitan Los Angeles that most likely caused the magnitude 5.9 Whittier Narrows earthquake in 1987, researchers said Thursday. This buried fracture may be capable of larger and even more damaging earthquakes than the 1994 Northridge quake, according to the research, published today in Science.

Newly developed computer models applied for the first time to the Puente Hills fault beneath downtown Los Angeles suggest a 7.5 magnitude quake could cause as much as a quarter of a trillion dollars in damage and kill as many as 18,000 people. Scientists have known for the last two years that the fault is the major quake threat to urban Los Angeles, but the new projections released Wednesday provide the first rough picture of the potential loss of life and property.

The cluster of earthquakes that began Friday night in La Habra appear to have struck on a fault underneath the Puente Hills thrust fault, scientists said Wednesday. Friday's earthquake has not provoked earthquakes on either the main Puente Hills fault or the nearby Whittier fault. Friday's magnitude-5.1 quake “was relatively shallow and thus did not significantly perturb the parts of the Puente Hills thrust or the Whittier fault, where we expect a major earthquake to start,” said Caltech seismologist Egill Hauksson.

The Puente Hills fault, which scientists believe could be responsible for Friday's 5.1 earthquake in La Habra, is considered very dangerous. Here are some basic questions about the fault. Q: What would be the difference in shaking between a 5.1 quake and a truly huge quake? Friday night's earthquake was caused by the underground fault slipping for half a second, said U.S. Geological Survey seismologist Lucy Jones, prompting about 10 seconds of shaking at the surface. But a 7.5 quake on the Puente Hills fault could cause the fault to slip for 20 seconds - and the shaking could last far longer.

A magnitude-5.1 earthquake centered in northern Orange County rippled across the Los Angeles Basin, and preliminary indications suggest the long-feared Puente Hills thrust fault may have caused it. The quake caused pictures to fall of walls, glass items to shatter and furniture to tumble down in some homes near the epicenter. There were also reports of some gas and water line damage as well as scattered power outages. At a home in San Dimas, dozens of pictures flew off walls, a ladder fell and dented a car in garage and medicine cabinets flew open and emptied out. In Orange, a few miles to the east of the epicenter, patrons at a BJ's pub went from boisterous conversation to tense silence.

An extensive fault system discovered four years ago running deep beneath the heart of Los Angeles is capable of generating earthquakes up to magnitude 7.5 -- massive shakers larger than any in the modern history of the Los Angeles Basin. The Puente Hills fault, which winds through the area's fractured underbelly for about 25 miles, from northern Orange County to Beverly Hills, has generated at least four earthquakes ranging from magnitude 7.2 to 7.
