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, though the San Gabriel Valley and under the skyscrapers of downtown Los Angeles before ending in Hollywood.

Experts say a major 7.5-magnitude 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 located on the outskirts of metropolitan Southern California.

The size of Friday's quake was considered moderate, but it packed a punch. Residents within 10 miles of the epicenter in La Habra reported toppled furniture, broken glass and fallen picture frames. Several water mains broke, and a rockslide in Carbon Canyon caused a car to overturn, leaving those inside with minor injuries.

Officials said more than a dozen homes were red-tagged because of possible structural damage.

Animals can often sense trouble long before humans. These Bison are coming down the hills in droves and fleeing on the road to get away from Yellowstone. Is the volcano there going to erupt?

The University of Utah, a YVO member agency, sent out the following press release about a magnitude 4.8 earthquake that occurred this morning at 6:34 AM MDT.

PRESS RELEASE
University of Utah Seismograph Stations
Released: March 30, 2014 08:15 AM MDT

The University of Utah Seismograph Stations reports that a light earthquake occurred at 06:34 AM on March 30, 2014 (MDT). The epicenter of the magnitude 4.8 shock was located 4 miles north-northeast of Norris Geyser Basin in Yellowstone National Park, Wyoming. This earthquake is part of a series of earthquakes that began in this area on Thursday, March 27. As of 8:15 am today, this series has included at least 25 earthquakes in addition to the main shock, with the largest of magnitude 3.1. The magnitude 4.8 main shock was reported felt in Yellowstone National Park and in the towns of West
Yellowstone and Gardiner, Montana.

Anyone who felt the earthquake is encouraged to fill out a survey form on either the Seismograph stations web site: www.quake.utah.edu or the U.S. Geological Survey web site: earthquake.usgs.gov.

A shallow magnitude 4.1 earthquake was reported Saturday afternoon one mile from Rowland Heights, according to the U.S. Geological Survey. The temblor occurred at 2:32 p.m. at a depth of 5.6 miles. (It was originally reported as a 4.4 magnitude.)

Updated at 2:40 p.m.

The quake was centered not far from the epicenter of Friday's 5.1 temblor in La Habra. There have been more than a hundred aftershocks since then, but this one was the largest.

Saturday's quake was felt across a large area of Southern California. There were no immediate reports of damage or injuries.

Across Northern Orange County, officials were tallying moderate damage from Friday's quake. Much of the damage was in La Habra, Fullerton and Brea.

Recent earthquake in Los Angeles a warning that California overdue for a big earthquake?

Was the recent earthquake in Los Angeles a warning of more to come? 'Earthquake Storms' author John Dvorak shares his thoughts.

On March 17, a mild earthquake rattled countless Los Angeles-area residents awake shortly before their alarms went off at 6:30 a.m. The Monday morning temblor was the first notable L.A.-area quake in years.

A lengthy vacation from earthquakes certainly sounds nice. But John Dvorak, a geophysicist who now works at a astronomical observatory in Hawaii, warns that a quake break can just be the calm before the earthquake storm.

He makes his case that the Golden State is in for trouble in his readable and aptly named new book "Earthquake Storms: The Fascinating History and Volatile Future of the San Andreas Fault."

But it's not just Californians who should pay attention to his exploration of earthquake science, the unfolding mysteries of geology, and the gaps in our seismic knowledge.

As he notes in an interview, plenty of other parts of the country are vulnerable to earthquakes, including the Northwest, the Midwest, the South and - yes - even the Big Apple.

Comment: Southern California just experienced another earthquake this week and the ring of fire has been quite active recently:

The U.S. Geological Survey has recorded 14 earthquakes in Oklahoma since about 9:30 p.m. Friday, the largest being a magnitude 4.0.

The 4.0 magnitude quake was recorded at 10:05 p.m. Friday about seven miles south of Langston. Three other quakes of magnitude 2.9, 3.0 and 3.3 were recorded Saturday afternoon in the Medford area.

The other quakes ranged from magnitude 2.4 to 2.9. No injuries or damage are reported.

Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest felt by humans.
