Chile is beginning to dig out from a massive 8.2 magnitude earthquake that struck the region at 8:46 p.m. local time Tuesday evening about 52 miles northwest of the mining town of Iquique, according to the USGS. At least five people are confirmed dead and tens of thousands have been evacuated from their homes.

The earthquake touched off tsunami warnings and, according to the BBC, waves up to six feet battered the shoreline in some areas. Widespread power outages, fires and landslides were also complicating rescue efforts. As well, numerous aftershocks were felt throughout the night, including a 6.2 tremor.

Several regions have been declared disaster areas by the government in hopes of "avoiding instances of looting and disorder."

Shortly after the quake, President Michelle Bachelet promised troops and police reinforcement would be sent to maintain public order during rebuilding and repair.

"We're leaving with the children and what we can, but everything is clogged up by people fleeing buildings by the beach," said 32-year old Liliana Arriaza, who was driving away with her three children, according to a Reuters report.

Bachelet said the country had "faced the emergency well" and called on those in the affected regions "to keep calm and follow instructions from the authorities."

An earthquake of magnitude 8.2 has jolted northern Chile, triggering a tsunami alert and the evacuation of thousands of people from coastal areas. At least five people were killed and more than 300 women escaped from a coastal prison.

The quake was centred under the Pacific Ocean 61 miles north-west of the city of Iquique and struck at 8.46pm as thousands of residents were arriving home from work.

As sirens blared and emergency warnings urged residents to evacuate by foot to higher ground, in coastal cities traffic jams ensued as panicked residents sought to escape the coast. The first tsunami surge measured 2.5 metres (8.2ft) and flooded low-lying areas of Iquique including a medical clinic and bus terminal.

A tsunami warning has been issued after a magnitude-8 earthquake struck off the coast of Chile.

The huge tremor has put all of Latin America's Pacific Coast on tsunami alert, the US Geological Survey confirmed.

The quake hit 53 miles (86km) northwest of the mining town of Iquique on Tuesday night.

It occurred just 6.2 miles (10 km) below the seabed - making it feel even more powerful.

It is unknown whether a tsunami has been sparked, but officials believe it is likely.

Friday's 5.1 quake in Los Angeles renews seismologists' fears of catastrophic quake on dangerous Puente Hills fault

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.

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.

Earthquake: 4.1 strikes near Rowland Heights CA; felt over wide area

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.
