Russian Far East holds seismic hazards threatening Pacific Rim

For decades, a source of powerful earthquakes and volcanic activity on the Pacific Rim was shrouded in secrecy, as the Soviet government kept outsiders away from what is now referred to as the Russian Far East. But research in the last 20 years has shown that the Kamchatka Peninsula and Kuril Islands are a seismic and volcanic hotbed, with a potential to trigger tsunamis that pose a risk to the rest of the Pacific Basin.

The 2009 eruption of Sarychev Peak volcano in the Kuril Islands was captured in this photograph from the International Space Station.

A magnitude 9 earthquake in that region in 1952 caused significant damage elsewhere on the Pacific Rim, and even less-powerful quakes have had effects throughout the Pacific Basin.

"There's not a large population in the Russian Far East, but it's obviously important to the people who live there. Thousands of people were killed in tsunamis because of the earthquake in 1952. And tsunamis don't stay home," said Jody Bourgeois, a University of Washington professor of Earth and space sciences.

Magnitude 5.5 earthquake shakes eastern Indonesia

A strong earthquake struck the eastern part of Indonesia on Wednesday, according to the U.S. Geological Survey. There were no immediate reports of damage.

The magnitude-5.5 quake was centered 56 kilometers (35 miles) under the sea, the U.S. agency reported.

Indonesian seismologist Fauzi, who uses one name, said there was no risk of a tsunami.

Amelia Tagor, a resident of Tual, the town closest to the epicenter, said a brief tremor was felt, but no one panicked.

"We felt it for a few seconds ... but it did not disturb our activities," she said.

Magnitude 2.1 earthquake shakes Camden County, New Jersey

No reports of injuries from 2.1 magnitude quake centered in Clementon.

New Jersey - A loud boom that shock homes in Camden County very early Friday was actually an earthquake.

The U.S. Geological Survey reports that the 2.1 magnitude quake hit near Clementon, N.J. at 12:13 a.m.

The epicenter was near W. Atlantic Avenue and Oak Lane -- a short distance from Clementon Park, according to the USGS.

The whole floor just started shaking really hard, said MaryLou Gicker of nearby Sicklerville.

Residents reported to NBC10 feeling the quake in nearby Pine Hill, Erial and Lindenwold -- some calling and e-mailing the station to say they believe something may have exploded.

"We went outside in the backyard we were looking in the sky to see if there were any fires," said Sicklerville's Bill Chalef. "We were listening for sirens going off to see if there was an accident or explosion."

There was no explosion though, just the movement of the earth.

There were no reports of injuries or damage from the 3.2-mile deep quake.

Magnitude 6.0 quake hits Mexico

An earthquake with a magnitude of 6.0 has hit southwest Mexico at a depth of 60.9 km, according to the United States Geological Survey.

The quake happened near the cities of Tlalchapa and Arcelia.

Reportedly it could be felt as far as the capital, Mexico City, which is 173 km away from the epicenter of the quake.

So far there have been no reports of injuries or damage.

Mexico is one of the world's most seismically active regions.

Beneath it are three large tectonic plates, which are in motion, and cause frequent earthquakes and even occasionally volcanic eruptions.

In 1985, an earthquake of 8.1 in magnitude, one of the largest in the country, killed more than 9,500 people in Mexico City.

No tsunami threat from strong quake in Gulf of Alaska

A strong earthquake in the Gulf of Alaska this morning did not generate a tsunami, officials said.

The quake, which struck at 10:42 a.m., had a magnitude of 6.4 and was centered 349 miles southeast of Anchorage at a depth of 34 miles, according to the U.S. Geological Survey.

The Pacific Tsunami Warning Center in Ewa Beach said there was no tsunami threat. The West Coast and Alaska Tsunami Warning Center also said there was no threat to that region.

There were no reports of damage despite tremors being felt across a large part of southern Alaska. A series of aftershocks also were recorded.

Natasha Ruppert, a seismologist with the Alaska Earthquake Information Center, said this was the largest earthquake in the region since 1987 and 1988, when quakes of magnitude 7.8 and 7.7, respectively, struck.
