Middle East: Earthquakes hit Northern Emirates

Measured 3.0 and 2.0 on Richter scale; no damage reported

Tremors from earthquake were felt twice in the Northern Emirates on Sunday evening but there was no news of damage, according to the UAE's national network stations for monitoring earthquakes.

For the first time, the quake was felt in Fujairah and Hatta areas at 5.10 pm UAE time measuring 3.0 on the Richter scale. While the second quake was felt only in Fujairah at 7.10 pm measuring 2.0.

National Center of Meteorology & Seismology (NCMS) said the epicentre of the earthquakes was 24 kilometres southwest of Fujairah and 10 kilometres east of Hatta.

The residents living in the vicinity of epicentre said they felt mild tremors but there was no news of loss or damage.

On January 19, tremors from a magnitude 7.1 earthquake in Pakistan were felt across the UAE.

The UAE, which is located close to one of the world major earthquake zone in Iran, has some fault zones in the northern emirates.

US: Nearly 60 Small to Moderate Earthquakes Strike Arkansas and Are Widely Felt

Nearly 60 small and moderate earthquakes struck Arkansas since Feb. 15, 2011, the most recent a magnitude 4.3 earthquake this morning 37 miles away from Little Rock. Many of the earthquakes are large enough to be felt.

"These earthquake swarms are not that unusual for the region," said Harley Benz, scientist in charge at the U.S. Geological Survey National Earthquake Information Center. "Central Arkansas has a history of earthquake activity with a swarm of thousands of earthquakes smaller than magnitude 4.5 in the early 1980s and another swarm in 2001, known as the Enola earthquake swarms."

Citizens are encouraged to report any experience feeling the earthquake(s) at the USGS Did You Feel It? website. The earthquake swarm that began Tuesday may continue. This area is slightly south of and most likely related to similar ongoing activity involving hundreds of small earthquakes near Guy, Ark., from August 2010 to present.

Scientists do not know why swarms start, why they stop, or how long to expect them to last. The possibility of a larger earthquake cannot be discounted, but none of the other swarms have caused any reason to expect a future earthquake large enough to cause significant damage in central Arkansas.

USGS scientists have been working with their partners at the Center for Earthquake Research and Information (CERI) at the University of Memphis and the Arkansas Geological Survey (AGS) to carefully monitor this situation. They have deployed a local network of stations - an array - that measure seismicity in the Greenbrier-Enola area to augment regional seismic stations. The CERI and AGS array and personnel are the best source of the most current information about the new earthquake swarm. The AGS and CERI are investigating whether the earthquakes occur naturally or are related to human activities.

US: Earthquake Magnitude 3.5 Strikes Southern Alabama Coast


Authorities say a 3.5-magnitude earthquake has shaken southern Alabama, and people have reported feeling the quake as far away as Birmingham, Ala.

Residents in the Pensacola area of the Florida panhandle also say they felt the quake, according to reports from the U.S. Geological Survey.

Information from the Geological Survey indicates the quake happened at 5:15 p.m. Friday.

Officials say the epicenter was near the tip of the Fort Morgan Peninsula at the mouth of Mobile Bay in Baldwin County.

US: Earthquake activity near Mount St. Helens volcano quietly continues

Aftershocks from Monday's 4.3 magnitude earthquake northwest of Mount St. Helens have continued all week, but most of them have been too small to be felt any distance away.

The most recently recorded shock occurred at 8:07 a.m. Friday about six miles from the volcano, the same vicinity as the temblor that jolted a broad area of Southwest Washington and Northwest Oregon at 10:35 a.m. Monday, according to the University of Washington geophysics lab in Seattle. Two quakes measuring 2.4 and another hitting 2.3 occurred late in the week.

None of the earthquakes is known to have caused any damage or injuries.

Ghana: Parts of Accra Metropolis experience tremor

Residents of some communities in Accra at dawn on Wednesday experienced what eyewitnesses described as an earth tremor.

The incident, which occurred around 0400 hours affected communities like Taifa, Dome, Tantra Hills, Achimota, Kwabenya, Ashongman and East Legon, from where residents called a local radio station for confirmation.

Official sources, however, could not confirm the incident to the Ghana News Agency (GNA) as the nation did not have the equipment to measure incidence of earthquakes or tremors.

Update: Seventeen Earthquakes Shake Greenbrier, Arkansas Wednesday

Click here to watch the video.

People who live in northern Faulkner County are feeling the ground shake again.

Seventeen earthquakes happened in the Greenbrier area Wednesday between 3:30 in the morning and 11:05 in the evening. The strongest of those registered 3.5 on the Richter Scale. The second strongest was a 2.9 tremor.

There have been dozens of quakes since Monday around Greenbrier according to the United States Geological Survey (USGS). Click here for more information.

According to Wikipedia, earthquakes that register 2.0 to 2.9 in magnitude are classified as minor and are generally not felt. There are about 1,000 of these everyday around the world.

Those that measure 3.0 to 3.9 are also classified as minor. They are often felt, but rarely cause damage and there are 49,000 of them around the world daily.

US: Swarm of Unexplained Earthquakes Strikes Arkansas

Jim Sutterfield was briefly puzzled by a thumping sound that seemed to slam the back of his office chair. But when the small-town Arkansas fire chief turned and saw no one was around, he quickly realized it was just an earthquake - again.

"That was only my second time to feel one, but others here have felt them for three or four months now," Greenbrier chief Jim Sutterfield said after feeling the latest tremor on Wednesday. "Now when it happens, people say, 'Well, there's another one.'"

Several small earthquakes ranging in magnitude from 1.8 to 3.8 have rattled the north-central Arkansas cities of Greenbrier and Guy this week, and the cause is unknown.

The U.S. Geological Survey has reported more than 30 earthquakes in the area since Sunday, including a magnitude 3.8 quake Thursday morning and at least 16 others occurring Wednesday, two of which were magnitude 3.2 and 3.5. More than 700 quakes have occurred in the region over the past six months.

Scott Ausbrooks, geohazards supervisor for the Arkansas Geological Survey, said the quakes are part of what is now called the Guy earthquake swarm - a series of mild earthquakes that have been occurring periodically since 2009. A similar swarm occurred in the early 1980s when a series of quakes hit Enola, Ark.

Philippines: 7 volcanic quakes recorded at Taal

Taal Volcano in Batangas province showed renewed activity on Wednesday, with state volcanologists recording at least seven quakes in the last 24 hours.

In its Thursday report, the Philippine Institute of Volcanology and Seismology reiterated Taal's main crater remains off limits to the public.

"Alert Level 1 is still enforced over Taal Volcano. This means that a hazardous eruption is not imminent. However, the public is reminded that the main crater should be strictly off-limits due to sudden occurrence of steam explosions and accumulation of toxic gases," Phivolcs said on its website.

It added that the northern portion of the main crater rim, in the vicinity of Daang Kastila trail, may also be dangerous when increased steam emission is reactivated along existing fissures.

Phivolcs also reminded the public that the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended.
