Odd Earthquakes Not Letting Up In Central Arkansas

Map of the New Madrid Seismic Zone.
Central Arkansas has been hit with a series of earthquakes recently, more than 500 since September 20.

According to the U.S. Geological Survey (USGS), most were hardly noticeable but one stood out prominently when it hit the Richter scale at a 4.0 on October 11.

Geologists can't say whether the quakes will end anytime soon.

Dr. Horton of the University of Memphis feels that the ample amount of earthquakes in this state is quite unusual.

"In the New Madrid Seismic Zone there's approximately 200 per year, so if we had that many in Central Arkansas in less than a month, something is going on," Dr. Horton told CNN's Sarah Hoye.

The problem is that part of central Arkansas isn't even part of the New Madrid Fault Zone, so researchers are trying to figure out what's causing all those earthquakes.

5.4-Magnitude Quake Shakes Puerto Rico

San Juan - A 5.4-magnitude earthquake struck the U.S. Caribbean territory on Christmas Eve, rattling windows and doors across the island but causing no major damage, officials said.

The quake occurred at a depth of 63 miles south-southwest of the capital of San Juan, according to the U.S. Geological Survey.

Blanca Saez, Ports Authority spokeswoman, told the Associated Press that the international airport is operating as usual. She said six ceiling panels fell at the American Airlines terminal, but that no one was injured.

The earthquake was centered just a couple of miles from the central mountain town of Aguas Buenas.

Emergency officials and police told local media that no damage or injuries have been reported.

Heriberto Sauri, emergency management director, told El Nuevo Dia newspaper that crews would inspect buildings at daylight if necessary.

Rhine-Main region shaken by earthquake

rhine city
Residents of the Rhine-Main region west of Frankfurt were shaken by an earthquake early Thursday morning that scientists say registered 3.5 on the Richter scale.

While such a magnitude is rated as "minor" on the Richter scale, the quake seized the attention of experts because it reached a strength that is very rare for the area.

Residents of the Wiesbaden and Mainz were startled by the deep rumbling that one observer likened to "a train or a truck were driving past the house."

Another observer compared the noise of the quake to "a railway train ... approaching," followed by a dull boom.

The quake occurred at 2:36 am and lasted a few seconds.

Iran: Earthquake Magnitude 6.5 Kills 7, Buries Many

The quake struck late Monday and was felt hardest in mostly rural, relatively sparsely populated areas of Kerman province.
The death toll from a magnitude-6.5 earthquake in southeastern Iran rose to 7, with officials fearing that it will continue to climb, state-run Press TV said Tuesday.

Felt as far away as the Pakistan-Afghanistan border, the quake was particularly strong between the cities of Zahedan and Bam. It struck late at night and hardest in mostly rural, relatively sparsely populated areas of Kerman province, officials said. "Considering the dimensions of the damage, the death toll is expected to rise," the governor general of Kerman was quoted as saying by the IRNA news agency.

Citing eyewitnesses, another state-run news agency IRNA reported that scores of people are trapped in debris of buildings that have been destroyed. Many such sites are in hard-to-reach locations, making any rescue operations even more difficult. Additionally, at least seven aftershocks struck in the four hours since the 6.5-magnitude quake hit at 10:12 p.m. Monday night, according to the Iranian Seismological Center, based at the University of Tehran, and the U.S. Geological Survey.

Javad Kamali, a deputy governor for Kerman province, told the IRNA that the tremor knocked down phone lines throughout the region. Military and law enforcement workers could communicate only using wireless technology, he added. Relief and recovery teams, some from outside the area, have converged around the village of Hosseinabad, between the towns of Fahraj and Rigan, Kamali said.

Some houses destroyed but no casualties reported after yesterday's Ethiopian Magnitude 5.3 earthquake

Image
With thanks to a number Ethiopian readers of Earthquake-Report.com we are able to develop a view on what happened exactly during yesterdays earthquake in Ethiopia. We truly thank our readers for their involvement.

The Ethiopian Addis Abeba university published a report that the earthquake occurred in and around Hossana and had a Magnitude of 5.3. It happened at 3:15 local time.

Following ENA (Ethiopian News Agency) the earthquake lasted 19 seconds and was felt very well in the greater Hossana area.

Some traditional old earthen houses were demolished as a result of the earthquake
Some houses erected with modern materials were left with cracks in the walls.
No people were killed and it is uncertain if people have been injured.

Here are a few of the reports from our readers (they can also be read below our main article published shortly after the earthquake)

Very heavy earthquake in Southern Iran

A very heavy earthquake just happened in Southern Iran.

At 22:11 (10:11 PM) a very powerful and shallow earthquake occurred in the Iranian desert close to Road 93. Some smaller villages are located at a distance of 10 to 20 km from the epicenter.

These villages are: Kaskuh, Darundeh, Dulab, Nemetabad, Sangabad and Bagerabad.

Due to the kind of fault lines Iran earthquakes and the building methods exceeding M 6 are extremely dangerous. It will take a little before the Iranian press will publish more details on this earthquake (our experience based on many prior earthquakes).

The epicenter location has an error margin of 14.6 km.

USGS has calculated that about 735 people will endure a MMI VIII (Severe shaking). 19,000 people a VII, very strong shaking.

The city of Bam, destructed almost completely in another earthquake in a recent history, will get a V MMI shaking today.
