A magnitude 3.8 earthquake struck central Arkansas on Thursday morning, the U.S. Geological Survey reports.

The agency put the quake's depth at only 2.2 miles and said it was centered about two miles from the town of Greenbrier.

It was the third quake above magnitude 3.2 in the area in the past 24 hours.

Last October, a 4.0 quake stuck near Guy, Arkansas, only six miles from Thursday's temblor.

At that time, officials said they were investigating what could be behind a series of 500 quakes in under a month.

A strong earthquake measuring 5.2 on the Richter scale shook eastern and southern Crete on Monday morning at 9:49 a.m. The quake was felt throughout the region, especially around Ierapetra but also in the city of Iraklio.

According to the Geodynamic Institute of the National Observatory in Athens and the Geophysics Laboratory at the Thessaloniki University, the epicentre of the quake was 368 kilometres south southeast of Athens and 25 kilometres southwest of Lasithi in the Ierapetra region. It follows an earlier earthquake measuring 4.2 on the Richter scale that occurred in roughly the same region on February 23.

There were no reports of damages.

A magnitude 7.3 earthquake triggered a small tsunami along Japan’s northeastern coast Wednesday and shook buildings hundreds of miles away in the capital Tokyo.

A 24-inch (60-centimeter) tsunami reached the coastal town of Ofunato and other towns reported smaller waves reached shore about 30 minutes after the quake, which occurred at 11:45 a.m.

Japan’s meteorological agency said the quake was centered 150 kilometers off the northeastern coast at a depth of about eight kilometers.

There are no reports of significant damage or injuries.

Strong Earthquakes Hit Tonga And Japan

Posted Image

A strong magnitude 6.4 earthquake has struck at sea northwest of Tonga, an archipelago in the South Pacific Ocean.

There are no immediate reports of injuries or damage and no tsunami warning has been issued.

The U.S. Geological Survey says Thursday’s quake was centred 438 kilometres northwest of the Tongan town of Neiafu at a depth of 23 kilometres.

Meanwhile, a 6.1 magnitude earthquake was recorded off the east coast of Honshu in Japan this morning, almost three weeks after a 8.9 magnitude quake and tsunami devastated coastal parts of the northeast of the country.

A fresh tsunami warning has been issued by the Japan Meteorlogical Agency after a magnitude 7.1 earthquake hit the country.

The earthquake struck at 9.16am GMT at a depth of 10km in Iwaki, located in the Fukushima prefecture where authorities have been battling to control the dangerous levels of radiation spewing from a crippled nuclear plant.

Tokyo Electric Power Company issued a temporary evacuation of Fukushima nuclear plant following today's earthquake. Reports suggest that the latest earthquake has caused power outages leading to water not being pumped into reactors 1, 2 and 3.

Two smaller earthquakes, magnitude 4.6 and 5.0, struck the same area earlier today. Today's much larger quake was quickly followed by an aftershock measuring 5.3 on the Richter Scale.

It’s the second tsunami alert to be issued in Japan in less than a week. A 7.2-magnitude earthquake was recorded off Japan’s northeastern coast on Thursday, shaking buildings in the country’s capital Tokyo for over a minute.

Hundreds of aftershocks have shaken the northeast region devastated by the March 11 earthquake, but few have been stronger than 7.0. There were two other earthquakes in the same region earlier today, measuring 4.5 and 4.6 on the Richter Scale.

At least five countries located on the Pacific Ring of Fire have experienced earthquakes greater than a magnitude of 5 over the past 24 hours.

A 5.4 magnitude earthquake hit north-eastern Australia on Saturday afternoon. The United States Geological Survey (USGS) said the quake took place at 3.30pm local time (0530 GMT) about 124 kilometres southeast of Townsville, Queensland. The quake was measured at a depth of 10 kilometres. Queensland was hit by another 5.4 magnitude quake on 16 March last.

Meanwhile, Christchurch in New Zealand has been hit by more aftershocks this afternoon, leaving several parts of the city without power. The strongest of the tremors measured 5.2 on the Richter Scale. The country’s second largest city was hit by a 6.3 magnitude earthquake in February. 181 people were killed.

Elsewhere, Japan was rattled by a 5.9 magnitude aftershock on Saturday afternoon but there were no initial reports of damage and no risk of a tsunami.

Taiwan was hit by a quake measuring 5.8 on the Richter Scale. The quake struck 220km east of Keelung City. Tonga, an archipelago in the South Pacific Ocean, also experienced a 5.7 magnitude earthquake last night.

The “Ring of Fire” is an arc stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America. The Ring of Fire is composed over 75% of the world’s active and dormant volcanoes.

A magnitude 6.8 earthquake has been recorded between New Caledonia and the Loyalty Islands, an archipelago in the south Pacific.

The epicentre was about 149 kilometres off Ile Tadine, and more than 1,600 kilometres from Brisbane, Australia. The U.S. Geological Service and the European-Mediterranean Seismological Centre said the quake hit at 0855 GMT, approximately 26.5 km beneath the ocean.

No injuries or damage were immediately reported.

The Global Disaster Alert and Coordination System has released a green warning on the tsunami. The Pacific Tsunami Warning Center says there was no threat of a widespread tsunami based on historical earthquake and tsunami data.

A 7.0 magnitude earthquake struck in the same region earlier this year. The January 13 quake hit off the New Caledonia islands, a French territory in the Southern Pacific.

The Loyalty Islands archipelago consists of six inhabited islands: Lifou Island, Maré Island, Tiga Island, Ouvéa Island, Mouli Island, and Faiava Island, as well as several smaller uninhabited islands and islets.

The Loyalty Islands were so named toward the end of the 18th century by the British merchant ships that discovered these islands and found these people of dual Melanesian and Polynesian heritage to be 'honest and agreeable'.

BREAKING: A magnitude 7.1 earthquake has struck off Vanuatu
Quake strikes off Vanuatu



A magnitude 7.1 earthquake struck 133 kilometres south-west off the Pacific island of Vanuatu, the US Geological Survey (USGS) says.

The Pacific Tsunami Warning Centre says "no destructive widespread tsunami threat exists based on historical earthquake and tsunami data".

The quake was 26 kilometres deep and struck 135 km from Isangel in Vanuatu and 147 km from the Loyalty islands, part of the French territory of New Caledonia.

"Based on all of the local analytical data, a tsunami is not expected within Vanuatu," an official for the Vanuatu Meteorological Services told Reuters by telephone from the capital, Port Vila.

A receptionist at a hotel in Ouvea in the Loyalty Islands said there was no immediate sign of damage.

"It was not a particularly strong tremor but we definitely felt it. There was no breakage, no damage," the receptionist at the Hotel Paradis d'Ouvea said.

Haiti and the neighboring Dominican Republic could be in for a period of periodic powerful earthquakes, according to a scientific study released Thursday.

The study says Haiti's 7.0-magnitude earthquake two years ago is likely to be the first of several quakes of a similarly powerful magnitude.

The Jan. 12, 2010, earthquake caused widespread damage in the Haitian capital and surrounding cities. Officials say the disaster killed 314,000 people and toppled thousands of crudely built homes.

"The 2010 Haiti earthquake may mark the beginning of a new cycle of large earthquakes on the Enriquillo fault system after 240 years of seismic quiescence," lead author William Bakun of the U.S. Geological Survey wrote. "The entire Enriquillo fault system appears to be seismically active; Haiti and the Dominican Republic should prepare for future devastating earthquakes."

The authors document a series of four major earthquakes of magnitude 6.6 and higher that struck Hispaniola, the Caribbean island shared by Haiti and the Dominican Republic. The phase began in 1701, near the site of the 2010 quake, and ended in 1770.

There was no evidence of significant earthquake activity on the Enriquillo fault system in the 240 years from 1770 until the 2010 disaster, except for an earthquake in 1860 that likely occurred offshore, the study said.

The possibility that a newly active period has begun underscores the need for Haiti and the Dominican Republic to focus on building seismic-proof structures, Bakun said.

"Whatever information people have to guide reconstruction efforts in Haiti ... is certainly useful," Bakun said by telephone from Merlo Park, California.

The study appears in the February edition of the Bulletin of the Seismological Society of America.

Moderate quakes have struck the Dominican Republic in recent weeks but there were no reports of damage.

Past 3,500 years saw seven M9s
Kyodo


OSAKA — At least seven magnitude 9 earthquakes have occurred along the Pacific coast from Hokkaido to Tohoku over the past 3,500 years, generating huge tsunami that inundated the coastline, a new study by a Hokkaido University professor says.

Kazuomi Hirakawa, professor of natural geography at the university, drew the conclusion after analyzing deposits believed linked to tsunami at more than 400 sites from Nemuro in Hokkaido to Kesennuma, Miyagi Prefecture, in Tohoku's Sanriku region.

Deposits of seabed gravel and fossilized marine life washed ashore by each of the seven massive tsunami except the one on March 11 turned out to be identical in age at nearly all of the survey locations, Hirakawa said Wednesday.

The analysis covers a much wider area than any previous surveys.

Some earthquakes expected along Rio Grande Rift in Colorado and New Mexico, new study says.

The Rio Grande Rift, a thinning and stretching of Earth’s surface that extends from Colorado’s central Rocky Mountains to Mexico, is not dead but geologically alive and active, according to a new study involving scientists from the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences.

“We don’t expect to see a lot of earthquakes, or big ones, but we will have some earthquakes,” said CU-Boulder geological sciences Professor Anne Sheehan, also a fellow at CIRES. The study also involved collaborators from the University of New Mexico, New Mexico Tech, Utah State University and the Boulder-headquartered UNAVCO. The Rio Grande Rift follows the path of the Rio Grande River from central Colorado roughly to El Paso before turning southeast toward the Gulf of Mexico.

Sheehan was not too surprised when a 5.3 magnitude earthquake struck about 9 miles west of Trinidad, Colo., in the vicinity of the Rio Grande Rift on Aug. 23, 2011. The quake was the largest in Colorado since 1967 and was felt from Fort Collins to Garden City, Kan.

Along the rift, spreading motion in the crust has led to the rise of magma -- the molten rock material under Earth’s crust -- to the surface, creating long, fault-bounded basins that are susceptible to earthquakes, said Sheehan, a study co-author and also associate director of the CIRES Solid Earth Sciences Division. The team studied the Rio Grande Rift region to assess the potential earthquake hazards.

Using Global Positioning System instruments at 25 sites in Colorado and New Mexico, the team tracked the rift’s miniscule movements from 2006 to 2011. “Questions we wanted to answer are whether the Rio Grande Rift is alive or dead, how is it deforming and whether it is opening or not,” said Sheehan.

The high-precision instrumentation has provided unprecedented data about the volcanic activity in the region. Previously, geologists had estimated the rift had spread apart by up to 0.2 inches or 5 millimeters each year, although the errors introduced by the scientific instruments were known to be significant. “The GPS used in this study has reduced the uncertainty dramatically,” Sheehan said.

Using the latest high-tech instrumentation, the scientists found an average strain rate of 1.2 “nanostrain” each year across the experimental area, the equivalent of about one-twentieth of an inch, or 1.2 millimeters, over a length of about 600 miles. “The rate is lower than we thought but it does exist,” Sheehan said.

The researchers also found the extensional deformation, or stretching, is not concentrated in a narrow zone centered on the Rio Grande Rift but is distributed broadly from the western edge of the Colorado Plateau well into the western Great Plains. “The surprising thing to come out of the study was that the strain was so spread out,” Sheehan said.

Results of the study are published in the January edition of the journal Geology.

The team plans to continue monitoring the Rio Grande Rift, probing whether the activity remains constant over time, said lead study author Henry Berglund of UNAVCO, who was a graduate student at CU-Boulder working at CIRES when he completed this portion of the research. Also, the team may attempt to determine vertical as well as horizontal activity in the region to tell whether the Rocky Mountains are still uplifting or not, Berglund said.

“Present-day measurements of deformation within continental interiors have been difficult to capture due to the typically slow rates of deformation within them,” Berglund said. “Now with the recent advances in space geodesy we are finding some very surprising results in these previously unresolved areas.”

As far as the potential for future earthquakes in the region, the study’s results are unequivocal, however. “The rift is still active,” Sheehan said.

The new study also is co-authored by CU-Boulder Associate Professor and CIRES Fellow Steven Nerem, Frederick Blume of UNAVCO, Anthony Lowry of Utah State University, Mousumi Roy of the University of New Mexico and Mark Murray of New Mexico Tech.

The National Science Foundation provided the funding for this study and the NSF-funded EarthScope program and UNAVCO provided instruments, equipment and engineering services. The Boulder-headquartered UNAVCO is a nonprofit, university-governed consortium that facilitates geosciences research and education.

Scores of people are reported to have been injured after a powerful earthquake struck the coastal region of Peru.

Officials say between 60 and 70 people were admitted to hospitals following the tremor.

Several homes were damaged and there were power outages in central Peru.

There were no immediate reports of fatalities.

Damaging Earthquakes Database 2011

The Year in Review


Posted Image


2011 has played host to the largest two earthquakes, economically speaking, in the history of the countries of Japan and New Zealand. The M9.0 Tohoku earthquake and tsunami of 11th March, 2011 proved to be the most expensive earthquake of all time, causing between $400-700 billion USD in total losses and approximately 19000 deaths, while the Christchurch earthquake (a M6.3 quake close to the city of Christchurch) caused a huge building stock loss and approximately $15-20 billion USD damage with around 80% insured losses. Their respective aftershocks caused further damage. Significant losses were also seen in Turkey from the Van earthquake in October, in the India-Nepal-Tibet region in September, in China from numerous earthquakes in the Yunnan and Xinjiang Provinces and in the USA from the Virginia earthquake.
Author’s Notes

We hope that you enjoy the CATDAT Yearly Review of Damaging Earthquakes in 2011. The CATDAT Database has been built up by collecting earthquake, flood and other natural disaster loss data for quite a few years since 2003 at the University of Adelaide, with a more concerted effort in the past 3 to 4 years to build up the databases further. This report in 2011 only shows a small percentage of the data collected but a new and exciting future in earthquake reporting. In the last 12 months, we have reported constantly on www.earthquake-report.com, founded by Armand Vervaeck, and worked tirelessly to provide the best quality scientific reporting of felt earthquake and volcanic events worldwide and CATDAT to provide detailed accounts on every damaging earthquake worldwide.

The purpose of this report is to present the damaging earthquakes in the year 2011 around the world that were entered into the CATDAT Damaging Earthquake Database in terms of their socio-economic effects. This 2011 report showcases the work that CATDAT, in collaboration with earthquake-report.com / SOS Earthquakes, is doing.
