Another small earthquake has been reported in Oklahoma.

The U.S. Geological Survey says a 3.2 magnitude quake struck just before 6 a.m. Sunday about 27 miles northeast of Oklahoma City. The Logan County Sheriff's Office says no damage was reported

On Saturday, a 2.4 magnitude tremor was recorded at about 7 a.m. about 50 miles northeast of Oklahoma City near Sparks.

Sunday's earthquake is the sixth in the area since Thursday, when a 3.7 magnitude quake was recorded near Prague. Three more were recorded Friday.

A 5.6 magnitude quake, the strongest ever recorded in Oklahoma, shook the state Nov. 5. That quake damaged dozens of homes, buckled a highway and caused other damage.

Geologists say earthquakes with magnitudes of 2.5 to 3.0 are generally the smallest felt by humans.

San Salvador: More than 700 slight to moderate earthquakes hit an area in eastern El Salvador in a 24-hour period, damaging dozens of homes but hurting no one.

The brief quakes, which started Thursday and ranged from 1.8 to 4.6 in magnitude, have occurred in the municipality of El Carmen, some 163 km (101 miles) east of the capital of San Salvador, the country's National Territory agency said.

Jorge Melendez, in charge of civil protection, said on Friday that 80 homes were damaged by the tremors, known as an earthquake swarm. A hospital in the area showed cracks on the walls but no structural damage so far, he said.

Army troops were sent in to monitor the damaged areas. While authorities have not ordered evacuations yet, many residents of El Carmen chose to sleep in the open and the army was handing out tents.

El Salvador suffered two powerful earthquakes 10 any ten years ago: one of 7.6 magnitude in January 2001 and another of 6.6 magnitude a month later. The quakes killed more than 1,150 people and left about one million others homeless.

Second Earthquake of Day Shakes Northern Japan

Tokyo - Two strong earthquakes rattled northern Japan on Thursday, but neither caused any apparent damage or a tsunami.

A magnitude-6.1 quake struck Thursday evening south of the northern island of Hokkaido, Japan's Meteorological Agency said.

It hit about 465 miles (750 kilometers) northeast of Tokyo and 19 miles (30 kilometers) below the sea surface. The agency did not issue a tsunami warning.

About 3,900 households in the towns of Erimo and Samani lost electricity shortly after the quake, but power was restored about an hour later, according to the Hokkaido Electric Power Co.

The shaking was not felt in Tokyo, though a morning quake was.

That magnitude-6.0 temblor struck just off the coast near the nuclear power plant damaged by the March 11 earthquake and tsunami.

The two shakings are believed unrelated and did not affect the crippled Fukushima Dai-ichi plant or other nuclear plants in the region.

Sun, 20 Nov 2011 23:18 UTC

Guwahati: An earthquake measuring 5.9 on the Richter scale rocked India's northeast, Myanmar and Bangladesh on Monday, triggering panic among people.

The tremor was felt at 8.47am in most parts of Assam, Nagaland, and Manipur, besides in Bangladesh and Myanmar.

The epicentre was located at 24.947°N, 95.226°E in Myanmar, about 130 km east of Manipur capital Imphal, the website of US Geological Survey said.

Seven northeastern states - Assam, Meghalaya, Mizoram, Tripura, Nagaland, Arunachal Pradesh and Manipur - are considered by seismologists to be the sixth most earthquake-prone belt in the world.

The region experienced one of the worst earthquakes, measuring 8.7 on the Richter scale, in 1897, that claimed the lives of over 1,600 people.

In September, more than 50 people died after a killer quake measuring 6.8 on the Richter scale shook the region.

India: Tremors Cause Cracks in Kerala Dam

Fri, 18 Nov 2011 23:09 UTC

Small cracks appeared at least at three points in the 115-year-old Mullaperiyar dam in Kerala's Idukki district following two minor tremors that occurred early on Friday.

The tremors and cracks have created panic among the people in River Periyar's downstream areas. The district has more than a dozen large and medium-sized dams including Asia's largest arch dam, Idukki.

Officials of the Kerala Water Resources Department said the cracks had appeared in Block 17 and the joint of Block 17 and 18 following the tremors. The tremors also caused water seepage through the cracks from the Mullaperiyar reservoir, situated on the Kerala-Tamil Nadu border. Officials said the cracks were no serious enough to cause panic.
