A deep, magnitude-6.1 earthquake shook people awake in Peru's central jungle region early Thursday and was also felt in the capital, Lima. There were no immediate reports of damage or injuries. Civil defense official Jairo Goreau in the provincial capital of Pucallpa near the epicenter said some power outages were reported as well as telephone line congestion but city inspectors had so far encountered no damage.

The quake struck at 4:38 a.m. (9:38 GMT), 21 miles (34 kilometers) east of Pucallpa, a city of more than 270,000 people, at a depth of 89 miles (143 kilometers), according to the U.S. Geological Survey.

A new study published in the prestigious journal Science, co-authored by University of Nevada, Reno's Glenn Biasi and colleagues at GNS Science in New Zealand, finds that very large earthquakes have been occurring relatively regularly on the Alpine Fault along the southwest coastline of New Zealand for at least 8,000 years.

The Alpine Fault is the most hazardous fault on the South Island of New Zealand, and about 80 miles northwest of the South Island's main city of Christchurch.

The team developed evidence for 22 earthquakes at the Hokuri Creek site, which, with two additional from nearby, led to the longest continuous earthquake record in the world for a major plate boundary fault.

The team established that the Alpine Fault causes, on average, earthquakes of around a magnitude 8 every 330 years. Previous data put the intervals at about 485 years.

Relative motion of Australian and Pacific plates across the Alpine Fault averages almost an inch per year. This motion builds up, and then is released suddenly in large earthquakes.

Earthquake east of Grímsey Island

Earthquake with the magnitude of ML3.5 (estimate) did take place at 19:48 UTC. This is normal tectonic activity for this area. But this area of Iceland has the most earthquake activity most of the year.

An earthquake of moderate intensity shook Meghalaya, Assam and some other north-east states today but there was no report of any casualty or damage to property. The quake, which had a magnitude of 6.0 on the Richter scale, hit the region at around 7:51 am and the epicentre was located 70 km underneath the earth's crust in Myanmar, officials at the Seismological Survey of India said.

The officials said the quake was of "moderate" intensity and all major towns in the region felt the tremor.

Earlier this month, tremor having a magnitude of 5.4 and 5.5 on the Richter Scale hit the region with their epicentres located in Phek and Nagaland region of Nagaland respectively.

Sunday's tremor was also felt in Itanagar, Guwahati, Agartala besides Kohima and Imphal.

Police said there was no report of any casualty or damage to property in Meghalaya.

A strong earthquake struck off the coast of Papua New guinea in the South Pacific but did not generate a Pacific-wide tsunami, officials said this morning.

The magnitude 6.6 quake struck 19 miles south-southeast of Taron, Papua New Guinea at a depth of more than 40 miles about 6:04 a.m. Sunday (10:04 a.m. Saturday, Hawaii time), according to the U.S. Geological Survey.

The Pacific Tsunami Warning Center in Ewa Beach said that while no Pacific-wide tsunami was generated, earthquakes of this size can produce locally destructive tsunamis near the epicenter.

A strong earthquake with a magnitude of 6.6 struck off northern Sumatra in Indonesia on Wednesday, the U.S. Geological Survey said, but authorities said there was little chance of a tsunami.

The quake was felt by residents on the island of Simeulue off Sumatra's northwest coast but there were no
immediate reports of damage or injuries.

"The quake has no tsunami potential," said Sutopo Purwo Nugroho, a spokesman for the National Disaster Mitigation Agency. "Some people ran away from their houses. We don't have any house damage."

The Hawaii-based Pacific Tsunami Warning Center said there was no threat of a widespread, destructive tsunami after the quake, about 330 km (205 miles) southeast of Indonesia's Banda Aceh. It said there was a "very small possibility" of a local tsunami.

A magnitude-5.2 earthquake rocked southern Mexico early Tuesday, but there are no damage or injury reports, the U.S. Geological Survey, or USGS, said.

The quake's epicenter, which was located at a depth of 13.2 kilometers (8.2 miles), was 11 kilometers (6.8 miles) south-southeast of San Juan de Cacahuatepec, a town in Oaxaca state, and 24 kilometers (14.9 miles) north of Santiago Pinotepa Nacional, another town on the southern state's Pacific coast.

The earthquake occurred at 12:25 a.m, the USGS said.

Mexico's National Seismological Service confirmed the temblor on its Twitter and estimated the magnitude at 5.62.

The earthquake was felt in Mexico City, but officials have not reported any injuries or damage, media outlets said.

A magnitude-7.4 earthquake on March 20 killed two people in southern Mexico and was followed by dozens of strong aftershocks.

On April 2, a magnitude-6.0 earthquake rocked an area between the southern states of Guerrero and Oaxaca.

Mexico, one of the countries with the highest levels of seismic activity in the world, sits on the North American tectonic plate and is surrounded by three other plates in the Pacific: the Rivera microplate, at the mouth of the Gulf of California; the Pacific plate; and the Cocos plate.

That last tectonic plate stretches from Colima state south and has the potential to cause the most damage since it affects Mexico City, which has a population of 20 million and was constructed over what was once Lake Texcoco.

The magnitude-8.1 earthquake that hit Mexico City on Sept. 19, 1985, was the most destructive to ever hit Mexico, killing some 10,000 people, injuring more than 40,000 others and leaving 80,000 people homeless.

The most recent powerful quake to hit Mexico was a magnitude-7.6 temblor that rocked Colima on Jan. 21, 2003.
