Magnitude 6.3 Earthquake Strikes off Sumatra Island, Indonesia

A shallow-undersea earthquake with a magnitude of 6.3 jolted Sumatra island earlier Sunday, however, suggested no potential danger of a tsunami, Xinhua quoted the Meteorology and Geophysics Agency as saying.

The quake, which struck at 00.07 a.m. (Jakarta time) Sunday (1707 GMT Saturday), had its epicentre at 119 km southwest Krui of Lampung province and a depth at 10 km under sea bed, an official of the agency stated.


US: 1.7 Magnitude Quake Caused Rumbling In Philadelphia Area

Philadelphia residents who were shocked to feel their homes shake from what they thought was an explosion learned Saturday that a minor earthquake had struck the area.

An earthquake registering magnitude 1.7 struck the Philadelphia area Friday night, the US Geological Service (USGS) said Saturday.

The quake struck at 9:33pm local time Friday in northeastern Philadelphia at a shallow depth of 2.6 miles (4.2 kilometers).

The USGS initially said it had no seismological evidence of an earthquake or tremor as officials had no explanation earlier Saturday for residents who felt their homes rumble, The Philadelphia Inquirer reported.

Police, firefighters and other emergency responders were dispatched to the area after hundreds of residents reported feeling the ground shake shortly before 10:00pm.

Japan's 11 March mega-quake shifted the ocean floor sideways by more than 20m

Japan's 11 March mega-quake shifted the ocean floor sideways by more than 20m (65ft), according one instrument placed on the seabed off the nation's coast. This direct measurement exceeds the displacement suggested by some models built only from data gathered on land.

The figure was recorded by the Japan Coast Guard which maintains underwater geodetic equipment along the fault responsible for the giant tremor. An upwards movement of 3m (10ft) was registered by the same instrument. The data underlines once again the colossal nature of the Magnitude 9.0 quake and its associated tsunami.

The scale is almost double that estimated only from the terrestrial data. Results show how important offshore data are to know where and to what extent the rupture occurred on the plate boundary.

Volcano erupts in Iceland, spurs 50 quakes

White plume shoots 18,000 feet above the glacier that sits over the volcano

Grimsvotn volcano
Reykjavik, Iceland - Iceland's most active volcano erupted Saturday, with a white plume shooting 18,000 feet into the air, scientists said.

The eruption was followed by around 50 small earthquakes, the largest of which measured 3.7 on the Richter Scale, according to Iceland's meteorological office.

There was a similar eruption at the same volcano in 2004.

Scientists don't believe this eruption will lead to air travel chaos like that caused by ash from the Eyjafjallajokul volcano in April 2010.

The Grimsvotn volcano is located underneath the Vatnajokull glacier in southeast Iceland.

Sparsely populated Iceland is one of the world's most volcanically active countries and eruptions are frequent.

They often cause local flooding from melting glacier ice, but rarely cause deaths.

Last year's Eyjafjallajokul eruption left millions of air travelers stranded after winds pushed the ash cloud toward some of the world's busiest airspace and led most northern European countries to ground all planes for five days.

In November, melted glacial ice began pouring from, signaling a possible eruption. That was a false alarm but scientists have been monitoring the volcano closely ever since.

Frequency of Tremors on the Rise in Guerrero

Acapulco,- So far in the month of May, 60 tremors have been registered in Guerrero, mostly in the Richter range of 3 or 4. Monday afternoon a tremor of 4.3 was felt and an earlier one of 5.5 was registered on May 5 with the same epicenter, in the municipality of Ometepec, in the Costa Chica, to the east and south of Acapulco. More than one-third of the tremors taking place in this month in Guerrero have had their origin in the Costa Chica.

Five tremor epicenters have occurred within the municipality of Acapulco since May 1, all of them between 3 and 4 on the Richter scale. The tremors felt in Guerrero in the first two weeks of May is double the number registered for the same period last year.
