A minor, 3.9 magnitude earthquake was confirmed Tuesday morning off the coast of Long Island.

According to the U.S. Geological Survey, the quake occurred just over 80-miles from Southampton and 122 miles southeast of New York City. A handful of East End residents, from East Hampton to Southampton have reported feeling the quake, which a dispatcher from Southampton Town Police said shook police headquarters in Hampton Bays for seven seconds.

No injuries or damages have been reported as a result of the quake.

At least nine volcanic quakes were recorded near restive Bulusan Volcano in Bicol in the last 24 hours, national disaster management officials said Tuesday.

The National Disaster Risk Reduction and Management Council (NDRRMC) also reported weak emission of white steam from the volcano's northwest thermal vents.

"For the past 24-hour observation period, Bulusan Volcano's seismic network detected nine volcanic quakes. Measurement of sulfur dioxide emission rate yielded an average value of 36.56 tons per day. Weak emission of white steam was observed from the northwest thermal vents from 8:35 to 10:35 a.m. (Monday)," the NDRRMC said in its 8 a.m. bulletin.

US: 21 earthquakes strike Reno over 3 days

An area southwest of downtown Reno has been shaking with earthquakes.

According to the U.S. Geological Survey, 21 temblors were reported in the area since midday Friday.

The latest measured 2.1 in magnitude and was reported at 10:22 a.m. Monday.

The largest measuring 3.0 came at 1:47 a.m. Sunday and was felt throughout the Reno area.

Ken Smith is a seismologist with the University of Nevada, Reno.

He tells the Reno Gazette-Journal that the area of quake activity is about 5 miles west of the intersection of U.S. 395 and the Mount Rose Highway.

In 2008, a cluster of more than 1,000 small earthquakes shook the region for three months before subsiding.

Philippines: 'Explosion-type' earthquake reported at Bulusan Volcano

Bulusan Volcano
Legazpi City -- An "explosion-type" earthquake was recorded by the Philippine Institute of Volcanology and Seismology in in Sorsogon Friday night.

In its latest bulletin, Phivolcs said that the quake occurred at around 7:27 p.m. and lasted for about 11 minutes. Clouds, however, prevented state volcanologists to visually observe it.

The statement did not say what distinguished an "explosion-type" earthquake from any other volcanic tremor.

Sulfur dioxide emission rate was measured at 13 tons per day.

About 11 volcanic quakes were also recorded by the seismic network around the volcano during the past 24-hour observation period.

Phivolcs said Bulusan's status remained at alert level 1 and the public was reminded not to venture into the four-kilometer permanent danger zone as sudden steam and ash explosions may occur.

Strong Earthquake Hits Near Eastern Taiwan Coast

Strong Earthquake Hits Near Eastern Taiwan Coast; No Damage Reported

Officials say a strong earthquake has struck near the eastern coast of Taiwan. No casualties or damage have been reported.

Taiwan's Central Weather Bureau says the earthquake hit Sunday evening and was centered 13 miles (22 kilometers) from Hualien county, and about 85 miles (135 kilometers) southeast of Taipei. It says the quake registered magnitude 6.1, while the U.S. Geological Survey measured it at 5.6.

Earthquakes frequently hit Taiwan but most are minor and cause little or no damage.

Underneath Haiti, Another Big Quake Waiting to Occur

Haiti Earthquake

A day after the earthquake, a young woman climbs over shopping carts and the rubble of a collapsed store on January 13, 2010 in Port-au-Prince, Haiti.
Last week, on the morning of Nov. 11, a tremor shook the Port-au-Prince suburb of Carrefour. It was a minor geological event, but given the still fresh and haunting memories of the 7.0-magnitude earthquake that hammered Haiti on Jan. 12 and killed some 230,000 people - many of them in Carrefour - even that mild shudder caused public panic. The only reported injuries, in fact, were due to people scrambling to take cover.

To geologists, it's good to see Haitians on such heightened alert. Most scientists believe the western hemisphere's poorest country is hardly out of the seismic woods - and after studying the Haiti quake data for the past 10 months, they're more convinced than ever that Haitians can expect another major quake sooner rather than later. That's largely because they've found, according to a new study by 10 prominent geologists, that the lion's share of the January temblor occurred not along the fault line they originally suspected, known as the Enriquillo - Plantain Garden fault zone, but on a previously unknown fault. (Faults separate plates in the earth's crust, which cause quakes when stress makes them collide.) As a result, says Falk Amelung, a University of Miami geologist and one of the report's authors, "the prospects of another serious event may be rather worse than we first thought."

When Amelung and other geologists started poring over information from the earthquake's satellite-radar images last January, they were flummoxed by a variety of features. One was the vertical motion the quake exhibited - unusual because the Enriquillo, which runs across Haiti's southern peninsula just below Port-au-Prince, is a strike-slip fault, the kind that almost exclusively displays horizontal motion when it ruptures. At the same time, the quake's horizontal movement was partly north-south, another anomaly for a strike-slip fault. "Those were the two important smoking guns" that made scientists question their early assumptions about the quake, says Eric Calais, a Purdue University geologist who is in Haiti as a science adviser to the U.N. Development Program and is a lead author of the study, which was published last month in Nature Geoscience.(See more about the January earthquake that devastated Haiti.)
