A series of tremors along with underground explosions that were heard from above and caused walls to crack occurred yesterday in the area of the Song Tranh 2 Hydropower Plant in Quang Nam Province's Bac Tra My District.

Experts at the plant are analyzing data collected from earthquake observation stations in the area but have yet to announce how powerful the quake was on the Richter scale, said Tran Van Hai, head of the Management Board of Hydropower Project 3.

The incident happened from 7 to 9 pm Monday at the Bac Tra My Town and several communes nearby, causing thousands of locals to rush out of their houses in panic after they heard loud blasts and found the ground shaken, houses' walls cracked and things inside the houses falling.

Ho Van Loi, chairman of the Tra Doc commune People's Committee said his house's floor was shaken five times during last night, with the most powerful seismic intensity occurring at 9 pm.

Quake off Philippines spurs small tsunami; 1 dead

A 7.6-magnitude quake struck off the eastern coast of the Philippines late Friday, killing at least one person in a house collapse, knocking out power in several towns and generating negligible tsunami surges.

A tsunami alert originally was issued for several countries in the region including Indonesia and Japan and for Pacific islands as far away as the Northern Marianas, but they all were later lifted, the Pacific Tsunami Warning Center said.

The center said that very small tsunami waves of 3 centimeters meters (just over an inch) were recorded along the eastern Philippine coast near Legazpi city and another nearby location.

Benito Ramos, a retired general who heads the country's disaster-response agency, said in an advisory broadcast nationwide that residents should be on the alert for aftershocks.

Earthquakes Raise Alert Level at Alaska Volcano

A series of small earthquakes which began Wednesday night and continued into Thursday near a long-dormant volcanic peak in Alaska's Aleutian Islands has prompted researchers to raise the alert level for the Little Sitkin volcano.

The nearly 4,000-foot-high Little Sitkin volcano is named for the island where it resides, located in the Rat Islands in the Aleutian chain. The volcano has shown little activity since scientists have started observing it, with only three questionable eruptive events at the volcano since that time.

The most recent eruption may have come in 1900, according to the Alaska Volcano Observatory.

Still, the AVO page for Little Sitkin mentions there may have been a "cataclysmic eruption" on the island sometime after the last ice age, which ended more than 11,000 years ago.

Seismic equipment located near the volcano began detecting a "swarm of high-frequency earthquakes" at about 7:15 p.m. Wednesday, the AVO reports. The earthquakes continued through the night into Thursday, prompting the alert level at the volcano being raised. The alert level is currently at yellow, which means that the "volcano is exhibiting signs of elevated unrest above known background level." Additionally, aircraft traveling in the area are advised to exercise caution.

The volcano is located in a remote part of the Aleutians, about 35 miles northwest of the World War II outpost of Amchitka and 200 miles west of Adak.

Little Sitkin joins two other Alaska volcanoes, Iliamna and Cleveland, currently sitting at elevated alert levels.

Earthquake clusters detected at remote Aleutian volcano

Thu, 30 Aug 2012 14:53 UTC
Seismologists say a cluster of earthquakes has been detected at a remote volcano in Alaska's western Aleutian Islands. The Alaska Volcano Observatory says the quakes began Wednesday evening at Little Sitkin Volcano and are continuing as of Thursday morning. No eruption has been detected.

Scientist in charge John Power says there is no direct link to the swarm of earthquakes at Little Sitkin and a cluster of quakes that shook California's Imperial County this week.

Powers says Little Sitkin is on an uninhabited island and is far from any populated areas. He says the seismic activity is unusual for Little Sitkin, which may have last erupted in the early 1900s.

Powers says the concern about an eruption would be the possible threat posed to aircraft by airborne ash.

Canada, British Columbia - A 3.0-magnitude earthquake, described as minor by local experts, caused some shaking in Greater Victoria but no recorded damageWednesday afternoon.

Seismologist Garry Rogers from the Pacific Geoscience Centre said the quake hit at 3:20 p.m. and was concentrated about 10 kilometres northwest of Colwood, toward Sooke Lake.

The earthquake came from about 25 kilometres underground.

"It was felt pretty much throughout the area," Rogers said. "We got reports from Sidney to Sooke to all over Greater Victoria." A 3.0-magnitude earthquake, described as minor by local experts, caused some shaking in Greater Victoria but no recorded damage Wednesday afternoon.
