No tsunami threat from strong quake in Gulf of Alaska

A strong earthquake in the Gulf of Alaska this morning did not generate a tsunami, officials said.

The quake, which struck at 10:42 a.m., had a magnitude of 6.4 and was centered 349 miles southeast of Anchorage at a depth of 34 miles, according to the U.S. Geological Survey.

The Pacific Tsunami Warning Center in Ewa Beach said there was no tsunami threat. The West Coast and Alaska Tsunami Warning Center also said there was no threat to that region.

There were no reports of damage despite tremors being felt across a large part of southern Alaska. A series of aftershocks also were recorded.

Natasha Ruppert, a seismologist with the Alaska Earthquake Information Center, said this was the largest earthquake in the region since 1987 and 1988, when quakes of magnitude 7.8 and 7.7, respectively, struck.

Strong quake strikes Northern Myanmar, 12 feared dead

A strong earthquake collapsed a bridge and damaged ancient Buddhist pagodas in northern Myanmar, and piecemeal reports from the underdeveloped mining region said mines collapsed and as many as 12 people were feared dead.

Myanmar's Vice President Sai Mauk Hkam visited the damaged sites Monday, while authorities resumed their search for four missing workers near the collapsed bridge over the Irrawaddy River in Kyaukmyaung.

A slow release of official information left the actual extent of the damage unclear after Sunday morning's magnitude-6.8 quake. Myanmar has a poor official disaster response system and lost upward of 140,000 people to a devastating cyclone in 2008.

"We have been told by the director of Relief and Resettlement Department that there were seven dead and 45 injured as of late Sunday evening. The figure could fluctuate," said Ashok Nigam, the U.N. development program's resident representative. He told The Associated Press that U.N. agencies had offered aid but "no formal request has been made yet."

Myanmar's second-biggest city of Mandalay is the nearest population center to the main quake but reported no casualties or major damage. Mandalay lies about 117 kilometers (72 miles) south of the epicenter near the town of Shwebo, and the smaller towns in the area that is a center for mining of minerals and gemstones were worse hit.

'Roaring' earthquake rattles Madison County, Kentucky residents

Residents in Madison County and throughout eastern and central Kentucky got a lunchtime scare when an earthquake rattled through the area.The 4.3-magnitude earthquake happened at 12:08 p.m. Saturday, according to the U.S. Geological Service. The epicenter was about 8 miles west of Whitesburg.

Madison County Emergency Management Agency Director Carl Richards said there were no reports of damage or calls for assistance in the county following the temblor. Some people did call 911 wondering what was happening, he added.Richards noted that people who were inside noticed the shaking more than those who were outside, like himself, when the earthquake struck. Also, people in the southern end of the county reported feeling the earthquake's affects more.

"I not only felt the whole house shake but also heard a 'roar' of some sort ... my dishes were rattling, light fixtures were shaking, and floors and walls were vibrating," reported Dawn Agee Truett, of Berea, on the Register's Facebook page shortly after the quake. "... Definitely a very strange feeling!"

"Felt a nice rattle in north Richmond!" Jacqulyn Howell also commented.

Dozens of local residents related stories of their pets acting strangely and their houses being shaken for about 10 to 30 seconds.

British Columiba earthquake dried up centuries-old Haida Gwaii hot springs

B.C. hot springs

Canada - Days after the remote B.C. archipelago of Haida Gwaii emerged virtually unscathed from Canada's second-strongest earthquake, locals discovered that the shifting earth had mysteriously switched off a centuries-old hot spring considered sacred by the Haida.

"It's a very culturally significant site - even today Haida people would go down to take advantage of healing properties of the springs," said Ernie Gladstone, a field unit superintendent for Gwaii Haanas National Park, of which Hot Spring Island is a part.

Earlier this week, scattered reports began drifting in that the familiar cloud of steam over the island (known as Gandll K'in Gwaayaay in the Haida language) had disappeared.

A Parks Canada inspection party set out to investigate and stepped ashore to find that the island's three main hot spring pools, which once bubbled with water as warm as 77 Celsius, were bone dry. "Not even a small puddle," said Mr. Gladstone.

Surrounding rocks, once warm to the touch, were cold.

Earthquakes on East Coast travel farther and cause more damage due to geologic structure and rock properties

Data from the 2011 earthquake centered in Virginia shows East Coast tremors can travel much farther and cause damage over larger areas than previously thought, the U.S. Geological Survey said Tuesday.

The agency estimated about one-third of the U.S. population could have felt the magnitude 5.8 tremor centered about 50 miles northwest of Richmond, which would mean more people were affected than any earthquake in U.S. history. Scientists also found the quake that caused more than $200 million in damage triggered landslides at distances four times farther and over an area 20 times larger than research from previous quakes has shown.

"Scientists are confirming with empirical data what more than 50 million people in the eastern U.S. experienced firsthand: this was one powerful earthquake," USGS Director Marcia McNutt said in a news release about the findings presented at the Geological Society of America conference in Charlotte, N.C.
