Huge Japan Quake Cracked Open Seafloor

Cracked Seafloor
© Norio Miyamoto, JAMSTEC This 8-inch-wide (20 cm) crevasse stretches for at least tens of meters in a north-south direction; its depth is unknown. The crack, at a depth beneath the water's surface of 10, 558 feet (3,218 m) was imaged on Aug. 10, 2011.
The March 2011 megaquake off the coast of Japan opened up fissures as wide as 6 feet (3 meters) in the seafloor, a new study finds.

The fissures now scar the seafloor where peaceful clam beds once lay, according to Takeshi Tsuji, a researcher at Kyoto University in Japan. Along with seismic studies, the fissures, revealed by manned submersible vehicles that investigated the seafloor after the quake, show how the crust around the quake's epicenter expanded and cracked.

Tsuji and his colleagues had a unique opportunity to see how the seafloor changed after the magnitude-9.0 quake struck on March 11. Before the quake, the researchers had taken video and photographs of the seafloor on the continental side of the Japan Trench, near where the crust would later rupture, generating an enormous tsunami that killed about 20,000 people.

Those videos showed a quiet seafloor broken only by occasional clam beds, Tsuji reported here today (Dec. 6) at the annual meeting of the American Geophysical Union (AGU). After the quake, however, the seabed shows evidence of the massive forces released there.

Mountain explodes violently in Vietnam as earth cracks- scientist warn of a coming quake

About 50km from Quang Nam province's administrative center is Tam Ky City. It takes over three hours for a motorbike to make it down the bumpy road DT616 crossing mountains and hills from there to Bac Tra My Town, where strange geologic activity has residents on edge

Increasingly violent mountain explosions

Residents of the town cannot help but feel anxious, as the intensity of the quakes keeps increasing. The nearby mountain of the Truong Son chain explodes ever more loudly every night.

Lu Quang Lai, nearly 70, says he has never witnessed such strange phenomenon in Tra My in the past decades.

"About 10 months ago, when the new hydroelectricity power plant started to conserve water, the water level in the lake got higher every day. The land here seemed to change. Every night exploding sounds would emanate from the earth, followed by a rumbling sound. Recently the explosions and quakes have become more violent. Glasses and cups fall down like leaves, everything tilts", Lai speaks in a tremble.

Nguyen Phuoc Danh, a motorbike mechanic, lives in a house 300km from Song Tranh 2 hydroelectricity plant's dam. His home is the worst affected in the area, suffering from three tremors.

"Two nights ago, the mountain exploded with a deafening sound. Although I've become used to the noise caused by TNT explosives during the dam's construction, nothing compared to the recent explosion.

"A few seconds later, the earth shook. The roof and the windows rattled. Things started to fall. The wall creaked, and then cracked. I took my wife and kids out to the street. A chill crept up from my heels to my head just like electricity", Danh says in disbelief.

Two small earthquakes have shaken central Oklahoma.

The U.S. Geological Survey says both earthquakes were centered in Lincoln County and recorded between 10:42 p.m. and 11:05 p.m. Friday.

The first 2.7 magnitude earthquake was recorded about six miles west northwest of Prague. The second was a 2.3 magnitude tremor whose epicenter was five miles south southeast of Sparks and seven miles northeast of Meeker. No injuries were reported.

A loud bang was also heard by eyewitnesses and buildings shook.Quakes of this intensity are more common in the North of the country with the South being relatively calm.

5.8 magnitude quake hits Nicobar Islands

A moderate earthquake measuring 5.8 on the Richter scale jolted Nicobar Islands early on Thursday.

The quake hit the islands at 1.12 a.m., Xinhua quoted the U.S. Geological Survey (USGS) as saying.

The quake's epicentre, with a depth of 1.00 km, was initially determined to be at 7.8365 degrees north latitude and 94.0158 degrees east longitude.

Earthquake rocks north Philippines; no damages

Manila, - An official says an earthquake with a magnitude of 6 shook the capital and parts of the northern Philippines. There are no immediate reports of damages or injuries.

Philippine Institute of Volcanology and Seismology chief Renato Solidum says movement in the Manila Trench off the country's western coast set off the earthquake Wednesday but it occurred deep under the ocean floor and did not cause any destruction.

Solidum says the quake was felt in metropolitan Manila and in the nearby provinces of Zambales, Bulacan, Pangasinan and in the mountain resort city of Baguio.

The Philippines is located in the Pacific "Ring of Fire" where earthquakes and volcanic activity are common. A 7.7-magnitude quake killed nearly 2,000 people in Luzon in 1990.

Another small earthquake has been reported in Oklahoma.

The U.S. Geological Survey says a 3.2 magnitude quake struck just before 6 a.m. Sunday about 27 miles northeast of Oklahoma City. The Logan County Sheriff's Office says no damage was reported

On Saturday, a 2.4 magnitude tremor was recorded at about 7 a.m. about 50 miles northeast of Oklahoma City near Sparks.

Sunday's earthquake is the sixth in the area since Thursday, when a 3.7 magnitude quake was recorded near Prague. Three more were recorded Friday.

A 5.6 magnitude quake, the strongest ever recorded in Oklahoma, shook the state Nov. 5. That quake damaged dozens of homes, buckled a highway and caused other damage.

Geologists say earthquakes with magnitudes of 2.5 to 3.0 are generally the smallest felt by humans.
