SANTIAGO (Reuters) – Chile’s navy says a tsunami has already hit some areas in the north of the country following a massive earthquake offshore.
The earthquake, of magnitude 8.0, struck off the coast of Chile on Tuesday, sparking a tsunami warning for all of South and Central America’s Pacific coast, the Pacific Tsunami Warning Center said. source – Yahoo News
LA Times: Authorities were tallying damage from a magnitude 5.1 earthquake that struck Southern California on Friday night. Fullerton police said early Saturday that up to 50 people had been displaced because of home damage.
The quake, centered near La Habra, caused furniture to tumble, pictures to fall off walls and glass to break. Merchandise fell off store shelves, and there were reports of plate glass windows shattered.
In Brea, several people suffered minor injuries during a rock slide that overturned their car. Fullerton reported seven water main breaks. Carbon Canyon Road was closed.
Residents across Orange and Los Angeles counties and the Inland Empire reported swinging chandeliers, fireplaces dislodging from walls and lots of rattled nerves. The shake caused a rock slide in Carbon Canyon, causing a car to overturn, according to the Brea Police Department. Fullerton police received reports of water main breaks and windows shattering, but primarily had residents calling about burglar alarms being set off by the quake.
Third-grade teacher Barbara Castillo and her 7-year-old son had just calmed their nerves after an earlier 3.6 temblor and sat down in their La Habra home when their dogs started barking and the second, larger quake struck, causing cabinet doors to swing open, objects to fall off shelves and lights to flicker.
“It just would not stop, it was like an eternity,” said Castillo, an 18-year La Habra resident.
At Disneyland in Anaheim, all rides were halted as a precaution but no damage or injuries were reported — other than ceiling tiles falling in the police station, Sgt. Daron Wyatt said.
The first of a swarm of earthquakes hit the border of La Habra and Brea shortly after 8 p.m. with the 3.6 temblor. About an hour later, at 9:09 p.m., the 5.1 shock hit, followed by at least two more aftershocks in the magnitude-3 range in the next half hour. At least 20 aftershocks had been recorded by late Friday.
U.S. Geological Survey seismologist Lucy Jones said the 5.1 quake has a 5% chance of being a foreshock of a larger temblor.
“There could be even a larger earthquake in the next few hours or the next few days,” Jones said during a media briefing at Caltech.
Experts said that based on preliminary data, the series of earthquakes appeared to have occurred on the Puente Hills thrust fault, which stretches from the San Gabriel Valley to downtown Los Angeles. The fault also caused the 1987 Whittier Narrows earthquake.
Friday night’s 5.1 quake was relatively shallow, which “means the shaking is very concentrated in a small area,” said Caltech seismologist Egill Hauksson. Hauksson said the quake sequence was unusual in that the 5.1 quake was preceded by the weaker foreshock.
Scientists are particularly concerned about the Puente Hills thrust fault because it goes directly underneath downtown Los Angeles. “This is the fault that could eat L.A.,” seismologist Sue Hough told The Times in 2003.
On Friday, though, police and fire departments in Los Angeles reported no damage. “Tonight’s earthquake is the second in two weeks, and reminds us to be prepared,” Los Angeles Mayor Eric Garcetti said in a statement.
Although the shaking was felt throughout the region, it didn’t rattle the professionalism at Walt Disney Concert Hall. Microphones above the stage swung back and forth and the hall shook, but the orchestra continued playing.
“The L.A. Philharmonic should get combat pay,” said audience member Michael Healy of Studio City. source – LA Times
Manila: An earthquake measuring 7.9 on the Richter Scale rocked the coast of Philippines on Friday. Following the earthquake, tsunami warnings were issued for Philippines, Indonesia, Taiwan and Japan.
Tsunami alerts were also issued for Papua New Guinea and other islands in the Pacific, including the US state of Hawaii.
The quake was centered off the east coast, 91 miles off the town of Guiuan in Samar province, the US Geological Survey said. source – IBN
Jakarta, Indonesia (CNN) – A massive earthquake struck off the coast of the Indonesian island of Sumatra on Wednesday afternoon, triggering a tsunami alert for the Indian Ocean.
The quake struck about 434 kilometers (270 miles) southwest of Banda Aceh, the capital of Indonesia’s Aceh province, and had a magnitude of 8.6, the U.S. Geological Survey said. It took place at a depth of 23 kilometers (14 miles).
A second quake, magnitude 8.2, occurred off the west coast of Sumatra about two hours later, the USGS said.
Gary Gibson from the Seismology Research Center in Melbourne, Australia, said the location of the second quake reduces the possibility of a tsunami.
There were no immediate reports of destruction or deaths Wednesday.
Indonesian President Susilo Bambang Yudhoyono said on local television that there were no reports of casualties or damage in Aceh.
The Pacific Tsunami Warning Center issued a tsunami watch for the entire Indian Ocean, and the Indonesian Meteorology, Climatology and Geophysics Agency said it had put up a tsunami warning as well.
Sea level readings indicate a tsunami was generated, the warning center said. “It may already have been destructive along some coasts.”
The center also said that “when no major waves have occurred for at least two hours after the estimated arrival time or damaging waves have not occurred for at least two hours, then local authorities can assume the threat is passed.” The center posted approximate arrival times for waves in different parts of the region, which were predicted for different times in different cities throughout the day.
Waves were reported at 1-meter (3.3-foot) amplitude offshore in Meulaboh, Indonesia, but in other cities they were reported at about a foot or less, according to the warning center.
British Prime Minister David Cameron announced that Britain “stands ready to help if required.”
The first quake took place at 2:38 p.m. local time (4:38 a.m. ET). Officials called on coastal residents in low-lying areas in the region to seek higher ground.
The power went out in Banda Aceh and residents were moving to higher ground, said Sutopo Purwo Nugroho, a spokesman for the Indonesian National Disaster Management Agency. The areas most at risk of a tsunami are coastal areas of Aceh, particularly the island of Simeulue, Prih Harjadi, an official for the Indonesian geophysics agency said on Metro TV. source – CNN
TOKYO — An earthquake with a preliminary magnitude of 6.1 hit east of Tokyo on Wednesday but no tsunami warning was issued and there were no initial reports of damage or troubles at area nuclear plants, the Japan Meteorological Agency and local media said.
The earthquake, which caused substantial shaking in Ibaragi and Chiba prefectures east of Tokyo, followed just a few hours after a magnitude 6.8 quake jolted northern Japan.
A tsunami warning was issued but later lifted after the northern Japan earthquake. Just over one year ago, the northeast coast was struck by a magnitude 9 earthquake, Japan’s strongest on record, and a massive tsunami, triggering the world’s. source – MSNBC
TEHRAN (Reuters) – About 100 people were injured when an earthquake measuring 5.5 on the Richter scale hit northeastern Iran on Thursday, state television reported. The epicenter of the quake, which struck at 4:05 p.m., was 10 km (6 miles) outside the city of Neyshabur, some 70 km from the holy city of Mashhad, the official IRNA news agency said.
There had so far been 36 aftershocks since the main quake, IRNA said, adding that some buildings had been damaged and windows shattered in villages near Neyshabur.
“So far 100 people have been injured. Most of them were treated quickly and some have been hospitalized,” state television quoted a local official as saying, adding that rescue workers were in the area.
The news agency ILNA reported that the quake lasted seven seconds and was the strongest felt in the region for 10 years.
Many parts of Iran are prone to earthquakes. At least seven people were killed in a 6.5-magnitude quake that jolted the southeast in 2010, the same region where a huge tremor killed some 31,000 people in the city of Bam in 2003. source – Yahoo News
JAKARTA, Indonesia (AP) — A powerful earthquake has hit waters of western Indonesia, prompting local officials to issue a tsunami warning.
It was centered 18 miles (30 kilometers) beneath the ocean floor. Arief Akhir, an official with Indonesia’s geological agency, said a tsunami warning has been issued.
Indonesia is prone to seismic upheaval due to its location on the Pacific “Ring of Fire,” an arc of volcanos and fault lines encircling the Pacific Basin.
A giant quake off the country on Dec. 26, 2004, triggered a tsunami in the Indian Ocean that killed 230,000 people, half of them in Aceh. source – Yahoo News
