7.6 Magnitude Earthquake Shook Costa Rica and a Wide Area of Central America


Powerful Earthquake Reported in Costa Rica





A powerful, magnitude-7.6 earthquake shook Costa Rica and a wide swath of Central America on Wednesday. There were no immediate accounts of injuries, but communications were down near the epicenter.
The USGS said the 8:42 a.m. quake struck about 38 miles (60 kilometers) from the town of Liberia. It was centered about 25 miles (41 kilometers) below the surface. The magnitude initially was estimated at 7.9.
In the town of Hojancha near the epicenter, city official Kenia Campos said the quake knocked down some houses and landslides blocked two roads.
"So far, we don't have victims," she said. "People were really scared ... We have had moderate quakes but an earthquake (this strong) hadn't happened in more than 50 years."
There were no initial reports of damage or deaths in the capital of San Jose, said Douglas Salgado, a geographer with Costa Rica's National Commission of Risk Prevention and Emergency Attention.
Salgado said, however, officials were having problem accessing the earthquake zone or reaching people there and were flying over the area to assess damage to highways and other structures.
The earthquake didn't knock out phones or electricity in the capital 88 miles (141 kilometers) from the epicenter, Salgado said by telephone, but communications were down near the epicenter.
"There's chaos in San Jose because it was a strong earthquake of long duration," Salgado said. "It was pretty strong and caused collective chaos."
At the Hotel Punta Islita in the Guanacaste area, "everybody is crying a lot and the telephone lines are saturated," said worker Diana Salas, speaking by telephone, but she said was no damage there
In the coastal town of Nosara in northwest Costa Rica, trees shook violently and light posts swayed. Teachers chased primary school students outside.
A tsunami warning was in effect for Costa Rica, Panama and Nicaragua, the Pacific Tsunami Warning Center said in a bulletin. It said it was unknown if a tsunami was generated, but the warning was based on the size of the earthquake.

Powerful earthquake reported in Costa Rica

Updated 9:08 a.m., Wednesday, September 5, 2012


NOSARA, Costa Rica (AP) — A powerful, magnitude-7.6 earthquake shook Costa Rica and a wide swath of Central America on Wednesday, collapsing some houses, blocking highways and causing panic, but there were no immediate reports of deaths.

The USGS said the 8:42 a.m. quake struck about 38 miles (60 kilometers) from the town of Liberia. It was centered about 25 miles (41 kilometers) below the surface. The magnitude initially was estimated at 7.9.

In the town of Hojancha near the epicenter, city official Kenia Campos said the quake knocked down some houses and landslides blocked two roads.

"So far, we don't have victims," she said. "People were really scared ... We have had moderate quakes but an earthquake (this strong) hadn't happened in more than 50 years."

There were no initial reports of damage or deaths in the capital of San Jose, said Douglas Salgado, a geographer with Costa Rica's National Commission of Risk Prevention and Emergency Attention.

Salgado said, however, officials were having problem accessing the earthquake zone or reaching people there and were flying over the area to assess damage to highways and other structures.
The earthquake didn't knock out phones or electricity in the capital 88 miles (141 kilometers) from the epicenter, Salgado said by telephone, but communications were down near the epicenter.
"There's chaos in San Jose because it was a strong earthquake of long duration," Salgado said. "It was pretty strong and caused collective chaos."

At the Hotel Punta Islita in the Guanacaste area, "everybody is crying a lot and the telephone lines are saturated," said worker Diana Salas, speaking by telephone, but she said was no damage there

In the coastal town of Nosara, roughly 50 miles (80 kilometers) north of the epicenter, trees shook violently and light posts swayed. Teachers chased primary school students outside at the quake hit. Roads cracked and power lines fell to the ground.

A tsunami warning was in effect for Costa Rica, Panama and Nicaragua, the Pacific Tsunami Warning Center said in a bulletin. It said it was unknown if a tsunami was generated, but the warning was based on the size of the earthquake.

Radioactive Plume From Japan's Recent Earthquake Activity.




Strong 6.8 earthquake hits Fukushima Japan, tsunami warning up

 +
A strong 6.8 earthquake struck Friday at the northeastern coast of Japan near the Fukushima Nuclear Power Plant which was severely damaged by the March 11 super earthquake and tsunami that caused the death of close to 20,000 people near Fukushima
tsunami warning was issued in the Fukushima and Miyagi Perfectures but was lifted 35 minutes later.
The quake reportedly occurred at 2:36 pm (0536GMT) with its epicenter off Fukushima prefecture at a depth of 20 kilometers.
Tokyo Electric Power Company (TEPCO), the company that operates the badly-damaged Fukushima Nuclear Power Plant, said there were no damages on its Onagawa Plant which has been shut since March.
However, a report say "ground under Fukushima plant is cracking and radioactive steam is coming up — Melted core may be moving out of building" enenews.com reports.
In a video interview, Dr. Robert Jacobs, Hiroshima Peace Institute: “It’s a very serious and alarming development because this started to happen specifically after two large earthquakes in the last few weeks, there was a 6.4 on the 31 of July 31 and a 6.0 on August 12″.
Meanwhile, the NY Times reports that radioactive contamination in rice, a national grain, has been found by Japanese inspectors Friday.
The discovery is likely to fan out growing fears of radioactive contamination on crops and basic agricultural produce and the general safety of Japan's food supply.
