Quake rocks Washington area, felt on East Coast
By BOB LEWIS - Associated Press  AP Aug. 23, 2011 
MINERAL, Va. (AP) — One of the strongest earthquakes ever recorded on the East Coast shook buildings and rattled nerves from South Carolina to New England on Tuesday and forced the evacuations of parts of the Capitol, White House and Pentagon.

There were no immediate reports of deaths, but fire officials in Washington said there were at least some injuries. The U.S. Geological Survey said the quake registered at magnitude 5.8 and was centered about 40 miles northwest of Richmond, Va.
Two nuclear reactors at the North Anna Power Station, in the same county as the epicenter, were automatically taken off line by safety systems, said Roger Hannah, a spokesman for the U.S. Nuclear Regulatory Commission.


The earthquake came less than three weeks before the 10th anniversary of the Sept. 11 attacks, and in both Washington and New York it immediately triggered fears of something more sinister than a natural disaster.

At the Pentagon, a low rumbling built until the building itself was shaking, and people ran into the corridors of the complex. The shaking continued there, to shouts of "Evacuate! Evacuate!"

The Park Service closed all monuments and memorials on the National Mall, and ceiling tiles fell at Reagan National Airport outside Washington. All flights there were put on hold.

In lower Manhattan, the 26-story federal courthouse in lower Manhattan, blocks from ground zero of the Sept. 11 attacks, began swaying, and hundreds of people streamed out of the building.

Shaking was felt as far south as Charleston, S.C., and as far north and east as Martha's Vineyard, Mass., where President Barack Obama is taking summer vacation and was starting a round of golf when the quake struck at 1:51 p.m. EDT.

8reA magnitude of 5.8 would make the quake among the most powerful to strike the eastern United States. In 1897, a magnitude-5.9 quake was recorded at Giles County, Va., the largest on record in that state.

East Coast earthquakes are far less common than in the West, but they tend to be felt over a broad area.

"The waves are able to reverberate and travel pretty happily out for miles," said U.S. Geological Survey seismologist Susan Hough.

Amtrak said its trains along the Northeast Corridor between Baltimore and Washington were operating at reduced speeds and crews were inspecting stations and railroad infrastructure before returning to normal.

More than 12 million people live close enough to the quake's epicenter to have felt shaking, according to the Geological Survey. The agency said put the quake in its yellow alert category, meaning there was potential for local damage but relatively little economic damage.

The Virginia quake came a day after an earthquake in Colorado toppled groceries off shelves and caused minor damage to homes in the southern part of the state and in northern New Mexico. No injuries were reported as aftershocks continued Tuesday.

In Charleston, W.Va., hundreds of workers left the state Capitol building and employees at other downtown office buildings were asked to leave temporarily.

"The whole building shook," said Jennifer Bundy, a spokeswoman for the state Supreme Court. "You could feel two different shakes. Everybody just kind of came out on their own."

In Ohio, where office buildings swayed in Columbus and Cincinnati and the press box at the Cleveland Indians' Progressive Field shook. At least one building near the Statehouse was evacuated in downtown Columbus.

In downtown Baltimore, the quake sent office workers into the streets, where lamp posts swayed slightly as they called family and friends to check in.

Social media site Twitter lit up with reports of the earthquake from people using the site up and down the U.S. eastern seaboard.

"People pouring out of buildings and onto the sidewalks and Into Farragut Park in downtown DC...," tweeted Republican strategist Kevin Madden.

John Gurlach, air traffic controller at the Morgantown Municipal Airport was in a 40-foot-tall tower when the earth trembled.

"There were two of us looking at each other saying, 'What's that?'" he said, even as a commuter plane was landing. "It was noticeably shaking. It felt like a B-52 unloading."

Immediately, the phone rang from the nearest airport in Clarksburg, and a computer began spitting out green strips of paper — alerts from other airports in New York and Washington issuing ground stops "due to earthquake."

Federal officials: 2 nuclear reactors taken offline near quake site in Va.; No damage reported
By Associated Press, Updated: Tuesday, August 23, 5:09 PM
RICHMOND, Va. — Federal officials say two nuclear reactors at the North Anna Power Station in Louisa County, Va., were automatically taken off line by safety systems around the time of the earthquake.

The Dominion-operated power plant is being run off three emergency diesel generators, which are supplying power for critical safety equipment. The NRC and Dominion are sending people to inspect the plant.
A fourth diesel generator failed, but it wasn’t considered an emergency because the other generators are working, according to the Nuclear Regulatory Commission.

Dominion said it declared an alert at the North Anna facility and the reactors have been shut down safely and no major damage has been reported.

The earthquake was felt at the company’s other Virginia nuclear power station, Surry Power Station in southeast Virginia, but not as strongly there. Both units at that power station continue to operate safely, Dominion said.

The quake also caused Dominion’s newest non-nuclear power station, Bear Garden in Buckingham County, to shut down automatically.

NRC spokesman Roger Hannah says the agency was not immediately aware of any damage at nuclear power plants in the southeast.

Hannah said he knew of no other shut reactor but that unusual events were reported at a dozen other plant sites.

Louisa County is about 40 miles northwest of Richmond.

Bochibochiも揺れた時に地震かな?とは思ったのですが、こんな大事になってるとは・・・。
(すいません、地震のあと昼寝してました)

アメリカではこのM5.8でも記録的なことで、North Anna原発はとりあえず安全装置が作動して自動停止したようです。
今、もう一度別の記事がUPされたので、見てみたら4つあるディーゼル発電機の1機が動作しなかったようです。ちょ、大丈夫ですか??

昼寝から起きて、TVをつけたら市長(Mayor)が緊急会見してましたが、
「被害が少なくてラッキーだった」
と言っていました。10年目の9.11を前にみんなナーバスになっているようです。かなりの人が外に避難したようです。

とにかく、今の人類は、自然災害に立ち向かう術をもっていませんから、こちらでも、原発についてもうちょっと考えて欲しいなと思います。

今日は散歩やめておこうっと・・・。

ひとまず失礼します。

【追記】M5.9になっているようです。
米東海岸でM5.9の地震、原子炉2基が運転停止
ロイター 8月24日(水)6時35分配信
 [ワシントン 23日 ロイター] 米東海岸で23日午後、大きな地震が発生し、カナダでも揺れを感じた。多くの都市で建物が揺れ、電車や空の便に遅れが生じたほか、建物の中にいた数千人が避難した。
 これまでのところ、大きな被害や負傷などは報告されていない。

 米地質調査所によると、震源地はバージニア州ミネラルで、震源の深さは1キロ(0.6マイル)、地震の規模を示すマグニチュード(M)は5.9と推定されている。

 地震を受け、国防総省や連邦議会議事堂では職員らが一時避難した。

 米原子力規制委員会(NRC)によると、バージニア州ノース・アナ原子力発電所で、原子炉2基が運転を停止した。

 運転が止まったのはドミニオン・リソーシズ<D.N>の原子炉2基。外部電源が絶たれたものの、ディーゼル発電機は作動しているという

 ドミニオンのバージニア州・サリー原発の2基は運転を続けている

 ニューヨーク、ニュージャージー、ペンシルベニア、メリーランド各州の原発に影響はなく、地震により複数の原子炉で通常と異なる事象が確認されたが、大きな被害は報告されていないという。

米地震で停止原発の非常電源1機故障 NRC「警戒」を宣言
産経Biz 2011.8.24 13:03
 ロイター通信などによると、米東海岸の地震で23日、バージニア州の震源から約20キロの距離にあるノースアナ原発で停電が発生、原子炉2基が運転を自動停止した。非常用電源で電力供給し原子炉の冷却を行っているが、4機の発電機のうち1機が故障、同原発は、米原子力規制委員会(NRC)の原発非常事態を示す4段階レベルで下から2番目の「警戒」を宣言した

 同原発の運転を担当する会社によると、原発はマグニチュード(M)6・2の地震に耐えられる設計になっているという。同日の地震はM5・8で、専門家からは「設計基準に気掛かりなほど近い」と安全性を懸念する声が出ている。

 NRCは「原発は安全に停止し公共に被害が及ぶ危険はない」としている。しかし外部電源をいつ回復させられるのかは不明。(共同)

地球が怒ってるんですかね。

米ノースアナ原発:外部電源を回復
更新日時: 2011/08/24 12:47 JST
  8月24日(ブルームバーグ):米ドミニオン・リソーシズが運営するバージニア州のノースアナ原子力発電所は24日、外部電源が回復し、バックアップ用の発電機に依存する必要がなくなった。
