美国旧金山发生25年来最强地震

2014-08-25    来源:BBC    【      美国外教 在线口语培训

当地时间凌晨3点20左右,美国加州旧金山北部地区(北纬38.21° 西经122.32°),发生6.0级地震,震源深度11千米。这是旧金山湾区自25年前发生6.9级地震以来遭遇的最强震。

震中位于旧金山东北约60余公里的纳帕酒乡美国峡谷(American Canyon),之后又有60余次小级别余震,目前已造成120人受伤,纳帕地区大面积停电。

目前没有死亡报告,但是至少120人在本次地震中受伤。其中一名儿童被壁炉压伤,状况危急。

An earthquake with a magnitude of 6.0 has shaken northern California, causing injuries and damage to buildings.

The USGS said it struck at 03:20 local time (10:20 GMT) four miles (6km) north-west of the town of American Canyon, at a depth of 6.7 miles.

At least 87 people have been taken to hospital in the Napa area, with three of them seriously injured.

California Governor Jerry Brown has declared a state of emergency in order to deal with the effects of the quake.

Officials in Napa said in a statement that the quake had destroyed four mobile homes and made 16 buildings "uninhabitable", as well as causing "approximately 50" gas main breaks and around 30 leaks from water mains.

Three historic buildings in the town had been hit and two commercial buildings "severely damaged", the statement went on.

More than 10,000 households were without power in Napa, about six miles from the earthquake's epicentre, and the surrounding area, the Pacific Gas and Electric Company said.

A Red Cross evacuation centre has been set up in a church in the city.

The California Highway Patrol in the San Francisco Bay area tweeted that it was "checking over crossings and bridges for obvious signs of structural integrity", and asked residents to report any signs of problems.

The site of the earthquake was 51 miles from Sacramento and about 30 miles north-east of San Francisco, where many Twitter users say the earthquake woke them up.

Sarah McLellan tweeted: "On 6th floor entire building swaying, shaking", while Matt Dyar said: "Major shaker. Stuff off shelves. Broken glass. No house damage that is obvious."

Another Twitter user said: "I haven't felt one that big since the Northridge quake in the early 90s."

Numerous small aftershocks were also reported on Sunday.

California lies on the San Andreas Fault, which forms the tectonic boundary between the Pacific Plate and the North American Plate, two of the large moving plates that form the Earth's crust.

The San Francisco earthquake of 1906 and subsequent fires devastated the city.

In 1989, a powerful earthquake struck San Francisco, killing more than 60 people and injuring hundreds.
