在8.2级强烈地震引发太平洋海啸警报后，沿海居民被敦促逃离家园，前往地势较高的地方。

在美国西北部的阿拉斯加州科迪亚克市发生了今年最强烈的地震和50多年来美国最大的地震后，海啸警报在该市响起。

詹妮弗.索恩（Jennifer Sonne）分享了一段视频剪辑，在她搬到科迪亚克高地时捕捉到了警报声，她在推特上写道：“Omfg 7+地震就在附近。科迪亚克海啸警报。

“我现在在这里。盯着大海（脸上恐惧的尖叫表情），然后撤离。”


8.2级地震后发布了海啸警报

夏威夷离阿拉斯加约2500英里，海啸监测已经发布，而在离阿拉斯加近7000英里的新西兰官员正在评估潜在的威胁。

这场海底地震最初估计为8.1级，但后来修正为8.2级，袭击了阿拉斯加佩里维尔东南约55英里处，深度约30英里。

随后发生了强烈的海底余震，强度分别为6.2级和5.6级，发生在距奇尼克市约85英里的地方。

美国国家海啸预警中心敦促生活在预警区内的人们立即离开家园前往地势较高的地方。

它说：“根据您的情况，疏散到内陆或指定海啸危险区以上或以外的高地，或转移到多层建筑的上层。

“有可能发生具有破坏性波浪和强大洋流的海啸。

“当海浪到达岸上，向内陆移动，并流回海洋时，可能会发生反复的沿海洪水。

“强烈和不寻常的波浪、洋流和内陆洪水会淹死或伤害人，削弱或破坏陆地和水中的结构。

“充满漂浮或淹没的碎片的水可能会伤害或杀死人，削弱或摧毁建筑物和桥梁。

港口、码头、海湾和入海口中强烈而不寻常的洋流和波浪可能特别具有破坏性。”

Coastal residents are being urged to flee their homes for higher ground after a powerful 8.2 magnitude earthquake triggered a tsunami warning for the Pacific Ocean.

Tsunami sirens were going off in the city of Kodiak, Alaska, after the north-western US state was rocked by the strongest tremor this year and the largest in America for more than 50 years.

Jennifer Sonne, who shared a video clip which captured the sound of a siren as she moved to higher ground in Kodiak, tweeted: "Omfg 7+ earthquake near here. Tsunami warning for Kodiak.

"I am currently here. Staring at the ocean like [face screaming in fear emoji] and evacuating."


A tsunami warning was issued following the 8.2 magnitude earthquake

A tsunami watch was issued for Hawaii, which is about 2,500 miles from Alaska, while officials almost 7,000 miles away in New Zealand were assessing the potential threat.

The undersea earthquake, initially estimated to be 8.1 but then revised to 8.2, struck about 55 miles south-east of Perryville, Alaska, at a depth of about 30 miles.

It was followed by powerful undersea aftershocks as strong as 6.2 and 5.6, occurring about 85 miles from the city of Chignik.

The US National Tsunami Warning Center urged people living within the warning area to immediately leave their homes for higher ground.

It said: "Evacuate inland or to higher ground above and beyond designated tsunami hazard zones or move to an upper floor of a multi-story building depending on your situation.

"A tsunami with damaging waves and powerful currents is possible.

"Repeated coastal flooding is possible as waves arrive onshore, move inland, and drain back into the ocean.

"Strong and unusual waves, currents and inland flooding can drown or injure people and weaken or destroy structures on land and in water.

"Water filled with floating or submerged debris that can injure or kill people and weaken or destroy buildings and bridges is possible.

"Strong and unusual currents and waves in harbors, marinas, bays, and inlets may be especially destructive."
