美国有线新闻 CNN 冰岛一周地震17000余次 火山随时可能爆发(在线收听) |
The European nation of Iceland is called that because it's home to both volcanoes and glaciers. A nd meteorologists say there are signs that a volcanic eruption is brewing. Southwestern Iceland has seen 17,000 earthquakes over the past week according to the Icelandic Meteorological Office. Sound like a lot? It is a lot. One resident told CNN that it's very unusual to feel the Earth shake 24 hours a day for a whole week. The largest of these tremors had a magnitude of 5.6. That's considered a moderate quake de?pending on how deep it is. There have been some small cracks in the roads and rock falls where the ground is steeper but aside from that not a lot of damage has been reported. The tremor seemed to calm down from Wednesday to Thursday but a government official doesn't think the seismic activity is over. And while scientists don't know exactly what's caused this swarm of quakes, a University of Iceland volcanology professor thinks they might be because there's been a quote "intrusion of magma into the Earth's crust in southwest Iceland." This is where several volcanoes are located and it's especially concerning because 2/3 of the country's population lives in the southwestern part of the island. University computer models predict that if there's an eruption, the resulting lava flows probably won't impact any nearby towns or the region's international airport but again, that's only based on models. All this has triggered a range of reactions from people there from anxiety to excitement and cameras have been put on standby to live stream an eruption should one take place. 欧洲国家冰岛之所以被称为冰岛,是因为其是火山和冰川的故乡。气象学家表示,有迹象表明火山喷发可能在酝酿中。 冰岛气象局表示,过去一周,冰岛西南部发生了1.7万次地震。听起来像很多?确实很多。一名居民在接受CNN采访时表示,整个星期每天24小时都能感受到地面震动,这种经历相当不同寻常。其中最大震级达到5.6级。根据深度,这被认定为中等地震。 道路上出现小裂缝,地面较陡的地方也出现了落石,但除此之外,没有太多损毁报告。从周三到周四,地震似乎渐渐停止,但一名政府官员认为地震活动还没有结束。虽然科学家尚不清楚导致这一系列地震的原因,但冰岛大学的一名火山学教授认为,这可能是因为“冰岛西南部的岩浆侵入地壳”。 该地区有多座火山,尤其令人担忧的是,该国三分之二的人口生活在岛国冰岛的西南部地区。大学计算机模型预测,如果火山爆发,产生的熔岩流可能不会影响附近的任何城镇或该地区的国际机场,但这只是基于模型预测得出的结论。这一切都引发了该地区人们的一系列反应,有人焦虑或兴奋,还有人已备好摄像机,随时准备直播火山爆发。 |
