(여행) 아이슬랜드 얼음과 화산의 나라
We’re back tonight with a closer look at a nation we’ve all been watching closely lately because it’s quite literally a hotbed 온상 of volcanic activity. Tonight while flights around the world are still getting back to normal, in Iceland, they worried that a wind shift might shut down their major airports. It’s an active environment there because Iceland sits on top of what may be the largest crack in the crust지각 to the earth anywhere on earth. Our chief science correspondent Robert Bazel is there and got this close-up look.
This current eruption is one more demonstration of the earth’s awesome무시무시한 fire power in this land of volcanos. Iceland, the size of Kentucky, has 35 active volcanoes with an eruption on average every two or three years. It is a place where much of the surface is very close to the immense거대한 heat from the center of the planet. These steam baths were throughout the country occurred because water sips조금씩 스며들다 into the earth and heats the molten녹은 rock which is right beneath the surface.
Iceland’s earth structure comes from the same forces that produce earthquakes, tsunamis and volcanoes. The huge sections of the earth called plates that are in constant motion. This island nation straddles두발을 벌리다 a plate boundary called the Mid Atlantic ridge. This is actually a fault line단층선. On this side is the North American plate. On that side is the European plate. They’re moving apart at the rate of about one inch a year. That ever expanding fissure갈라진 틈 allows the molten rock from within the earth to rise constantly.
For seismologist지진학자 like Bryndis Brandsdottir, the challenge is enormous. “There’s lots of activity, you know, you don’t have to wait to run for the data. You usually, you know, you have too much work, too much data to.” The volcanoes have produced some spectacular distance.
And geothermal heat offers great opportunities for recreation as well as warmth and electricity for 80% of the nation’s houses. But it also poses a danger that we now know can affect much of the world. Robert Bazel, NBC News, Iceland.
