問題詳情

Many people depend on volcanoes for their survival.The geothermal energy of a volcano can power technologicalsystems for nearby communities. Soil near active volcanoes isoften rich in mineral deposits and provides excellent farmingopportunities. Lots of people visit volcanoes each year, so jobsoften pop up nearby in hotels, restaurants, gift shops, and as tourguides. And some people simply do not have the financialresources to move.Many residents of the area around Kilauea may also thinkit’s worth the risk, given the beauty, community, and remotenessof Hawaii. Volcanoes also tend to give notice that something isabout to happen—Kilauea’s small earthquakes, increasingamounts of lava at the summit, and a change in the slope of thevolcano all indicated in recent weeks that an eruption mayhappen soon. This isn’t necessarily the case in other parts of theworld, where earthquakes, tornadoes, fires, and floods can springup without warning.The evacuation of nearby communities because ofKilauea’s eruption isn’t the only instance in recent months ofpeople leaving their homes to get out of the path of an eruptingvolcano. When Mount Mayon in the Philippines began spewingash into the air in January, tens of thousands of people needed toevacuate. Over 100,000 people in northeast Bali were evacuatedin November when Indonesia’s Mount Agung began rumbling,and thousands of tourists also fled.

【評論內容】許多人依靠火山來生存。火山的地熱能為附近社區的技術系統提供動力。活火山附近的土壤通常富含礦藏，並提供良好的耕作機會。每年都有很多人參觀火山，所以工作經常會出現在酒店，餐館，禮品店和導遊附近。有些人根本沒有財力來搬家。基於夏威夷的美麗，社區和偏遠地區，基拉韋厄周邊地區的許多居民也認為值得冒這個風險。火山也傾向於注意到即將發生的事情 - 基拉韋厄的小地震，峰頂熔岩量的增加以及火山坡度的變化都表明最近幾周火山噴發很快就會發生。世界其他地區的情況並不一定如此，地震，龍捲風，火災和洪水都會在沒有警告的情況下爆發。由於基拉韋厄火山爆發，附近社區的疏散並不是最近幾個月人們離開家園走出火山噴發道路的唯一例子。菲律賓的馬榮山於1月份開始向空中噴出灰燼，成千上萬的人需要撤離。 11月，當印度尼西亞的阿貢山開始隆隆聲時，巴厘島東北部的10萬多人被疏散，成千上萬的遊客也紛紛逃離。
