Ominous Earthquake Swarm At Yellowstone Supervolcano Now One Of Longest Ever Recorded

Yellowstone 超級火山地震群持續(xù)活躍 持續(xù)活躍狀況延續(xù)時間超長

The rumblings beneath the formerly dormant supervolcano known as the Yellowstone caldera just won't quit. And the ongoing earthquake swarm at the Yellowstone National Park supervolcano is now one of the longest ever recorded, having started on June 12.

Yellowstone 超級火山地底傳來轟鳴聲。6月12日后地震群持續(xù)活躍，持續(xù)活躍狀況延續(xù)時間超長。

Over the past three and a half months,almost 2,500 earthquakes have been recorded in the western part of the national park. This is on par with the biggest swarm ever recorded, where more than 3,000 earthquakes took place over three months,?Newsweek?reports.

過去的3個半月里國家公園西側(cè)記錄到接近2500次的地震。地震數(shù)量接近歷史最高記錄，3個月的最高歷史記錄為超過3000次地震。

In its latest monthly update about activity at Yellowstone, the US Geological Survey said 115 earthquakes had been reported in the park during September.Of these, 78 were part of the ongoing swarm 6 miles north of West Yellowstone.The biggest event in the swarm last month was magnitude 2.3.

9月份美國地質(zhì)調(diào)查局記錄到115次地震。地震群地震震級最高為2.3級。

While scientists at the USGS have brushed off the threat of a supervolcano eruption, scientists at NASA have said it represents a potentially devastating threat to the US population. These same scientists have suggested several risky strategies to prevent an eruption if one appears imminent.

美國地質(zhì)調(diào)查局的科學家們不認為存在超級火山噴發(fā)的威脅，美國宇航局的科學家們聲稱超級火山問題可能是嚴重的威脅。美國宇航局的科學家們已經(jīng)提出數(shù)種高風險應對處理方案。

Brian Wilcox, a former member of the NASA Advisory Council on Planetary Defense, and several other NASA researchers over the summer shared a report previously unseen outside the space agency about the threat Yellowstone poses, and what can be done to prevent an eruption.

美國宇航局的科學家們已經(jīng)對外公布了1份原先的內(nèi)部報告，這份報告講述了 Yellowstone 超級火山帶有的威脅，以及如何防止火山噴發(fā)。

According to NASA,an eruption at Yellowstone could plunge the earth into a volcanic winter and destroy crops and livestock, precipitating widespread famines.? Food reserves would only last about 74 days, according to the UN, after an eruption of a super volcano, like that under Yellowstone.

美國宇航局內(nèi)部有這樣的看法，Yellowstone 超級火山可能將地球拖入1個火山冬季：毀滅農(nóng)作物和牲畜，導致饑荒蔓延。依據(jù)聯(lián)合國的報告，超級火山噴發(fā)后食物儲備只能提供74天的糧食供應。

With an eruption long overdue, NASA has devised a plan to drill into the caldera and try to artificially cool it – a strategy that researchers say comes with its own risks.

火山噴發(fā)一直未發(fā)生，宇航局設計了1個方案：沿火山口方向挖掘進入火山內(nèi)部，人為處理火山問題。

Scientists at the USGS say the monthslong earthquake storm at the caldera has ended; however, they played down the risks posed by the swarm shortly after it started over the summer, only for the rumbling to continue. Others maintain that an eruption is long overdue.

美國地質(zhì)調(diào)查局的科學家們聲稱持續(xù)數(shù)月的地震風暴已經(jīng)結(jié)束。美國地質(zhì)調(diào)查局的科學家們6月份以后評估地震群危險程度不高。
