Earthquakes and increased geyser activity have sparked anxiety of an imminent Yellowstone eruption.

地震和间歇泉活动的增加,引发了人们对黄石公园火山爆发的担忧。

The Yellowstone Caldera is home to a dormant supervolcano, which could cause mass destruction if it erupted again.

黄石火山是一座休眠的超级火山,如果它再次爆发,可能会造成大规模的破坏。

And two recent strong earthquakes in southern California have sent fears skyrocketing that they could cause the supervolcano to reawaken in wrath and fire.

最近在南加州发生的两场强烈地震,引发了人们对超级火山可能在愤怒和大火中再次苏醒的担忧。

The United States Geological Survey (USGS) reports 73 earthquakes in the Yellowstone National Park region during June, including two earthquake swarms.

美国地质调查局(USGS)报告说,6月份黄石国家公园地区发生了73次地震,其中包括两次地震群。

There's also been increased geyser activity inside Yellowstone Park. So far this year the Steamboat Geyser has erupted 25 times, according to the USGS, putting it on track to break the yearly record of 32 eruptions.

黄石公园内的间歇泉活动也在增加。据美国地质调查局称,今年到目前为止,蒸汽船间歇泉已经喷发了25次,有望打破每年32次喷发的记录。

The USGS says the Steamboat Geyser erupted seven times in June alone and broke the record for the shortest interval between eruptions.

美国地质勘探局说,仅在6月份,蒸汽船间歇泉就喷发了7次,打破了喷发间隔最短的记录。

However, the USGS says the Californian earthquakes won't trigger a volcanic eruption at Yellowstone, although they still can have an impact on volcanoes.

然而,美国地质调查局表示,加州地震尽管会对火山产生影响,但不会引发黄石公园的火山爆发。

"Earthquakes like those of the past week are unlikely to trigger volcanic eruptions, although they might trigger microearthquakes at some volcanoes," it notes.

报告指出:“像上周那样的地震可能会在一些火山引发微地震,但不太可能引发火山爆发。”

"The last lava eruption was 70,000 years ago, and the last huge explosion was 631,000 years ago. To get magma to the surface, you need pressure and a volume of eruptible magma. The magma reservoir at Yellowstone is mostly solid. And there's no indication of pressurization."

“最后一次熔岩喷发是在7万年前,最后一次大爆炸是在63.1万年前。要把岩浆带到地表,就需要压力和大量可喷发的岩浆。但目前黄石公园的岩浆储藏库大部分是固态的,也没有压力的迹象。”

And Michael Poland, the USGS scientist-in-charge of the Yellowstone Volcano Observatory, told CNN the increased geyser activity is nothing to worry about.

负责黄石火山观测站的美国地质调查局科学家迈克尔·波兰表示,间歇泉活动的增加没什么好担心的。

"They're mostly random and experience phases of alternating eruptive activity," he said.

“经历了交替喷发活动的阶段,它们大多是随机的”他说。

"So while fascinating, it's not unusual, nor cause for concern."

“所以,虽然很有趣,但这并不罕见,也不值得担忧。”
