If you, like me, have Google alerts for the terms “volcano,” “earthquake,” “end of days,” and “survivalist cult now accepting applications,” the recent news that both Mount St. Helens and Yellowstone’s supervolcano are showing signs of activity may have had you reaching for your bug-out bag. Then again, if you’re more afraid of climate change than natural disasters, massive volcanic explosions might actually sound like a good thing, right? After all, a huge plume of ash could block sunlight and lower global temperatures.

Here’s what’s up in volcano news: Over the past two months, Mount St. Helens in Washington state, located a scant 174 miles from this author’s house, has been experiencing an “earthquake swarm.” More than 130 small quakes have rumbled beneath the mountain, indicating that magma is on the move. But while this sounds terrifying, it’s actually nothing to worry about, according to the U.S. Geological Survey, which wrote on Facebook that “there are no signs of an imminent eruption.” Whew.

But what about Yellowstone? Yellowstone National Park is located on top of a supervolcano, and scientists discovered a few years ago that the massive magma reservoir beneath it is two and a half times larger than previously believed, measuring 55 miles across. An eruption there could be 2,000 times larger than the blast at St. Helens in 1980 that killed 57 people, and, Tech Insider reports, such an event could cover much of the Midwest in ash, wipe out food and water supplies, and render vast swaths of land uninhabitable for at least a decade.
