We've got a 1 in 6 chance of a mega-volcano erupting this century

Such a mega volcano eruption would be a real climate crisis unlike the phony climate change!

Why this major natural event was so underreported by media is more than strange!
"In mid-January 2022, most people didn’t notice anything special, but geologists knew we dodged a bullet. The Hunga Tonga-Hunga Ha’apai volcano erupted in Tonga, sending enough water into the atmosphere to briefly warm the planet. The eruption was one of the largest ever recorded; it essentially blew up an island, created tsunamis ...
We were lucky the eruption lasted only 11 hours — had it lasted longer, the damage would have spread to other areas in southeast Asia, one of the most densely populated areas in the world, which also hosts vital shipping lanes and key global agriculture and infrastructure."

"... Researchers classify volcanic eruptions in something called the Volcanic Explosivity Index (VEI). This index classifies eruptions in terms of total volume of ejecta, cloud height, and types of eruption (some can be more gentle, some can be more explosive). The VEI ranges from 1 to 8, with 1 being a “chill” Hawaiian eruption, and 8 being an absolute catastrophe and possibly, a civilization-ender.

VEI 8 eruptions are relatively rare (the Yellowstone eruption from 2.1 million years ago and the Toba eruption from 74,000 years ago are good examples) — but VEI 7 eruptions are not that rare. In fact, the odds of such an eruption within this century is around 1 in 6, which is way too close for comfort.
The last such eruption was the 1815 eruption of Mount Tambora. [followed by the year without summer] ..."

We've got a 1 in 6 chance of a mega-volcano erupting this century. Shouldn't we get prepared?

Huge volcanic eruptions: time to prepare More must be done to forecast and try to manage globally disruptive volcanic eruptions. The risks are greater than people think.
