NASA researchers have an estimate of the power of a massive volcanic eruption that took place on Saturday near the island nation of Tonga.
"We come up with a number that's around 10 megatons of TNT equivalent," James Garvin, the chief scientist at NASA's Goddard Space Flight Center, told NPR.
That means the explosive force was more than 500 times as powerful as the nuclear bomb dropped on Hiroshima, Japan, at the end of World War II.
