No earthquake in modern times has been this powerful, ... “The analogy is like an instrument — a little, small kazoo, you can’t make it very loud,” Scharer said.

The strongest earthquake ever recorded, a 9.5-magnitude one that occurred in Chile in 1960, was 30,000 times more powerful than a 6.5-magnitude quake, which itself can be very destructive.

After the 2022 earthquake, one instrument close to Steamboat registered a change in the intensity of this hydrothermal noise, says Reed.
