Weather Mizumoto is tweeting Mt. Aso experiencing a minor eruption.
Yeah, the video feed in the earlier post showed that from a helicopter.
Doesn’t look like much though. Although the big ones usually start off innocent looking enough.
Two M 5.8 quakes were recorded on the NE rim of the Mt. Aso caldera (not the present day volcano).
The caldera is one of the largest in the world, and contains some great hot springs, which I can attest are some of the best in Japan.
