"Saw at Twitter thread with a 10 MT estimate."

Volcanic eruptions are measured not by megatons, but how it compares on the VEI scale ; Volcanic Eruption Index: a logarithmic scale - each 10 times larger then the preceding number.

In this case comparable to Mt St Helens at a VEI of 4 to 5.

Mount Pinatubo had a VEI of 6. Tambora had a VEI of 7

The only number I could find for material ejected was 400,000 tonnes of sulfur dioxide. A minuscule (0.0002717429 cubic miles) amount compared to the other eruptions above.

Krakatoa ejected 20 million tons of sulfur dioxide, with the ash cloud reaching 50 miles

A graphic for comparison :

I understand the conventional measurement criteria for volcanic eruptions. There is a video circulating of an object that dropped in the water just seconds before the eruption. There is speculation that it was a nuke weapon dropped on top of the volcano. The 10MT estimate is for the weapon, not the follow on volcanic eruption. The Russians have a nuke torpedo rated at 250MT that stands as a threat to generate tsunamis on east and west coasts of North America.

I haven't tracked down the waveform signatures. One of my co-workers specializes in identifying the difference between normal seismic waveforms and nukes. That information would sort whether the speculation was valid.

Might be a little late for this thread but been busy.

Go on Youtube, or whatever and do a search on Silver Creek Caldera. Or Peach Springs Tuff.

Simply amazing. They figure it was a one day event.
