Supposedly, the explosion of Krakatoa was the loudest sound humans have ever heard.

Krakatoa ejected about 11 Cubic miles of material.

Tambora in 1815 ejected about 20 Cubic miles of material.

Toba 74,000 years ago ejected about 3,000 Cubic miles of material.

Loud is a subjective term.

Where was Toba?

[Mr.Atos]

I think the point was that it was the loudest sound ever 'reported' having been heard, and that when people in San Fransisco heard it, that was an frighteningly impressive event.

When Toba blew, humans were little more than naked savages living in caves.

Where does Thera fall in those statistics (Santorini 1628 BC)?
