While I was trying to make an off colored joke .... you got the real meaning of my post. It will be interesting to see if this awakens Toba .... if they don't have an accurate map of the lake's bottom they better get one ASAP!
Quite possible.
If I recall correctly there was a MAJOR subsea earthquake close to Antartica just a few days before this one.
Reason it didnt attract much attention was the fact the area was mostly unpopulated.
From what I understand this latest one really "rattled the earth"
There could very easily be more, and soon.
