Argentine submarine explosion

Post by Michael_Seman » Fri Nov 24, 2017 7:15 pm

Reading in the news:

The sound was captured by the Comprehensive Nuclear-Test Ban Treaty Organization, a Vienna-based group, and shared with Argentine authorities.
The U.S. Navy and specialist agencies previously said a "hydro-acoustic anomaly" was detected just hours after the navy lost contact with the ARA San Juan on Nov. 15.

I once worked at a seismic station that was part of this nuclear test monitoring. The nearest CTBTO seismc station would be at Paso Flores which is on
the west side of Argentina, 300 km from the ocean.
I think it must have been a large explosion.

The SOSUS net picked up the loss of the USS Scorpion in '68 and the Norwegian NORSAR array detected the first explosion in the loss of the Kursk in 2000 (M1.5); I suspect that underwater and seismic monitoring stations are pretty much a "first go to" for this kind of thing.

They posted this image in a tweet(!) : which shows the detection range, but not the event size.

It must have been a large explosion indeed. I wonder if there's a chart somewhere for these things. I would imagine you could guess how strong it was judging by the readings, no?
