Seizmic Activity & Quantum Gravity: LIGO Info & Plans

[exponent137]

1. Does LIGO give also any information about seizmic activity? (I think as aspect intended primary to seizmic activity, not in connection with gravitational waves.)

2. Will measurement of gravitational wave give any information about quantum gravity? Is here any plan for this usage?

1 - no. The instrument is very carefully isolated so that it doesn't react to things like seismic activity. It wouldn't surprise me if they have highly accurate monitoring systems that would tell you about seismic activity, but the experiment itself is blind to it.

2 - no. Gravitational waves are a purely classical phenomenon. Although the event was very high energy we are only seeing the ripples of it which are definitely far away from where we think quantum gravitational effects might be detectable.
