I Can the LIGO observatories detect (with accuracy) temblors?

With all the earthquakes going on in CA - and that the last one (7.1 mag) was strong enough to possibly trigger a small quake along the LA coast (i.e., as in LouisianA, not Los Angeles) - I was wondering about this. These instruments are so sensitive that they have to pick something up, even in LA & WA. I presume that they can discern when a temblor happens and zero out the effect.

Yes. But you don't need LIGO for that. Any decent seismograph will see those earthquakes.

They have seismometers and discard measurements during earthquakes. LIGO is designed to be as decoupled from seismic events as possible. Meanwhile even quite cheap seismometers can pick up these earthquakes from all over the world.
