SUMMARY

The LIGO observatories are not specifically designed to detect temblors with accuracy, as their primary function is to measure gravitational waves. While they possess advanced sensitivity, they are equipped to disregard seismic noise during earthquakes, making them less effective for this purpose compared to standard seismographs. Any reliable seismograph can detect earthquakes, and even inexpensive models can capture seismic activity globally. Thus, LIGO's technology is not necessary for earthquake detection.

PREREQUISITES
  • Understanding of gravitational wave detection technology
  • Knowledge of seismic measurement techniques
  • Familiarity with LIGO's operational principles
  • Basic concepts of earthquake magnitude and measurement
NEXT STEPS
  • Research the operational principles of LIGO and its sensitivity to gravitational waves
  • Learn about different types of seismographs and their capabilities
  • Investigate the technology behind inexpensive seismometers
  • Explore the relationship between seismic events and gravitational wave detection
USEFUL FOR

Seismologists, physicists, and anyone interested in the intersection of gravitational wave research and earthquake detection technology.

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.
