Can the LIGO observatories detect (with accuracy) temblors?

In summary, the conversation discusses the sensitivity of earthquake detecting instruments, specifically LIGO and seismometers. It is mentioned that even a small earthquake in California can trigger a reaction in these instruments, and that LIGO is designed to minimize the impact of seismic events. It is also mentioned that even inexpensive seismometers can detect earthquakes from around the world.

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.

1. Can the LIGO observatories detect all types of temblors?

Yes, the LIGO observatories are designed to detect all types of temblors, including earthquakes, volcanic activity, and even man-made explosions.

2. How accurate is the LIGO observatory in detecting temblors?

The LIGO observatory has a high level of accuracy in detecting temblors. It can detect changes in the Earth's surface of less than a billionth of a meter.

3. Can the LIGO observatories detect temblors in real-time?

Yes, the LIGO observatories have the capability to detect temblors in real-time. This means that they can provide immediate and accurate information about seismic activity as it occurs.

4. How far away can the LIGO observatories detect temblors?

The LIGO observatories can detect temblors from thousands of kilometers away. They have the ability to detect seismic activity from all over the world, making them a valuable tool for monitoring global seismic activity.

5. Can the LIGO observatories predict when a temblor will occur?

No, the LIGO observatories are not able to predict when a temblor will occur. They can only detect and measure seismic activity after it has already happened.
