Yes, laser ranging devices are highly sensitive instruments that can detect small movements in the Earth's crust. By measuring changes in distance with high precision, these devices can detect even subtle ground deformations caused by tectonic activities or other geological processes. This capability makes laser ranging valuable for monitoring and studying seismic events and crustal movements.
Laser-ranging devices are highly sensitive and precise instruments that can detect even subtle movements of the crust along fault lines or tectonic plate boundaries. They work by measuring the distance between the instrument and a target point with high accuracy, allowing scientists to monitor changes in the Earth's crust and potentially predict earthquakes or volcanic activity. This technology plays a crucial role in understanding and monitoring geologic hazards.
They use an interferometer. It can determine distance down to 1/2 wavelenght of light which is pretty small. The sent and returned light is compared. You said where, the answer is how.

Earthquakes often occur along faults or breaks in Earth's crust where movements occur. These movements happen when stress builds up along the fault and is released suddenly, causing the rocks to break and generate seismic waves. Earthquakes can range in intensity depending on the magnitude of the movement along the fault.
Movements of the Earth's crust usually take place along plate boundaries, where tectonic plates interact. These interactions can result in events such as earthquakes, volcanic eruptions, and the formation of mountain ranges.
Tectonic plate movement is detected using instruments called GPS receivers and seismometers, along with satellites. GPS receivers can measure the movement of the Earth's crust, while seismometers detect seismic waves generated by plate movements. Satellites also provide valuable data on crustal deformation and plate motions.
it comes from the crust
When plates within the Earth's crust bend and crack, faults are formed. Faults are fractures in the Earth's crust where movement has occurred along the break. These movements can be either vertical or horizontal, causing earthquakes.
