Because laser beams are pulses of pure light - travelling at a known speed. The equipment times how long the pulses take to bounce back from the volcano - if the time differs from scientists calculations, the volcano has either expanded or shrunk - possibly indicating an imminent eruption.

What are measuring devices with lasers used for with earthquakes?
Laser-ranging devices us laser beams to detect the fault movements that cause earthquakes.
When will there be laser beams in battle?
Laser beams are already used in some military applications, primarily for target designation, range finding, and missile guidance. However, the use of laser weapons in battle is still limited due to technical challenges such as power requirements, beam divergence, and atmospheric interference. Research and development into laser weapon systems are ongoing, but widespread deployment in combat situations is not yet common.
What are laser optics used for?
Semiconductor lasers are used for different applications to solve various problems, such as, measuring in a direct way, the blood perfusion of body tissue. It is an instrument that can be used in the defense industry, internet applications and many other uses.
What uses a laser beams detect horizontal fault movements?
Laser beams are used in a technique called laser interferometry to detect horizontal fault movements. This method involves directing a laser beam along a baseline between two points and measuring any changes in the interference pattern caused by shifts in the ground. As tectonic activity causes horizontal displacement, even minute movements can be detected by analyzing these patterns. This technology provides precise measurements crucial for understanding and monitoring seismic activity along fault lines.
What instruments are used on volcanoes?
Instruments used on volcanoes include seismometers to monitor earthquakes, gas sensors to detect changes in gas emissions, GPS to track ground deformation, thermal cameras to monitor temperature changes, and satellite imagery to capture overall volcanic activity. These instruments help scientists better understand and monitor volcanic behavior for early warning signs of potential eruptions.
What gem is commonly used in creating laser beams?
