Seismometers such as this one installed near Mount Spurr volcano (on skyline in background) provide the Alaska Volcano Observatory with a continuous, telemetered record of volcanic earthquakes. Scientists use this data to monitor earthquake types, locations, and magnitudes to decipher different processes under and within a volcano.
