Volcanologists use a variety of techniques to monitor volcanic activity. This includes using seismometers to measure earthquakes, GPS to measure ground deformation, and tiltmeters to measure changes in the tilt of the ground. Volcanologists also use satellite imagery and aerial photography to monitor changes in the shape of the volcano. In some cases, volcanologists will also use infrasound to detect volcanic eruptions.
Seismometers are the most common type of instrument used to monitor volcanoes. They are used to measure earthquakes, which can be used to infer the level of activity at a volcano. GPS is also commonly used to measure ground deformation, which can be used to track the movement of magma beneath a volcano. Tiltmeters are used to measure changes in the tilt of the ground, which can be used to detect changes in the shape of a volcano. Satellite imagery and aerial photography are also used to monitor changes in the shape of a volcano.
In some cases, volcanologists will also use infrasound to detect volcanic eruptions. Infrasound is a type of sound that is lower in frequency than what humans can hear. It can be used to detect the sound of an eruption before it is visible to the naked eye. Infrasound can also be used to track the movement of ash clouds from an eruption.
