Volcanic eruption is a rupture that occurs in the earth’s crust in which volcanic ash, hot lava and gases are discharged through a vent under the surface. The same methods used to predict earthquakes can be used by scientists to predict volcanic eruptions. Various monitoring methods such as the use of seismographs, tiltmeters and correlation spectrometers (COSPECS) can be used. Seismographs can help to discover small earthquakes, tiltmeters can estimate the subtle swelling of a volcano, while COSPECS can track and measure quantities of sulfur dioxide which is a gas that is discharged before an eruption.
