How can volcanic eruptions be predicted?

Answer 1

Past data and trends and readings.

(Past data and trends) Eruptions can also be predicted by measuring the average time interval between eruptions, calculating the duration of the last eruption, and determining whether an eruption is expected or not. An increase in volcanic activity, for example, is frequently a good, but short-notice, warning of an impending volcanic eruption. (Readings)

Volcanic eruptions can be predicted through various methods including monitoring seismic activity, measuring changes in ground deformation, observing gas emissions, and tracking changes in temperature and composition of volcanic fluids. Additionally, historical data and geological studies of the volcano can provide valuable insights into its behavior and potential eruption patterns.
