What are the different ways of predicting a volcano?

Answer 1

Volcano eruptions are difficult and sometimes dangerous to predict, but recent discoveries have made forecasting somewhat easier. There are many different methods, including using tiltmeters, taking seismic readings, measuring poison gasses, and using satellites. Bernard Chouet, a volcanologist, believes to have discovered the language of volcanoes and how to tell when they will erupt by using signals in seismic readings. Many of his predictions have been correct, but his theory is yet to be proven. Deciding whether to call an evacuation in the prediction of a volcano is also challenging, as the intensity of an eruption is tricky to tell. There are 33 recently active volcanoes in the United States, but less than half of them are monitored, according to the USGS, the government agency responsible for issuing warnings of hazardous volcanic activity. Sometimes, the USGS has to assume that a volcano will behave in the way it has in the past.

Answer 2

Volcanic prediction methods include monitoring seismic activity, gas emissions, ground deformation, and changes in temperature. Scientists also use satellite data, geological mapping, and historical eruption patterns to forecast volcanic activity. In some cases, the combination of these methods can help to provide an accurate prediction of when a volcano may erupt.
