Volcanic eruptions affect many populated areas. Which pieces of evidence would a geologists use to predict future eruptions?

Geologist can use the following pieces of evidence in predicting future eruption;

1)Frequency of localize Earthquakes.

2)Gas Emissions.

3)Remote monitoring.

4)History of Volcanic Activity

Explanation:

Frequency of Localize Earthquakes:Geologists use seismographs that record the length and strength of each earthquake to try to determine if an eruption is imminent.

Gas emissions:Gases may be able to escape a volcano before magma reaches the surface. Geologists measure gas emissions in vents on or around the volcano.The amounts of gases and their ratios are calculated to help predict eruptions.

Remote Monitoring:Some gases can be monitored using satellite technology. Satellites also monitor temperature readings and deformation. As technology improves, Geologist are better able to detect changes in a volcano accurately and safely.

History of Volcanic Activity:A volcano’s history, how long since its last eruption and the time span between its previous eruptions, is a good first step to predicting eruptions.

answer; i believe the answer is (25%)plz check first good luck;
