Answer:

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:

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

<u>Gas emissions</u>: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.

<u>Remote Monitoring</u>: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.

<u>History of Volcanic Activity</u>: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.
