Today, scientist can predict eruptions. I have been studying about the ways scientist predict so many eruptions now in days. Scientist use installing tilt meters near the dome is critical. Tilt meter detect increasing rates of deformation before eruption heavy ash balls.
A tilt meter is an instrument designed to measure very small changes from the horizontal level, either on the ground or in structure. Another term for the tilt meter is inclinometer. Some of the volcanoes signs are the number and size of earthquakes increase in and around the volcano. The ground deforms or "bulges" at the eruption site. A lot more gas comes out of the volcano. They also use seismometer to predict eruptions. Seismometer is a sensor that detects the intensity of an earthquake. Scientist would recommend evacuation of an area based on these clues when they get notice of a volcano eruption. Scientist are studying the deposits left behind. In that way they can make predictions. Before an eruption, magma moves into the area beneath the volcano and collects in a magma chamber, or reservoir. These are some clues I’ve found. There are more clues to how scientist make predictions of eruptions.GC
