How do scientists predict volcanic eruptions?

Scientists predict volcanic eruptions by monitoring various geological and geophysical signals. These include tracking earthquake tremors, which indicate the upward movement of magma, and using tiltmeters to detect ground deformation as magma chambers fill. Other methods involve laser measurements of slope changes, temperature monitoring, gas detection, and instruments sensitive to variations in magnetic and gravity fields. Permanent volcano observatories at active sites continuously monitor these indicators to provide early warnings. Studying past eruptions also helps estimate future hazards. While forecasting is improving, it still involves uncertainty, making timely evacuations crucial.12
