Answer 1

A You notice an increase in seismic activity.

Seismic activity is one of the best indicators that a volcano is about to erupt. This increase in ground shaking is often associated with the movement of magma beneath the surface, which can lead to an eruption. Monitoring seismic activity is crucial for predicting volcanic eruptions and ensuring the safety of nearby communities.
