A change in the frequency of earthquakes may foretell explosive volcanic eruptions. The seismic activity changes from steady drum beats to increasingly rapid successions of tremors.

Io [EYE-oh or EE-oh] is the most volcanic world in the Solar System, and scientists think it's because of a torrid reservoir of magma under the crust at least 30km (50 miles) thick.
In the restored San Gennaro Catacombs, mosaics of jaw-dropping beauty glisten under high-tech lighting. Tombs that once housed the remains of Christian saints and martyrs are carved right into hardened volcanic ash.

Riddling the side of Mt. Erebus are ice caves, carved out by escaping volcanic gases. While the inside may be extremely hot, outside of it one would quickly freeze to death in the Antarctic temperatures.
