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.

Walls lined with seismic fabric, a new material with high stiffness and considerable tensile strength, could potentially keep escape routes free of debris during the evacuation of schools, hospitals, and rest homes.
