Question

Quizplus · Accepted Answer

Ground deformation, or changes in the shape and elevation of the ground, can occur as magma rises and accumulates beneath the surface, indicating a potential volcanic eruption. Seismic waves and gas emissions are also common precursors to volcanic activity. Flash floods, landslides, human anxiety, and unusual animal behavior are not reliable indicators of imminent volcanic eruptions.
