seismic activity
Earth's crust moving
Seismic activity refers to the frequency and intensity of earthquakes in a given area, or more broadly, any vibration of the earth's crust—whether from natural causes like tectonic shifts and volcanic eruptions or from human activities like mining and explosions.
The region has seen increased seismic activity in recent months.
Figuratively, seismic describes anything with massive, far-reaching impact: a seismic shift in public opinion.
