epicentre, fault lines, seismic waves, volcanoes

Answer 1

(1) Epicentre: The epicentre of an earthquake is the point on earth's surface that is directly above the point inside the earth where the earthquake has originated.

(2) Fault lines: Fault lines are the fractures on the earth's crust along which tectonic plates move.
