Earthquakes don’t move from place to place. Various places on earth as subject to earthquakes. Many earthquake locations are located along the edges of tectonic plates, though some quake areas are nowhere near a plates edge. So, earthquakes don’t move. Separate quakes occur in widely spread locations.

it is the shifting of the earts plates. it all depends on the shifting of the plates.

The shaking of the Earth in one location creates a compression wave in the material present at the place that the quake originates. The wave then moves through all connecting material until it has spread sufficiently to be undetectable. Because the wave is constrained to layers of material in the crust of the Earth it probably diminishes in strength in a manner proportional to the distance it travels rather than the square of the distance as waves in air usually do. The waves progress at the speed of sound in the medium present. Transitions in density can result in refraction or even reflection of the wave.

they ripple over the ground
when they want to visit other quackes
when they get together
we are in trouble
if it is under the sea
it ´s called a tsunami
