WebEarthquakes happen every day all over the world, along both tectonic plate edges and interiors. Earthquakes occur along faults, which are fractures between blocks of rock that allow the blocks to move relative to one another. Faults are caused by the bumping and sliding that plates do and are more common near the edges of the plates. WebWe are truly in motion no matter where we stand on the planet. The tectonic plates that compose the crust of the Earth are in motion at a measurable rate. Everything on the crust …
