3. Submitted by : Jaideep kaur tiwana How Do The Earthquakes In New Zealand And Nepal Compare? The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. Natural cause: Earthquakes are the result of slow-moving processes that operate within Earth. Usually we only feel the bump and rattle of these waves. These vibrations pass through the earth’s surface in waves and cause the earthquake. Sometimes animals can hear the P waves of an earthquake.
