The surface where they slip is called the fault or the fault plane. The location below the Earth’s surface where an earthquake begins is called the hypocentre, and the location directly above it on the surface of the Earth is called the epicentre.

Power of Plate Tectonics: Earthquakes AMNH

WebIn an earthquake, huge masses of rock move beneath the Earth ’s surface and cause the ground to shake. Earthquakes occur constantly around the world. Often they are too small for people to feel at all. Sometimes, … WebAs with volcanoes, students may believe that earthquakes happen in random locations across the earth. Most of the world’s seismic activity is associated with tectonic plate boundaries and fault lines. While shallow crevasses may form during an earthquake due to landslides or ground failures, the ground does not “open up” along a fault line.

WebEarthquakes occur when tension/energy is released from inside the crust. Plates do not always move smoothly alongside each other and sometimes get stuck. When this happens pressure builds up. WebEarthquakes occur at the edges of the plates, and more commonly at the edges of large plates. The plate boundaries mostly lie beneath the oceans and cannot be seen. However, …

Web2. Sometimes plate edges get stuck because of friction but the rest of the plate keeps moving, very slowly. 3. The energy and pressure that move the plates get stored up at the edges. 4. When the energy and pressure build up enough to overcome the friction, the plates move past each other along the fault. 5.
