WebEarthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake. Such movement on the faults is generally a response to long-term deformation and the buildup of stress. WebWith S waves, the particle motion is transverse to the direction of travel and involves a shearing of the transmitting rock. Because of their greater speed, P waves are the first to … dutch oven handle lifter

WebEarthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake. During and after the earthquake, the plates or blocks of rock start moving—and they continue to move until they get stuck again. 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 … WebMost earthquakes are caused by changes in the Earth’s outermost shell, or crust. The crust is made up of about a dozen rock masses called plates that are constantly moving.
