WebScientists now believe that the crust of the Earth consists of rigid interconnecting plates (6 major plates and a few smaller ones). Plates are thought to float on the partially molten mantle, moving away from oceanic ridges where new plate material is produced and moving past each other or colliding along plate boundaries. WebJan 11, 2024 · Transform plate boundaries produce enormous and deadly earthquakes. These quakes at transform faults originate at shallow foci. This is because the plates slide past each other without moving up or down. The San Andreas Fault that runs through much of California is an enormous transform plate boundary.

WebEarthquakes occur along the boundaries between tectonic plates or at the site of cracks within the plates, which are called faults. What causes earthquakes? The tectonic plates … 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.
