Earthquakes form seismic waves
Weball types of faults can generate earthquakes: normal fault, reverse fault, thrust fault, strike-slip fault As it grows, a fault rupture that began at depth: has an oval shape below the surface What is NOT true about seismic waves? The material within the wave moves long distances along with the wave. WebIn the form of seismic waves (like water ripples), the escaping energy radiates outward from the fault in all directions. The seismic waves shake the earth as they move through …
