Friday Photo (58): Active Geology – Striations on a Fault Surface, Greece

  An active fault surface in Greece – one of the most seismically active places on Earth. The striations on the surface can be used to measure the direction of movement on the fault. The exposed surface can be dated at various heights (using dating systems such as Beryllium-10) to infer the rate of slip. (c) Geology for Global Development
