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

Rosalie Tostevin November 23, 2012

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

About

Geology for Global Development (GfGD) is a UK-based organisation, founded by Joel Gill, working to support young geologists to make an effective contribution to international development. Through this blog we’ll be sharing articles, discussions, photographs and news about our work - all relating to the application of geology to the fight against global poverty. Many of the blogs we publish are written by guest authors, allowing young geoscientists from around the world to have their say. Do get in touch if you’d like to contribute.
