Friday Photo (64): Geologists in the field – snow in Greece
After our successful ‘active geology’ series, we begin a new, fun photo series looking at ‘geologists in the field’. This week, clearing snow off the outcrop on an undergraduate field trip to Greece, December 2009. Please send us your favourite field photos! (c) Geology for Global Development
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
Friday Photo (57): Active Geology – Sinking Buildings from Ancient Greece
These foundations were once part of a building in ancient Greece. Over thousands of years, active faults have lowered the land and the foundations have sunk below sea level. Geology can have a big impact on relatively short timescales. (c) Geology for Global Development
