The Wednesday Centerfault (1)

It’s not easy to prepare weekly Friday links when you are abroad, this is what I had to realize in April. However, I will try to post a natural beauty each Wednesday in the future, the Wednesday Centerfaults and Centerfolds.

Today, I start with the Kaparelli Fault in Greece (38.22°N, 23.23°E). This beautiful limestone fault scarp is more than 2.5 km long and up to 5 m high. The fault was activated during the 1981 Corinth earthquakes. On the image, our LiDAR is scanning the scarp surface for roughness investigations. The vertical scars are due to sampling for OSL dating, published by Benedetti et al., 2003. The fault has also been trenched: Kokkalas et al. (2007) proposed three events within the last 10 ka before the 1981 EQ series.
