A paleoseismological trench has been opened at San Carlo – Sant’Agostino. At this place, liquefaction features and other environmental earthquake effects were recognized after the Finale Emilia earthquake of 2 May 2012, magnitude MW6.1. The trench reveals normal fault features close to the surface. Our colleague Alex Chatzipetros from Earthquake Geology of Greece posted a great article on the trench work and has all the interesting photos.
The 55 m long trench was opened by Riccardo Caputo, Sotiris Sboras, Marco Stefani and Kyriaki Iordanidou. We are excited to see more data soon. Read Alex’ article at his blog.
