Julian Alps are characterised by a moderate to high seismic activity that has included several destructive earthquakes, such as the 1511 AD “Idrija” earthquake (MSK = X). Accurate assessment of the seismic hazard is required to reduce the high vulnerability of this region. Earthquake shaking may destabilise previously deposited sediment, which slides to the bottom of the lake and formed seismically induced mass wasting deposits (MWD), such as turbidites or homogenites.
