MUD VOLCANIC MANIFESTATIONS IN THE MAXIMUM SHAKING AREAS OF STRONG EARTHQUAKES

摘要

New evidence of previously unknown catastrophic Holocene earthquakes in the Elbrus region, the northern Caucasus, is reported. The remains of ancient neptune dikes, other signs of liquefaction, seismic faults, rock avalanches, landslides and dammed pond sediments have been discovered. The ages of four seismic events over the last 5,500 years have been determined by the radiocarbon dating of paleoseismic dislocations. Their recurrence interval was also estimated. The chronological comparison of ancient seismic shocks and volcanic eruptions showed that various manifestations of endogenic activity lack a direct correlation.
