Faults in the Quaternary Deposits of the Northern Lake Ladoga Region as Indicators of Seismotectonic Processes

Abstract

Faults in Quaternary deposits that were established during field investigations indicate that seismic events with magnitude of at least 5 occurred in the Northern Ladoga region in recent time. Computer modeling data showed that the modern seismicity of this territory is associated with neotectonic activation of the Precambrian faults under the conditions of NW-directed compression. Topographic analysis allowed us to distinguish faults that confine the Ladoga Lake basin and belong to active neotectonic structures.
