Geomechanical Conditions of Seismic, Volcanic, and Hydrothermal Activity in Kamchatka

Key Points

This research aims to investigate the geomechanical conditions that influence seismic and hydrothermal activity in Kamchatka.
Utilized Frac-Digger method to calculate the distribution and orientation of seismogenic faults based on seismic data catalogs.
Analyzed Mohr–Coulomb diagrams to identify three main geomechanical states affecting fault activity.
Identified three active geomechanical states: NWW horizontal extension at 300° azimuth, horizontal radial extension, and horizontal radial compression.
Determined that hydrothermal explosions can occur when pore pressure exceeds rock mass stress values.

Abstract

The distribution and orientation of regional seismogenic faults of Kamchatka are calculated by Frac-Digger method based on seismic data catalogs of the Kamchatka Branch of the Federal Research Center United Geophysical Survey, Russian Academy of Sciences. The analysis of Mohr–Coulomb diagrams shows three main geomechanical states, when the regional seismogenic faults can be active: NWW horizontal extention at an azimuth of 300°, horizontal radial extention, and horizontal radial compression. Hydrothermal explosions occur, when the pore pressure exceeds the stress values in the rock mass.
