METHOD OF DETERMINING POTENTIALLY EARTHQUAKE-PRONE ZONES Russian patent published in 2024 - IPC G01V1/01 G01V9/00 

Abstract RU 2827540 C1

FIELD: seismology.

SUBSTANCE: invention relates to seismology and can be used to determine potentially earthquake-prone zones. Investigated territory is divided into quasi-homogeneous geodynamic blocks with transverse dimensions of 30 km. Geological survey is carried out on these blocks with mapping of traces of paleoseismic events and geophysical investigations by the method of reflected waves to clarify the spatial position and geometric dimensions of geological structures. Field material is processed in a cameral process with the help of stock material to obtain values of geoseismological parameters. At that, for each geodynamic block, the obtained values of geoseismological indicators are estimated in standard units from 0 to 1. Geoseismological indicators include thickness of the earth's crust, length of disjunctive zones and sedimentary cover, area of propagation of traces of paleoseismicity, thickness of seismically active layer, seismic activity, maximum magnitude, period of last activation and tectonic activity. Seismic potential is determined for each geodynamic block with due allowance for geoseismological indices evaluated by experts. Map of seismic potentials of geodynamic blocks is made, on which seismogenic structures active at the current geological stage of development of the region are identified and potentially seismically hazardous zones are determined.

EFFECT: high accuracy and information content of determining potentially earthquake-prone zones.
