Experience of Complex Microseismic and Magnetotelluric Sounding on the Northern Part of the Central Sikhote-Alin Fault

A study of the Central Sikhote-Alin Fault (CSAF) reveals that its fault zone is impermeable, characterized by a narrow subvertical high-resistivity region between contrasting crustal blocks. Researchers used microseismic sounding (MSS) and magnetotelluric sounding (MTS) to map relative P-wave velocities and geoelectric structures up to 9 km deep along a 42 km transect. The findings show that the CSAF's structure aligns with another fault zone 6 km northwest, extending deeper than initially observed. This dual-method approach demonstrates promise for unraveling crustal dynamics in tectonically active regions.
