The results of seismological observations in the Lena River delta in 2024–2025

Abstract

The article presents the results of detailed seismological observations in the Lena River delta area using a record number of 15 temporary stations in this area. During the period from August 2024 to February 2025, signals from 326 earthquakes were isolated and processed from continuous recordings. The vast majority of hypocenters are confined to fault structures located in the northern part of the Kharaulakh ridge. The positive effect of the network's thickening points around this area is clearly demonstrated: a large number of weak earthquakes have been recorded, and local seismicity zones are clearly separated on the vertical sections.
