Abstract

In this work we investigated the indicators of NW-trending hidden faults in the Priamurye region. Four major fault zones and a series of lower-rank faults were mapped, which have been revealed from the relief lineaments, magnetic anomalies, and arranged earthquake foci sequences. In the region, the NW-trending faults control the block divisibility of the upper part of the lithosphere and appear to be currently seismically active. Two NW-trending hidden faults are characterized by the considerable amount of the seismic energy they released, which should be taken into account during the seismic hazard assessment of the region.

通过地形分析和地球物理场绘制 Priamurye 地区 NW 向隐藏断层图

摘要

在这项工作中，我们调查了 Priamurye 地区 NW 向隐藏断层的指标。绘制了四个主要断层带和一系列下级断层，这些断层从地势线、磁异常和地震震源序列中得到了揭示。在该地区，NW 向的断层控制着岩石圈上部的块体可分性，目前似乎地震活跃。两条 NW 向隐藏断层的特点是它们释放的地震能量相当可观，在对该地区进行地震危险性评估时应考虑到这一点。
