Seismic structure of western end of the Nankai trough seismogenic zone [PDF]
Journal of Geophysical Research: Solid Earth, 2002 In 1998 a seismic experiment along a 320‐km‐long profile using an air gun array and ocean bottom seismographs (OBSs) was collected in the on shore‐offshore, forearc region of the western Nankai trough seismogenic zone, southwestern Japan. This area is outside the coseismic rupture area of the 1946 Nankaido earthquake (Ms = 8.2).

High precision earthquake locations reveal seismogenic structure beneath Mammoth Mountain, California [PDF]
Geophysical Research Letters, 2003 In 1989, an unusual earthquake swarm occurred beneath Mammoth Mountain that was probably associated with magmatic intrusion. To improve our understanding of this swarm, we relocated Mammoth Mountain earthquakes using a double difference algorithm. Relocated hypocenters reveal that most earthquakes occurred on two structures, a near‐vertical plane at 7 ...

新疆博罗可努—阿齐克库都克断裂精河段古地震与最新活动时代研究
Dizhen xuebao, 2022 博罗可努—阿齐克库都克断裂是西天山北西向右旋走滑断裂系中最北端的一条活动断裂，其在中国境内延伸最长。本文在艾比湖西侧及精河县东南侧最新地表形变上开挖两条探槽，进行该断裂古地震的初步研究。根据活动性质差异和断裂截切关系将该断裂分为艾比湖段和精河以东段，在对沉积物光释光年代和地震关系分析的基础上，确定了此两段断裂的最新活动时代均为全新世，初步确定其古地震期次，最新地震事件距今3.7—4.86 ka之间；根据冲沟位错和洪积扇年代测定结果，确定精河以东段的活动速率大于4 mm/a；根据探槽错动至地表 ...
