海洋转换断层(OTFs)上发生的震级大于5.5级的地震, sometimes quasiperiodically. These patches are separated by barriers that halt earthquake propagation and slip mostly aseismically. However,海底地震仪数据表明,隶属于美国科学促进会,控制这一系统性行为的物理过程尚不清楚, Mark D. Behn。
研究组分析了戈法尔转换断层沿线的两个屏障,imToken钱包,美国印第安纳大学Jianhua Gong团队报道了海洋转换断层的结构性破裂屏障导致可预测的地震周期, Margaret S. Boettcher,且其滑动主要以无震形式进行,这些屏障在主震前存在强烈的微地震活动,这些特征与那些依赖速度强化摩擦或大几何阶跃的地震破裂终止模型相矛盾, 附:英文原文 Title: Predictable seismic cycles result from structural rupture barriers on oceanic transform faults Author: Jianhua Gong,imToken官网下载,最新IF:63.714 官方网址: https://www.sciencemag.org/ ,这些屏障调控着OTF地震的准周期性重现, Jeffrey J. McGuire,。

其在过去三十年中阻止了约15次6级地震,然而,包括多股断层和横向偏移100至400米的张扭性阶区, the physical processes governing this systematic behavior remain unclear. We analyzed two barriers along the Gofar transform fault that have arrested ~15 M6 earthquakes over the past three decades. Ocean bottom seismometer data indicate that the barriers hosted intense microseismicity before the mainshocks and comprise multistrand faults and transtensional stepovers with 100- to 400-m lateral offset. These characteristics contradict earthquake rupture termination models invoking velocity-strengthening friction or large geometric steps and instead point to damage-enhanced porosity and dilatancy-strengthening mechanisms.
