A blind thrust earthquake occurs along a thrust fault that does not show signs on the Earth's surface, hence the designation "blind". [1] Such faults, being invisible at the surface, have not been mapped by standard surface geological mapping.

2024年12月28日 · We demonstrate that the Hualien earthquake occurs on a blind listric fault, manifesting as a unilateral rupture primarily extending toward the NNE. The slip distribution exhibits a compact...

What is a fault and what are the different types? A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.

A thrust fault that does not rupture all the way up to the surface so there is no evidence of it on the ground. It is buried under the uppermost layers of rock in the crust.

2022年1月19日 · 隐伏或埋藏活断层 (Buried or concealed ac-tive fault): 包括两类， 一类 是被第四纪松散沉积物覆盖的，在 地表 没有醒目形迹的活动断层； 另一类 是在地表变形后，变形形迹又被后期沉积物 完全覆盖 的断层。

2017年10月24日 · We use seismic waveforms and interferometric synthetic aperture radar (InSAR) to determine the fault parameters and slip distribution of the 2015 M w 6.3 Pishan earthquake—a blind, reverse-faulting event dipping toward the Tibetan Plateau. Our earthquake mechanism and location correspond closely to a fault mapped independently by seismic ...

2022年6月11日 · Here we investigated the Pichilemu Fault in coastal Chile, unknown until it generated a Mw 7.0 earthquake in 2010. The lack of evident surface faulting suggests activity along a partly-hidden...

2021年5月21日 · By an integrated analysis of the inversions, aftershock sequence and tectonic feature of the regional faults, we proposed that a blind branch fault splaying from the Weixi-Qiaohou-Weishan fault at depth or a new unknown blind …

2022年2月1日 · Blind active faults may lead to earthquake, therefore their identification and characterization constitute an important structural exercise. Such faults can be mapped by high-resolution shallow subsurface geophysical techniques, which offer …

2018年4月30日 · We propose that most fault slip rate variability across a range of time and spatial scales is due to intrinsic faulting processes, rather than extrinsic changes in surface loads or stress boundary conditions.
