Equal spacing of strike-slip faults [PDF]

open access: yesInternational Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1976
Summary Strike-slip fault systems on continents frequently occur in groups of several roughly equally-spaced faults. In this article these systems are simulated by a model. A physical mechanism is then presented, which appears to explain the phenomena shown by the model both qualitatively and to a certain extent quantitatively.

Major Strike-Slip Faults Identified Using Satellite Data in Central Borneo, SE Asia

open access: yesGeosciences, 2018
We use freely available Google satellite data, instrumental seismicity, fault plane solutions, and previously mapped structural and geological maps to identify new fault zones in central Borneo.

Investigating the Deformation and Failure Mechanism of a Submarine Tunnel with Flexible Joints Subjected to Strike-Slip Faults

open access: yesJournal of Marine Science and Engineering, 2021
Knowledge from historical earthquake events indicates that a submarine tunnel crossing active strike-slip faults is prone to be damaged in an earthquake. Previous studies have demonstrated that the flexible joints are an effective measure for a submarine

Tectonic Implication of the 5th March 2005, Doublet Earthquake in Ilan, Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2016
The 5th March 2005 earthquake doublet focal mechanism was determined as strike-slip faulting from Harvard and BATS moment tensor inversion. However, based on first motion polarities, the first shock has a normal focal mechanism (Wu et al. 2008a).

The El Tocuyo, Venezuela, earthquake of 3 August, 1950: Focal parameters and tectonic implications [PDF]

open access: yesGeofísica Internacional, 2001
The El Tocuyo earthquake of 1950 event was associated with the Boconó fault system. The Ms magnitude was 6.3; the focal depth was ( from pP – P and sP – P) 18 ± 1 Km.

Complex microseismic activity and depth-dependent stress field changes in Wakayama, southwestern Japan

open access: yesEarth, Planets and Space, 2018
We examined the spatial relationship between seismicity and upper crustal structure in the Wakayama region, northwestern Kii Peninsula, Japan, by investigating microearthquake focal mechanisms and the local stress field.

Volcano instability induced by strike-slip faulting

open access: yesBulletin of Volcanology, 2000
Analogue sand cone experiments were conducted to study instability generated on volcanic cones by basal strike-slip movement. The results of the analogue models demonstrate that edifice instability may be generated when strike-slip faults underlying a volcano move as a result of tectonic adjustment.

Tiechanshan-Tunghsiao anticline earthquake analysis: Implications for northwestern Taiwan potential carbon dioxide storage site seismic hazard

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2017
We analyze the seismicity and earthquake focal mechanisms beneath the Tiechanshan-Tunghsiao (TCS-TH) anticline over the last two decades for seismic hazard evaluation of a potential carbon dioxide storage site in northwestern Taiwan.
