A Review of Earthquake Source Parameters in the Main Ethiopian Rift

International Journal of Geophysics, 2023
We assessed earthquake source parameters compiled from previous studies and international databases. In addition, moment tensor inversion is made from the broadband seismic data of two earthquakes that occurred in the region in 2017 and 2018 with ...

Reactivation of minor faults in a blind active fault area: A case study of the aftershock area of the 2000 Western Tottori Earthquake, Japan

Journal of Asian Earth Sciences: X, 2021
The 2000 Western Tottori Earthquake (Mw 6.6, Mjma 7.3) in Japan occurred in an area where no active faults are known to exist. We examined the distribution, occurrence, paleostress field, and K–Ar ages of minor faults in the aftershock region of this ...

Key controls on the formation of reservoirs along the ultra-deep strike-slip fault zone in the depression of the northern Tarim Basin, NW China

Petroleum Exploration and Development
Based on the data of reservoir rock cores and 3D seismic inversion for reservoir, a comprehensive analysis was conducted using in-situ U-Pb dating of calcite cements, fluid inclusions, and geochemical data of fractured-vuggy reservoirs to investigate the

Quaternary rupture of a crustal fault beneath Victoria, British Columbia, Canada [PDF]

, 2017
The seismic potential of crustal faults within the forearc of the northern Cascadia subduction zone in British Columbia has remained elusive, despite the recognition of recent seismic activity on nearby fault systems within the Juan de Fuca Strait.

The characteristics of strike-slip faults and their control on hydrocarbon distribution in deep carbonate reservoirs of the central Sichuan Basin

Frontiers in Earth Science, 2023
The past decade has witnessed a breakthrough in the gas exploration of deep marine carbonates of the central Sichuan Basin. Deep faults research has also attracted increasing attention, as faulting plays an important role in reservoir control.

Role of two-stage strike slip faulting in the tectonic evolution of the Doseo depression in the central Africa rift system

Frontiers in Earth Science, 2023
Doseo depression of Central African Rift System is an important onshore frontier area for oil and gas exploration in Africa, with rift development characterized by the dual control of fault-depression development and strike slip faulting.
