Anisotropy, focal mechanisms, and state of stress in an oilfield : passive seismic monitoring in Oman [PDF]

open access: yes, 2005
Knowledge of the spatial characteristics of stress and fractures in reservoirs is important for optimising production and injection processes. Serni-permanent passive microseismic monitoring is being conducted in the Yibal field, Oman, to better ...

Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints

open access: yesStructural Concrete, EarlyView.
Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

The July 14, 2025 Mw 5.3 earthquake in the NE Alboran Sea (Spain): insights into the causative source from seismic relocation and moment tensor analysis

open access: yesFrontiers in Earth Science
On 14 July 2025, an Mw 5.3 earthquake occurred in the northeastern Alboran Sea, Spain. Its epicenter was close to the Eastern Betics Shear Zone, a region that has historically experienced major destructive earthquakes, including events with macroseismic ...

The challenges of GFRP RC beam design for limit states

open access: yesStructural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

The Multilevel Implications of a Sinn Féin Government in Ireland

open access: yesThe Political Quarterly, Volume 96, Issue 1, Page 173-179, January/March 2025.
Abstract The electoral growth of Sinn Féin on both sides of the Irish border has generated much political and academic attention in recent years. The party could form part of the government in Dublin for the first time at the next Irish general election, though that outcome is far from certain.

An unexplained tsunami: Was there megathrust slip during the 2020 Mw7.6 Sand Point, Alaska, earthquake?

open access: yesSeismica
On October 19, 2020, the Mw7.6 Sand Point earthquake struck south of the Shumagin Islands in Alaska. Moment tensors indicate the earthquake was primarily strike-slip, yet the event produced an enigmatic tsunami that was larger and more widespread than ...

Looking at Us Through Their Eyes. The Analytical Process from Ethnographic Perspectives1

open access: yesJournal of Analytical Psychology, EarlyView.
Abstract This article looks at the analytical situation through the Others’ eyes—through examples from contemporary ethnographies of foreign cultures. It discusses the following issues: a) The analogy between the ontological worlds of the dead, ghosts, animals and dreams in “primitive populations” and the analytical psychological descriptions of the ...

Resolving a complex seismic moment tensor into a series of simple double couple sources: A case of Turkey

open access: yes, 2011
The main goal of studying double couple sources in seismology is to obtain a complete description of the physics of the source. In other words, it is to describe the force system equivalent to physical mechanism in earthquake focus. Seismic moment tensor
