Earthquake Spectra, Volume 42, Issue 3, August 2026.With the recent increases in measured ground motion records for large earthquakes, most notably the 2023 M7.8 Pazarcik earthquake in Türkiye, the potential for pervasive high velocity fault rupture propagation over an extensive fault length has been observed.

Earth, Planets and Space, 2021 The geometries (i.e., dip angles) of active faults from the surface to the seismogenic zone are the most important factors used to evaluate earthquake ground motion, which is crucial for seismic hazard assessments in urban areas. In Osaka, a metropolitan

Earth's Future, Volume 14, Issue 8, August 2026.Abstract Statistical earthquake forecasting models, such as the Epidemic‐type Aftershock Sequence (ETAS), embed decades of empirical knowledge and assumptions about earthquake triggering, clustering, and catalog completeness. In contrast, neural spatio‐temporal point process (STPP) models often treat seismicity as generic spatiotemporal data without ...

TECTONOPHYSICAL INTERPRETATION OF EARTHQUAKE FOCAL MECHANISMS OF THE ZAGROS SYSTEM
Геодинамика и тектонофизика, 2015 Structural-paragenetic and kinematic methods of tectonophysics are applied to study earthquake focal mechanisms of the Zagros system. Nodal planes of focal mechanisms are identified as L-, L′- and R-, R′-shears by the first method, whereby coordinates of

The TsuJal Amphibious Seismic Network: A Passive-Source Seismic Experiment in Western Mexico
Frontiers in Earth Science, 2021 The geodynamic complexity in the western Mexican margin is controlled by the multiple interactions between the Rivera, Pacific, Cocos, and North American plates, as evidenced by a high seismicity rate, most of whose hypocenters are poorly located.

From Risk Perception to Action: The Behavioral Forces Shaping Disaster Preparedness
Earth's Future, Volume 14, Issue 8, August 2026.Abstract The study examines the behavioral forces spanning cognitive, social, and environmental determinants that transform disaster risk perception into tangible preparedness actions. The case study at hand focuses on Bucharest, the European capital with the highest seismic risk.

Olivine friction at the base of oceanic seismogenic zones [PDF]
Journal of Geophysical Research: Solid Earth, 2007 We investigate the strength and frictional behavior of olivine aggregates at temperatures and effective confining pressures similar to those at the base of the seismogenic zone on a typical ridge transform fault. Triaxial compression tests were conducted on dry olivine powder (grain size ≤60 μm) at effective confining pressures between 50 and 300 MPa ...

New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Caldera systems commonly experience inner resurgence, which shapes patterns of volcanic activity. However, incomplete reconstructions of past ground deformation can lead to incorrect recognition of precursory signals. The Campi Flegrei caldera (Italy) provides an exceptional opportunity to address this issue as uplifted marine sediments ...

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.
