The 2004 and 2005 Sumatra Earthquakes: Implications for the Lisbon earthquake [PDF]

, 2005
The Sumatra mega-earthquake of 26 December 2004 (Mw=9.3) was the strongest earthquake in the world since the 1964 Alaska earthquake and the fifth strongest since 1900. The earthquake occurred at the interface of the India and Burma plates and triggered a

Fluid pressures at hypocenters of moderate to large earthquakes [PDF]

Journal of Geophysical Research: Solid Earth, 2001
Many active faults are expected to develop fluid pressures in excess of hydrostatic pressures below 3 to 7 km depth during interseismic periods. Suprahydrostatic fluid pressures are known to reduce the stresses required for brittle failure. Stress differences that trigger moderate to large earthquakes typically range from 40 to 160 MPa, as indicated by

Stress Field and Megathrust Strength in the Western Hellenic Subduction System: Insights From the 2024 Mw 5.9 Strofades Earthquake Sequence, Greece

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A M5.9 earthquake occurred on 29 March 2024, offshore near the Strofades Islands, in the western Hellenic Subduction System. Here we present high‐precision earthquake locations and focal mechanisms that suggest the rupture of a NNE‐SSW striking, left‐lateral strike‐slip fault.

Relocation Study of Flores Sea Hypocenter (Mw = 7.3) Based on Single Station Estimation Using ObsPy

JGEET: Journal of Geoscience, Engineering, Environment and Technology
One area in Indonesia that is prone to disasters is the Flores Sea area, which has the potential for earthquakes to trigger tsunamis. This is due to the location of Flores, which is in a subduction zone that originates from the collision of the Indo ...

Geodetic, teleseismic, and strong motion constraints on slip from recent southern Peru subduction zone earthquakes [PDF]

, 2007
We use seismic and geodetic data both jointly and separately to constrain coseismic slip from the 12 November 1996 M_w 7.7 and 23 June 2001 M_w 8.5 southern Peru subduction zone earthquakes, as well as two large aftershocks following the 2001 earthquake ...

Assessing Post‐Earthquake Emergency Healthcare Accessibility Considering Damage to Hospital Buildings and Transportation Infrastructure

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This article presents a framework for performing a regional assessment of the accessibility of emergency healthcare facilities after a major earthquake. Accessibility is assessed by applying the enhanced two‐step floating catchment area method to a regional road network, implemented in ArcGIS.

Accurate Redetermination of the Focal Depth by Using the Time Intervals between the Inner Core Phases PKIKP and pPKIKP

Applied Sciences, 2022
The hypocenter parameters of an earthquake may give us an insight into the Earth’s structure and tectonic processes. Among the hypocenter parameters, the focal depth is normally more difficult to estimate than the earthquake location (latitude and ...

Suitability of Ground‐Motion Models for Seismic Hazard Assessments in Puerto Rico and the US Virgin Islands

Earthquake Spectra, Volume 42, Issue 2, May 2026.
We perform linear mixed‐effects analyses with a ground‐motion dataset to evaluate how well ground‐motion models (GMMs) fit active crustal, subduction interface, and subduction intraslab earthquakes in Puerto Rico and the US Virgin Islands. Most of the GMMs reproduce the spatial variation in peak ground motions with earthquake magnitude and rupture ...

Near‐Source Ground Motion From Normal Faults: Insights From the Physics‐Based Numerical Simulations of the 1980 Irpinia Earthquake, Southern Italy

Earthquake Spectra, Volume 42, Issue 2, May 2026.
In this paper, the physics‐based numerical simulation of the strongest instrumental earthquake in the recent seismic history of Italy, i.e., the Nov 23, 1980 Irpinia earthquake in Southern Italy, with magnitude MW 6.8, is presented and discussed. A 3D spectral element model covering an extended region (147 × 110 km2) was constructed, with a frequency ...
