An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

ENHANCING HYPOCENTER RELOCATION FOR SEISMIC HAZARD EVALUATION IN CENTRAL JAVA AND YOGYAKARTA INDONESIA: FINDINGS FROM THE BMKG EARTHQUAKE CATALOG OF AUGUST-OCTOBER 2024

Rudarsko-geološko-naftni Zbornik
We present a hypocenter relocation analysis to examine the distribution of seismicity in the Central Java and Yogyakarta regions in Indonesia. The data were obtained from the BMKG earthquake database for the period August–October 2024, covering the area ...

Seismic Exploration for Magmatic Brine Lenses: An Example From Soufrière Hills Volcano, Montserrat

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The majority of metallic ore deposits are related to processes associated with ancient or modern volcanic systems. Beyond geothermal energy production, volcanoes also represent a potential resource of critical metals, including those required for carbon‐neutral technologies. Geothermal metals occur in subsurface fluid reservoirs fed by surface

Dike‐Induced Earthquakes as Probes of the Local Stress Field Prior to the 1998 Eruption of the Piton de la Fournaise Volcano, La Réunion

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Volcano‐tectonic (VT) earthquakes generated during dike propagation provide useful constraints on stress changes in volcanic systems. During the 1998 pre‐eruptive unrest at Piton de la Fournaise, ∼600 VT earthquakes were recorded. Using manually picked first‐motion polarities and corrected station metadata, we calculated more than 400 high ...

Comparison of Seismic Performance Assessment Using Observed or Simulated Ground Motions in Seismic Hazard Analysis and Ground Motion Selection

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2449-2465, August 2026.
ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.

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 ...

Fault‐controlled uplift segmentation and crust–mantle heterogeneity in the topographic evolution of the Sındırgı Segment (Western Anatolia) ruptured during the 2025 M6.1 earthquake sequence

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Swath profile along the Sındırgı Segment. Grey curves show minimum, mean and maximum elevations, and the thick grey line shows elevation‐corrected Moho depth. Coloured circles indicate relative rock uplift from river‐profile inversion while the red curve shows cumulative uplift.

Regional Earthquake Ground Motion Simulations for Southern California With EQSIM: Insights From the 2008 Chino Hills, 2024 Highland Park, and 2021 Carson Earthquakes

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study presents physics‐based, 3D simulations using the EQSIM framework for several earthquakes in the Los Angeles region. The primary objective was to assess the ability of deterministic physics‐based ground motion simulations to reproduce the observed motions from historical events.

The Influence of Fault Rupture Velocity on Ground Motions and Building Demands in the Near‐Fault Region

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.
