Earthquake and Tsunami NaTech Risk Assessment for Oil Storage Facilities

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1887-1904, 25 July 2026.
ABSTRACT Interaction of natural and technological hazards (NaTech) events, such as tsunamis and earthquakes, can affect industrial facilities such as those featuring anchored atmospheric storage tanks. Consequences of natural events on this kind of installation may include the release of hazardous substances, which in turn can lead to industrial ...

Unraveling the Source Locations of Short‐Period Secondary Microseisms

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Primary and secondary microseisms are generated by ocean wave interactions, with the latter occasionally split into short‐ and long‐period bands in some regions. The short‐period secondary microseism (SPSM) sources have traditionally been associated with nearby coastal segments, suggesting a more uniform distribution across shorelines.

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Source parameters, focal mechanisms and stress tensor inversion from moderate earthquakes and its relationship with subduction Zone

Geofísica Internacional, 2019
En este trabajo se relocalizaron 9 sismos ocurridos entre 2005 y 2009, con magnitudes entre 4.9 y 5.5, en la zona que corresponde a la triple unión de las placas de Cocos, Rivera y Norte América. Se utilizaron los registros de la estación sísmica RESCO y

Fluid‐Driven Cohesive Strengthening: Critical Role of Reaction Kinetics as the Determinant for Frictional Stability

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

Geomechanical rock properties of a basaltic volcano

Frontiers in Earth Science, 2015
In volcanic regions, reliable estimates of mechanical properties for specific volcanic events such as cyclic inflation-deflation cycles by magmatic intrusions, thermal stressing, and high temperatures are crucial for building accurate models of volcanic ...

Multidisciplinary Investigation of Healy Submarine Volcano (Kermadec Arc, New Zealand) Using AUV and Submersible Data: Structural Control on Magmatic and Hydrothermal Processes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract We present a comprehensive multidisciplinary investigation of the Healy submarine volcano in the southern Kermadec arc, northeast of New Zealand. We show the first results of sidescan‐sonar data collected at a submarine arc volcano by an Autonomous Underwater Vehicle (AUV).

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...

Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...
