Combined Vertical and Horizontal Components of Near‐Source Earthquakes and Impact on Base‐Isolated Structures

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 781-803, March 2026.
ABSTRACT Over recent decades, the collection of seismic data has improved the understanding of near‐fault ground motion effects, which involve both horizontal and vertical components. Among the most significant effects are fault‐normal directivity, which concentrates seismic energy into an intense, long‐period pulse, and fault‐parallel fling step ...

The SCEC Community Rheology Model for the Southern California Lithosphere: Geological Framework, Ductile Flow Laws, and Preliminary Implications

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The Southern California Earthquake Center (SCEC) Community Rheology Model (CRM) comprises a three‐dimensional geologic framework model (GFM) of southern California's lithosphere, and synthetic aggregate ductile flow laws applicable to each GFM rock type under low‐strain conditions. Given temperature, volatile content, pressure, and strain rate,

Influence of the Loading Stiffness on Sheared Granular Fault Gouge, and Applicability to Slip‐Weakening Theory

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Tectonic faults can slip in a spectrum of fault slip behaviors, from aseismic slip and slow ruptures to elasto‐dynamic earthquakes. Following frictional theory, laboratory experiments have shown that the basic ingredient that may control this transition is the interaction between the fault stiffness and the surrounding elastic medium.

Fault Kinematics of the 2019–2026 Puerto Rico Earthquake Sequence: Conjugate Faulting Within a Zone of Oblique Subduction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...

Sequential Fracture Activation and Stress Evolution During EGS Stimulation at Utah FORGE Revealed by Waveform Cross‐Correlation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Mapping fracture networks in Enhanced Geothermal Systems (EGS) is essential for optimizing reservoir performance, yet complex fracture evolution during stimulation remains difficult to resolve. This study examines the evolution of microseismicity and fracture networks during stage 3 of the 2022 EGS stimulation at the Utah Frontier Observatory ...

Imaging 3D seismic velocity along the seismogenic zone of Algarve region (southern Portugal) [PDF]

, 2010
The present seismic tomographic study is focused around Algarve region, in South of Portugal. To locate the seismic events and find the local velocity structure of epicentral area, the P and S arrival times at 38 stations are used.

Constraints on fault and lithosphere rheology from the coseismic slip and postseismic afterslip of the 2006 M_w 7.0 Mozambique earthquake [PDF]

, 2012
The 2006 M_w 7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane (~75°). The amount of slip in the earthquake decreased from depths of ~10 km toward the surface, and this shallow slip deficit was at least

Integrating GNSS and Hydrological Data to Understand Seasonal Microseismicity at La Soufrière de Guadeloupe

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract La Soufrière de Guadeloupe volcano exhibits microseismic activity dominated by volcano‐tectonic repeaters, mainly occurring in swarms clustered in a sub‐vertical conduit beneath the Tarissan acid lake (TAS) at depths less than 800 m. Following the April 2018 earthquake (Mlv 4.1), which likely damaged the dome, swarms intensified and show ...

CRISP-EQ: Costa Rican Seismogenic potential outlined by IODP drilling and the 2002 Osa earthquake sequence [PDF]

, 2011
Interplate earthquakes in subduction zones are generated in the seismogenic zone, i.e. the segment of the plate boundary where unstable slip occurs.

Rapid Seismic and Infrasound Assessment of Large Landslides: A Case Study From Denali National Park and Preserve (Alaska)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Large, rapid landslides are a global hazard that can occur in remote, mountainous areas. Eyewitness reports of landslides and satellite imagery can often be limited or delayed, particularly during inclement weather. However, landslide‐generated seismic and infrasound (low‐frequency atmospheric sound) waves can be remotely detected in near real‐
