Correlation of the slope of the initial part of P-wave envelope, hypocenter depth and plate boundary

Geodesy and Geodynamics, 2018
We investigated correlation of the slope of the initial part of P-wave envelope, hypocenter depth and plate boundaries by B-Δ method, which is used to determine epicentral distances in the Japan Meteorological Agency and Japan Railway Company earthquake ...

Rupture process of the recent large Sumatra earthquakes: 26/12/2004 (Mw=9.3) and 28/03/2005 (Mw=8.6) [PDF]

, 2005
The Sumatra mega-earthquake with magnitude 9.3 of 26 December 2004 was the strongest earthquake in the world since the 1964 Alaska earthquake and the fourth since 1900.

Contemporary Seismicity in and Around the Yakima Fold-and-Thrust Belt in Eastern Washington [PDF]

, 2012
We examined characteristics of routinely cataloged seismicity from 1970 to the present in and around the Yakima fold-and-thrust belt (YFTB) in eastern Washington to determine if the characteristics of contemporary seismicity provide clues about regional ...

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 ...

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 ...

Re-Analysis of HFT Data Using the Apollo Lunar Surface Gravimeter Data [PDF]

, 2008
Introduction: The Apollo Passive Seismic Experiment (PSE) was carried out on Apollo 12, 14, 15 and 16. Network observations of four seismic stations were performed for five years from 1972 to 1977. The PSE was a successful mission that informed us of the

Behavior of Coastal Amagmatic Geothermal Systems: Thermal–Hydraulic Modeling Insights From La Jolla Beach, Baja California, Mexico

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Amagmatic geothermal systems in coastal locations are promising energy resources, yet the processes that localize and sustain their hot‐spring discharge remain unclear. We investigate La Jolla Beach (NW Baja California, Mexico)—one of the hottest known examples worldwide (∼100°C)—using large‐scale 3D coupled thermal–hydraulic simulations.

A Comparative Study of the Sumatran Subduction-Zone Earthquakes of 1935 and 1984 [PDF]

, 2002
A M_s 7.7 earthquake struck the western, equatorial coast of Sumatra in December 1935. It was the largest event in the region since the two devastating giant earthquakes of 1833 and 1861.

Dynamic Earthquake Source Inversion With Generative Adversarial Network Priors

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Dynamic earthquake source inversion consists of inferring frictional parameters and initial stress on a fault consistent with recorded seismological and geodetic data and with dynamic earthquake rupture models. In a Bayesian inversion approach, the nonlinear relationship between model parameters and data requires a computationally demanding ...

A General Framework for Multivariate Functional Principal Component Analysis of Amplitude and Phase Variation

, 2018
Functional data typically contains amplitude and phase variation. In many data situations, phase variation is treated as a nuisance effect and is removed during preprocessing, although it may contain valuable information.
