Geophysical Investigations of the Structure and Tectonics of Southern California [PDF]

, 1978
Regional variations in the crustal structure of southern California are defined by travel-time data from natural and artificial events. We show that the crust of the Mojave, northeastern Peninsular Ranges, eastern Transverse Ranges and Colorado Desert ...

Mapping finite-fault earthquake slip using spatial correlation between seismicity and point-source Coulomb failure stress change

Seismica
Most earthquake energy release arises during fault slip many kilometers below the Earth’s surface. Understanding earthquakes and their hazard requires mapping the geometry and distribution of this slip.

A Hybrid Framework Combining Physical and Data‐Driven Models for Predicting the Timing of Fault Instability

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Reliable prediction of earthquakes and rock mass failure has long been hampered by a fundamental trade‐off: achieving both a long warning window and high prediction accuracy. Physical models, such as the failure forecast method (FFM) based on the time‐reversed Omori law, can provide longer warning windows but are sensitive to data noise and ...

Role of a Hidden Fault in the Early Process of the 2024 Mw7.5 Noto Peninsula Earthquake

Geophysical Research Letters
The 2024 Mw 7.5 Noto Peninsula, Japan, earthquake was initiated within the source region of intense swarm activity. To reveal the mainshock early process, we relocated the earthquake hypocenters and found that many key phenomena, including the mainshock ...

Diminishing high‐frequency directivity due to a source effect: Empirical evidence from small earthquakes in the Abruzzo region, Italy

Geophysical Research Letters, 2016
The aim of this study is to investigate the directivity effects of ~250 aftershocks (magnitudes 3–5.5) of the Mw 6.1 2009 L'Aquila earthquake (central Italy).

A Likelihood‐Free Framework for Seismic Forecasting Models: Application to Incomplete ETAS Model via Simulation‐Based Inference

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Recent advances in deep‐learning‐based earthquake detection have revolutionized seismology, producing high‐resolution catalogs complete down to very low magnitudes. While these data sets offer an unprecedented view of seismic triggering, their massive scale and inherent short‐term incompleteness pose a major challenge for traditional ...

Foreshocks, Aftershocks, and Earthquake Probabilities: Accounting for the Landers Earthquake [PDF]

, 1994
The equation to determine the probability that an earthquake occurring near a major fault will be a foreshock to a mainshock on that fault is modified to include the case of aftershocks to a previous earthquake occurring near the fault.

Real-Time Foreshock–Aftershock–Swarm Discrimination During the 2025 Seismic Crisis near Santorini Volcano, Greece: Earthquake Statistics and Complex Networks

Geosciences
The advanced determination of the type (foreshock–aftershock–swarm) of an ongoing seismic cluster is quite challenging; only retrospective solutions have thus far been proposed.

Interseismic Strain Accumulation and Partitioning in Hispaniola From GNSS and InSAR

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We combine GNSS and InSAR observations to constrain the spatial distribution of strain across the northeastern Caribbean plate boundary, focusing on Hispaniola, to investigate strain partitioning and fault slip rates in an actively deforming tectonic setting with significant seismic hazard.

Dynamic behaviour of a concrete building under a mainshock–aftershock seismic sequence with a concrete damage plasticity material model

Geomatics, Natural Hazards & Risk, 2016
The aim of this paper was to investigate the dynamic response of a concrete structure subjected to a mainshock–aftershock seismic sequence. In the dynamic analysis, three components of the registered mainshock and aftershock were taken into account.
