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 ...

Predictability in the ETAS Model of Interacting Triggered Seismicity

, 2003
As part of an effort to develop a systematic methodology for earthquake forecasting, we use a simple model of seismicity based on interacting events which may trigger a cascade of earthquakes, known as the Epidemic-Type Aftershock Sequence model (ETAS ...

Some characteristics of foreshocks and aftershocks of the 2022 ML6.8 Chihshang, Taiwan, earthquake sequence

Frontiers in Earth Science
Foreshocks and aftershocks occurred before and after the ML6.8 (Mw7.0) earthquake in eastern Taiwan on 18 September 2022. We explore the epicentral distribution and temporal variations for the mainshock, foreshocks, and aftershocks.

Seismicity and Seismotectonics in the Cantabrian‐Pyrenean Zone (N Spain) Using a Dense Temporary Network of Broadband Seismic Stations

Tectonics, Volume 45, Issue 3, March 2026.
Abstract Earthquakes in intraplate regions are often scattered and difficult to associate with specific geological structures, requiring detailed surveys to identify active faults. Improving knowledge of local seismicity in these areas is essential for accurate seismic hazard assessment and for safe planning of economic activities that could affect ...

Apparent Clustering and Apparent Background Earthquakes Biased by Undetected Seismicity

, 2005
In models of triggered seismicity and in their inversion with empirical data, the detection threshold m_d is commonly equated to the magnitude m_0 of the smallest triggering earthquake. This unjustified assumption neglects the possibility of shocks below

An exploration of the relative influence of physical models for Omori’s law

Frontiers in Earth Science
Omori’s law states that the rate of aftershocks decays as a function of inverse time. There are multiple physical explanations that we reduce into a nonlinear mixed effects relation of three terms: (1) a Rate/State expression that can account for static ...

Homological Correspondence: Israel as a Frontier of Global Domination

Antipode, Volume 58, Issue 2, March 2026.
ABSTRACT This article offers a novel framing for enquiring the deep entanglement between Israel and Western‐led global centers of domination. Moving beyond geopolitical reasonings and historical analogies, it locates this relationship within a dynamic space of homological correspondence, positioning Israel as its frontier.

Multivariate representations of univariate marked Hawkes processes

Scandinavian Journal of Statistics, Volume 53, Issue 1, Page 140-174, March 2026.
Abstract Univariate marked Hawkes processes are used to model a range of real‐world phenomena including earthquake aftershock sequences, contagious disease spread, content diffusion on social media platforms, and order book dynamics. This paper illustrates a fundamental connection between univariate marked Hawkes processes and multivariate Hawkes ...

High‐Precision Aftershock Distribution Highlights the Complex Fault Geometry of the 2024 Mw 7.5 Noto Peninsula Earthquake

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We deployed 30 temporary seismic stations around the source region of the 2024 Mw 7.5 Noto Peninsula earthquake to investigate the relationship between mainshock rupture and fault geometry. Using machine learning techniques, we detected and precisely located 46,252 aftershocks, revealing several fault planes corresponding to active faults ...

Comment on "Analysis of the Spatial Distribution between Successive Earthquakes" by Davidsen and Paczuski

, 2006
By analyzing a southern California earthquake catalog, Davidsen and Paczuski [Phys. Rev. Lett. 94, 048501 (2005)] claim to have found evidence contradicting the theory of aftershock zone scaling in favor of scale-free statistics. We present four elements
