Online Jump and Kink Detection in Segmented Linear Regression: Statistical Optimality Meets Computational Efficiency

open access: yesJournal of Time Series Analysis, Volume 47, Issue 3, Page 727-748, May 2026.
ABSTRACT We consider the problem of sequential (online) estimation of a single change point in a piecewise linear regression model under a Gaussian setup. We demonstrate that certain CUSUM‐type statistics attain the minimax optimal rates for localizing the change point.

Asperity‐Driven Cascading Rupture of a Mw 1.6 Induced Microearthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Studies of small earthquake (M < 2) rupture processes traditionally rely on simplified models that assume symmetric slip or point sources. Using an exceptionally dense seismic network and empirical Green's function (EGF) analysis, we investigate the complex rupture of a Mw 1.6 microearthquake induced by hydraulic fracturing.

Al2O3 in Anorthositic Slabs: A New Perspective on LLSVPs and Seismic Velocity Variations

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aluminum is a key component of crustal and mantle minerals, influencing melting and geochemical evolution within the Earth. Al2O3 exists as corundum at the surface and in upper mantle conditions, but transforms into high‐pressure phases like Rh2O3(II) at lower mantle depths, enabling stability over a wide pressure range.

The Role of Fluids in Fault Mechanics: A 16‐Year Analysis of the Irpinia Seismicity (Southern Italy)

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Fluids in the crust influence earthquake nucleation by affecting fault strength and rupture dynamics, but direct observations at seismogenic depths are rare. We study the Irpinia Fault System in Southern Italy, site of the 1980 M 6.9 earthquake, to understand how fluid overpressure, fault orientation, and regional stress control earthquake ...

Fault Kinematic Controls on the Spatio‐Temporal Proximity of the 2023 Mw 7.8‐7.7 Türkiye Earthquakes

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The mechanism governing the spatio‐temporal proximity of the 2023 Mw 7.8‐7.7 Türkiye earthquakes remains enigmatic. Here, we used dense geodetic observations integrated with dual‐fault screw dislocation, Euler‐vector‐constrained block, and strain‐rate models to investigate the interseismic kinematics and pre‐stress state of the East Anatolian ...
