Earth and Planetary Physics, 2018 The 13 November 2016 Kaikoura earthquake occurred in the northeastern coastal region of the South Island, New Zealand. The Mw 7.8 mainshock generated a complex pattern of surface ruptures, and was followed within about 12 hours by three moderate shocks ...

Asperity‐Driven Cascading Rupture of a Mw 1.6 Induced Microearthquake
Geophysical 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.

hypoDD-A Program to Compute Double-Difference Hypocenter Locations [PDF]
Open-File Report, 2001 HypoDD is a Fortran computer program package for relocating earthquakes with the double-difference algorithm of Waldhauser and Ellsworth (2000). This document provides a brief introduction into how to run and use the programs ph2dt and hypoDD to compute double-difference (DD) hypocenter locations.

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

Characteristics of Seismic Energy Rate Functions of Shallow Tremors
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract We investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (<104 J) shallow tremors. As the seismic radiated energy increases, the energy rate functions become more complex and are better ...

Surface rupture and shallow fault reactivation during the 2019 Mw 4.9 Le Teil earthquake, France
Communications Earth & Environment, 2020 The 2019 Le Teil earthquake in southern France reactivated an existing fault and ruptured the surface, according to field, seismic and InSAR observations. The incredibly shallow hypocenter can explain the effects of the moderate Mw 4.9 event.
