Insights From Two Decades of Seismicity at Columbia Glacier

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We use Columbia Glacier as a case study to demonstrate how seismically cataloged calving events in Alaska can track glacier evolution over two decades. By combining this catalog—a serendipitous byproduct of earthquake monitoring—with terminus positions, bathymetry, glacier thickness, surface velocity, and environmental records, we show how ...

Estimation of Hypocenter of Explosion Earthquakes at Sinabung Volcano During October to December 2014

IOP Conference Series: Earth and Environment
The distribution of hypocenters for explosion earthquakes occurring at Sinabung Volcano, North Sumatra, between October 1 and December 31, 2014 have been investigated.

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor

Abrupt Along‐Strike Change of Shallow Seismicity in Central and Southern Myanmar: Insights From High‐Resolution Local‐Earthquake Catalogs and Focal Mechanisms

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Myanmar's high seismic hazard is underscored by the 2025 Mw 7.7 earthquake on the Sagaing Fault, yet its seismicity patterns and underlying controls remain poorly understood. Using new seismic data from the 2nd‐phase array of the China‐Myanmar Geophysical Survey in the Myanmar Orogen, we construct a high‐resolution catalog of 1,819 local ...

Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.

Relokasi Hiposenter Double Difference dan Penentuan Model Kecepatan di Jawa Bagian Barat

Positron
Jawa bagian barat merupakan daerah dengan seismisitas tinggi yang dipengaruhi zona subduksi dua lempeng tektonik. Seismisitas tinggi ini dipengaruhi oleh keberadaan sesar aktif yang beberapa diantaranya belum terpetakan oleh PuSGen.

Earthquake Source Depth Determination Using Single Station Waveforms and Deep Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract In areas with limited station coverage, earthquake depth constraints are much less accurate than their latitude and longitude. Traditional travel‐time‐based location methods struggle to constrain depths due to imperfect station distribution and the strong trade‐off between source depth and origin time.

Rupture Cascade Initiated by Wastewater Disposal: Nucleation and Domino Effect of Canada's Largest Induced Earthquake

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract In 2022–2023, three local‐magnitude (ML) 4.8–5.6 earthquakes shook the Peace River oilsands area of Alberta, Canada. Previous studies statistically linked the seismicity to nearby disposal activities but lacked in‐depth investigation into triggering mechanisms, including subsurface fluid migration and earthquake interaction.

Relokasi Hiposenter dan Mekanisme Sumber Gempa Bumi Danau Poso 24 Juli 2025 (Mb 6,2) di Sulawesi Tengah, Indonesia

Jurnal Pendidikan, Sains, Geologi, dan Geofisika (GeoScienceEd Journal)
An earthquake of Mb 6.2 shook the Lake Poso area, Central Sulawesi, on July 24, 2025 at 13:06:59 WIB. This study aims to examine the characteristics of the earthquake source through two approaches: hypocenter relocation using the double-difference ...

Automatic Earthquake Catalogs From a Permanent DAS Offshore Network

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Applying Distributed Acoustic Sensing (DAS) to sense offshore telecom cables offers a unique opportunity to expand permanent seismological networks far offshore with an unprecedented instrumentation density but presents challenges in managing and processing data.
