Long-term slow slip events with and without tremor activation in the Bungo Channel and Hyuganada, southwest Japan

Earth, Planets and Space, 2023
Slow slip events (SSEs) lasting for approximately 1 year occur every 6–8 years around the Bungo Channel in the southwest Japan subduction zone. The slip time evolution of the latest Bungo Channel SSE that occurred in 2018–2019 has been studied; however ...

A Spatio‐Temporal Neural Kernel Function Model for Earthquake Clustering: Bridging ETAS and Neural Point Processes

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Modeling earthquake clustering in space and time is central to understanding seismicity patterns and improving forecasting. The Epidemic‐Type Aftershock Sequence (ETAS) model, grounded in the Hawkes process, has long been the standard approach for describing aftershock triggering through fixed, empirically defined kernel functions.

Event Size Distribution of Shallow Tectonic Tremor in the Nankai Trough [PDF]

Geophysical Research Letters, 2019
AbstractSlow earthquake size distributions have been found to follow either a power law or an exponential law, depending on the data set. We investigated the size distribution of shallow tectonic tremor events along the Nankai trough, southwestern Japan, observed in 2009, 2015, 2016, and 2018 and estimated the seismic energy radiated during the events ...

Erupted Volume During the 2014–2023 Semisopochnoi Unrest and Eruption Constrained by Multi‐Platform InSAR and Volcanic Gas Observations

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Volcano deformation data provide important constraints on magma dynamics during volcanic unrest and eruptions. From these observations, we can estimate subsurface pressure changes and relate them to volume change in the reservoir. However, because magma and rock are compressible, this volume change cannot be directly equated with eruptive ...

Unusual Wrist Tremor: Unilateral Isometric Tremor? [PDF]

, 2014
Background: Tremors may be difficult to classify.Case Report: An 83‐year‐old male presented with an unusual left wrist tremor. The tremor could be reproducibly elicited by making a fist or carrying a weighted object (e.g., a shopping bag ...

Fault–fracture mesh development produces tectonic tremor in fluid-overpressured serpentinized mantle wedge

Communications Earth & Environment
Deep tectonic tremor occurs repeatedly at the base of a forearc mantle wedge corner, where a highly fluid-pressurized serpentinite shear zone is thought to develop.

A Simple Discrete Elastic Model Exhibits Both the Statistical Properties and Migration Patterns of Slow Slip

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract More than 20 years after their discovery, the physical mechanisms of slow earthquakes remain enigmatic. Here, we develop a simple quasi‐static elastic model that reproduces both the migration patterns of elastic/frictional models, and the statistical properties of Brownian models.

Early Head Tremor in Essential Tremor: A Case Series and Commentary [PDF]

, 2017
Background: Classically, the onset of head tremor in essential tremor (ET) patients follows that of hand tremor, such that there is a somatotopic spread of involved areas.

Tectonic Model of the 2021 Haiti Earthquake Based on a Newly‐Formed Strike‐Slip Bypass Fault Across a Paired Restraining‐Releasing Bend

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract On 14 August 2021, the southern peninsula of Haiti was struck by an Mw 7.2 earthquake that killed more than 2,200 people. The 2021 epicenter is located 95 km west of the Mw 7.0 2010 Haiti earthquake and 7 km north of the main, geomorphic trace of the EW‐striking, left‐lateral strike‐slip Enriquillo‐Plantain Garden fault zone (EPGFZ) that forms

Investigating volcanic hazard in Cape Verde Islands through geophysical monitoring: network description and first results [PDF]

Natural Hazards and Earth System Sciences, 2014
We describe a new geophysical network deployed in the Cape Verde Archipelago for the assessment and monitoring of volcanic hazards as well as the first results from the network. Across the archipelago, the ages of volcanic activity range from ca.
