Regional and global variations in the temporal clustering of tectonic tremor activity [PDF]

Earth, Planets and Space, 2014
The temporal distribution of tremor activity exhibits a highly non-Poissonian behavior, and its maximum period of non-Poissonian clustering statistically describes the recurrence interval of major tremor bursts. Here, we examine variations in the temporal clustering properties of tremor activity by assessing their characteristic times, which are ...

Environmental pollution and sustainable restoration of the Yamuna River: A review of water quality, health risks, and phycoremediation

River, Volume 5, Issue 3, Page 398-418, August 2026.
Abstract The Yamuna River, one of India's most significant river systems and the largest tributary of the Ganges River, serves critical ecological, socio‐economic, and cultural functions. However, rapid urbanization, industrialization, and intensive agriculture have severely degraded its water quality, resulting in extensive pollution with untreated ...

Pre‐Eruptive Volatiles and Magma Storage Depth for the 2018 Eruption at Mount Veniaminof, Alaska

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Mount Veniaminof is a frequently active, open‐system arc volcano on the Alaska Peninsula, part of the Alaska‐Aleutian arc. Mount Veniaminof's September–December 2018 eruption began with small lava flows and culminated in a larger explosive event in November that produced a 450 km long continuous ash plume—one of the volcano's most significant ...

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.

The role of velocity‐neutral creep on the modulation of tectonic tremor activity by periodic loading [PDF]

Geophysical Research Letters, 2012
Slow slip events and associated non‐volcanic tremors are sensitive to oscillatory stress perturbations, such as those induced by tides or seismic surface waves. Slow slip events and tremors are thought to occur near the seismic‐aseismic transition regions of active faults, where the differencea − b = ∂μ/∂lnVbetween the sensitivity of friction to slip ...

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.

Harmaline Tremor: Underlying Mechanisms in a Potential Animal Model of Essential Tremor [PDF]

, 2012
Background: Harmaline and harmine are tremorigenic β-carbolines that, on administration to experimental animals, induce an acute postural and kinetic tremor of axial and truncal musculature.

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes

Geophysical Research Letters
Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress ...

Probing Slow Earthquakes With Deep Learning

Geophysical Research Letters, 2020
Slow earthquakes may trigger failure on neighboring locked faults that are stressed sufficiently to break, and slow slip patterns may evolve before a nearby great earthquake.

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.
