Thermally Activated Static Friction Can Explain Earthquake Interactions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Unlike meteorological hazards, tectonic earthquakes remain hardly predictable, reinforcing their deadly character. This relates to an out‐of‐equilibrium, intermittent dynamic associated with a strong time asymmetry, with few and non‐systematic foreshocks sometimes preceding large earthquakes, while aftershocks are ubiquitous and have been ...

Dynamics of interplate domain in subduction zones: influence of rheological parameters and subducting plate age [PDF]

open access: yes, 2012
The properties of the subduction interplate domain are likely to affect not only the seismogenic potential of the subduction area but also the overall subduction process, as it influences its viability.

Global Primary and Secondary Microseism Multi‐Decade Geographic Variation, Secular Intensification, and Period Lengthening

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earth's long period background seismic wavefield is dominated by two distinct processes that couple ocean wave energy to a global microseism wavefield. We assess global microseism intensity in the secondary (4–10 s) and primary (14–20 s) bands, and across eight 2 s‐wide period bands between 4 and 20 s.

Identification of infrasonic and seismic components of tremors in single-station records: application to the 2013 and 2018 events at Ioto Island, Japan

open access: yesEarth, Planets and Space, 2020
Infrasonic stations are sparse at many volcanoes, especially those on remote islands and those with less frequent eruptions. When only a single infrasound station is available, the seismic–infrasonic cross-correlation method has been used to extract ...

Prolonged Hypocenter Migration in a Lower‐Crustal Earthquake Swarm in Japan: Positive Feedback Between Heat Influx and Fluid Production

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Yamaguchi earthquake swarm in western Japan occurred at unusually deep depths (25–40 km), well below the seismogenic zone, and exhibited prolonged zigzag hypocenter migrations over at least ∼180 days. Seismicity initiated in the southwestern part of the swarm area, followed by systematic migration eastward, northeastward, and northwestward.

Evidence for Stress Diffusion and Along‐Strike Segmentation in Cascadia Tremor Migrations Lasting Minutes to Weeks

open access: yesAGU Advances
The properties and rheology of subduction zones have been intensively studied to forecast potential megathrust earthquake scenarios. However, in Cascadia, the absence of recent megathrust events limits available seismic evidence.

The Marsili Volcanic Seamount (Southern Tyrrhenian Sea): A Potential Offshore Geothermal Resource

open access: yesEnergies, 2014
Italy has a strong geothermal potential for power generation, although, at present, the only two geothermal fields being exploited are Larderello-Travale/Radicondoli and Mt. Amiata in the Tyrrhenian pre-Apennine volcanic district of Southern Tuscany.

On the predictability of volcano-tectonic events by low frequency seismic noise analysis at Teide-Pico Viejo volcanic complex, Canary Islands [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2006
The island of Tenerife (Canary Islands, Spain), is showing possible signs of reawakening after its last basaltic strombolian eruption, dated 1909 at Chinyero. The main concern relates to the central active volcanic complex Teide - Pico Viejo, which poses
