Detection of deep low-frequency earthquakes in the Nankai subduction zone over 11 years using a matched filter technique

Earth, Planets and Space, 2020
To improve our understanding of the long-term behavior of low-frequency earthquakes (LFEs) along the tremor belt of the Nankai subduction zone, we applied a matched filter technique to continuous seismic data recorded by a dense and highly sensitive ...

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

AGU 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.

Does Episodic Tremor and Slip Influence Seismicity in Northern Cascadia?

Seismica
This paper presents a spatial-temporal analysis of potential links between episodic tremor and slip (ETS) and seismicity in northern Cascadia. We define spatial-temporal clusters of tremor episodes to represent ETS between 2006 and 2024, and we merge ...

Relationship between moment rate of short-term slow slip events and moment rate of tectonic tremors in a frequency range of 1–10 Hz

Earth, Planets and Space
Simultaneous activations of slow slip events (SSEs) and tectonic tremors are observed along subduction zones, and collectively referred to as episodic tremor and slip (ETS).

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

Natural 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

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

Energies, 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.

Tidal correlation of deep tectonic tremors increases during long-term slow slip events in the Bungo Channel, southwest Japan

Earth, Planets and Space
In the Bungo Channel along the Nankai Trough, southwest Japan, long-term slow slip events (LSSEs) of about $${M}_{\text{w}}$$ M w 6–7 and lasting 6–12 months occur at several-year intervals at the base of the seismogenic zone.

Structural control on the shallow tremor distribution linked to seamount subduction: insights from high-resolution seismic imaging in Hyuga-nada

Earth, Planets and Space
Tectonic tremors occur around the subducting seamount of the Kyushu Palau Ridge (KPR) in Hyuga-nada, Japan. We investigate the relationship between tremor activity and structural and physical characteristics using high-resolution reflection seismic ...

Seismic Attenuation Reveals Fault and Forearc Structure Across the Subduction‐Collision Transition in Southern Taiwan

Geophysical Research Letters
The Southern Array for the Lithosphere and Uplift of Taiwan Experiment (SALUTE) provides a new window into the subduction‐collision transition zone in southern Taiwan, where the Eurasian Plate‐Luzon Arc convergence drives intense orogeny and crustal ...
