Rapid tremor migration and pore-pressure waves in subduction zones [PDF]

Nature Communications, 2018
Rapid tremor migration in subduction zones has been associated with aseismic, shear strain at the plate interface. Here, the authors develop a physical model that shows that pore-pressure waves at the plate interface are likely to generate secondary slip

Migration of Deep Low-Frequency Tremor Triggered by Teleseismic Earthquakes in the Southwest Japan Subduction Zone

Geophysical Research Letters, 2018
Deep low‐frequency tremor triggered by teleseismic surface waves is concentrated in several locations along the ambient tremor source region in the Nankai subduction zone, southwest Japan.

Depth Migration of Seismovolcanic Tremor Sources Below the Klyuchevskoy Volcanic Group (Kamchatka) Determined From a Network-Based Analysis

Geophysical Research Letters, 2019
We present a method for automatic location of dominant sources of seismovolcanic tremor in 3‐D, based on the spatial coherence of the continuously recorded wavefield at a seismic network.

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.

Seismic detection of mofette activity with matched field processing: method validation and field results in the western Eger Rift (Czechia) [PDF]

Scientific Reports
Deep-derived carbon dioxide (CO2) degassing is a globally important process linking crust–mantle fluid transport with atmospheric carbon budgets. Matched Field Processing-Bartlett Beamformer (MFP-BB) method offers a seismic approach for detecting tremor ...

Characterizing and Locating Seismic Tremor during the 2022 Eruption of Mauna Loa Volcano, Hawai’i, with Network Covariance

The Seismic Record, 2023
The 2022 eruption of Mauna Loa Volcano, Hawai’i, was accompanied by continuous seismic tremor that began about 30 min before and ended several days after the eruption.

Spatiotemporal evolution of tremor activity near the Nankai Trough trench axis inferred from the spatial distribution of seismic amplitudes

Earth, Planets and Space, 2022
Slow earthquakes have gained importance due to their proximity to the focal regions of megathrust earthquakes. Among slow earthquakes, tectonic tremors have the highest dominant frequency and are thus best resolved.

Forecasting tectonic tremor activity using a renewal process model

Progress in Earth and Planetary Science, 2022
In many tectonically active regions of the world, a variety of slow deformation phenomena have been discovered and collectively termed slow earthquakes.

Harmonic tremor from the deep part of Hakone volcano

Earth, Planets and Space, 2022
The feeding system of magmatic fluid from the volcanic root to a shallow magma reservoir remains a poorly understood issue. Seismic events, including volcanic tremors and low-frequency earthquakes, in a deep part beneath volcanos are key observations for

Locating hydrothermal fluid injection of the 2018 phreatic eruption at Kusatsu-Shirane volcano with volcanic tremor amplitude

Earth, Planets and Space, 2021
Kusatsu-Shirane volcano hosts numerous thermal springs, fumaroles, and the crater lake of Yugama. Hence, it has been a particular study field for hydrothermal systems and phreatic eruptions.
