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.

Multi-station automatic classification of seismic signatures from the Lascar volcano database [PDF]

Natural Hazards and Earth System Sciences, 2023
This study was aimed to build a multi-station automatic classification system for volcanic seismic signatures such as hybrid, long period, tremor, tectonic, and volcano–tectonic events.

Tectonic tremors immediately after the 2011 Tohoku-Oki earthquake detected by near-trench seafloor seismic observations

Progress in Earth and Planetary Science, 2022
Temporal seismic observations from pop-up type ocean-bottom seismometers were used to detect tectonic tremors immediately following the 2011 Tohoku-Oki earthquake in the northern periphery of the aftershock area.

New detection of tremor triggered in Hokkaido, northern Japan by the 2004 Sumatra–Andaman earthquake

Geophysical Research Letters, 2012
The transient stress change caused by the passage of surface waves resulting from the 26 December 2004 Sumatra–Andaman earthquake triggered seismic tremor in two regions in Hokkaido, in the northernmost part of the Japanese islands, where tectonic tremor

Geohazards in the Western Ionian Sea: Insights from Non-Earthquake Signals Recorded by the NEMO-SN1 Seafloor Observatory [PDF]

Oceanography, 2014
Seafloor instability resulting from both tectonics and volcanism affects the Western Ionian Sea. The NEutrino Mediterranean Observatory-Submarine Network 1 (NEMO-SN1), deployed 25 km offshore eastern Sicily at 2,100 m water depth, records a variety of ...

Tectonic tremor on Vancouver Island, Cascadia, modulated by the body and surface waves of the Mw 8.6 and 8.2, 2012 East Indian Ocean earthquakes

Geophysical Research Letters, 2016
The 2012 East Indian Ocean earthquake (Mw 8.6), so far the largest intraoceanic plate strike‐slip event ever recorded, modulated tectonic tremors in the Cascadia subduction zone.

Automated hypocenter determination of tectonic tremors in the Nankai subduction zone using convolutional neural networks combined with semblance analysis

Earth, Planets and Space
Recent advances in deep learning have enhanced our ability to analyze seismic waveforms. Here, we developed and evaluated a convolutional neural network (CNN) model to classify tectonic tremors, earthquakes, and noise in seismic waveform data recorded by

Citizen Scientists Help Detect and Classify Dynamically Triggered Seismic Activity in Alaska

Frontiers in Earth Science, 2020
In this citizen science project, we ask citizens to listen to relevant sections of seismograms that are converted to audible frequencies. Citizen scientists helped identify local seismic events whose recorded signals are much smaller than those ...

Volcanic and Tectonic Sources of Seismicity Near the Tanaga Volcanic Cluster, Alaska

Geochemistry, Geophysics, Geosystems, 2023
Tanaga Island in the Central Aleutian Islands includes four stratovolcanoes: Sajaka, Tanaga, and East Tanaga in the northwest, and Takawangha in the central part of the island. Of these volcanoes, only Tanaga has a confirmed record of historical eruptive
