Volcanic Tremor and Deformation at Kīlauea
Eos, 2021 Two new studies investigate activity at Hawaii’s Kīlauea leading up to and following the 2018 eruption to better understand the volcano’s plumbing and behavior.

Infrasonic waves and volcanic tremor at Stromboli
Geophysical Research Letters, 1996 The origin of the volcanic tremor is still under debate. Many theories have been proposed in the last years, but none has yet been completely accepted. In 1993, highly sensitive pressure sensors (2.175 Pa/Volt) used to monitor the explosive activity at Stromboli have revealed unexpected correlation between small spike‐shaped pressure signals (1–2 Pa ...

Observations of volcanic earthquakes and tremor at Deception Island - Antarctica
Annals of Geophysics, 1999 Deception Island - South Shetlands, Antarctica is site of active volcanism. Since 1988 field surveys have been carried out with the aim of seismic monitoring, and in 1994 a seismic array was set up near the site of the Spanish summer base in order to ...

Towards a global classification of volcanic tremor
, 2016 Volcanic tremor, a seismic signal with longer durations and lower frequency content compared to local earthquakes, is often observed before or during eruptions and may consequently be useful for eruption forecasting. However, the processes generating volcanic tremor are still poorly understood.

Geosciences, 2019 The NEMO-SN1 seafloor observatory, located 2100 m below sea level and about 40 km from Mt. Etna volcano, normally records a background seismic signal called oceanographic noise.

An Experimental Study of Volcanic Tremor Driven by Magma Wagging
Geophysical Journal International, 2020 Volcanic tremor is a feature of most explosive eruptions. Pre-eruptive tremors can be characterized by monotonic increases in the maximum frequency, frequency bandwidth and amplitude that are correlated with increases in gas flux from a volcanic ...

Helicopter vs. volcanic tremor: Characteristic features of seismic harmonic tremor on volcanoes [PDF]
Journal of Volcanology and Geothermal Research, 2015 We recorded high-frequency (> 10 Hz) harmonic tremor with spectral gliding at Hekla Volcano in Iceland. Particle motion plots indicated a shallow tremor source.

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

Spectral And Fractal Analysis of Volcanic Tremor at Ijen Volcano, Indonesia
IOP Conference Series: Earth and Environment, 2023 A volcanic tremor is one of the seismic events that is usually recorded at the Ijen volcano. In 2014 the status of the Ijen volcano had yet to be declared normal after being critical in 2012. Many volcanic tremors are still recorded since then.
