Evolution of Seismicity During a Stalled Episode of Reawakening at Cayambe Volcano, Ecuador

Frontiers in Earth Science, 2021
Cayambe Volcano is an ice-capped, 5,790 m high, andesitic-dacitic volcanic complex, located on the equator in the Eastern Cordillera of the Ecuadorian Andes.

4D seismic tomography unveiling velocity increase prior to seismic swarms at the Tatun volcano group of Taiwan [PDF]

Scientific Reports
The Tatun Volcano Group (TVG) is in close proximity to the Taipei metropolitan area, which is home to over 7 million residents. Although there has been no recorded volcanic eruption in the TVG throughout human history, recent seismic observations suggest

Earthquake families in the seismicity of Popocatépetl volcano

Geofísica Internacional, 2005
El análisis de la sismicidad asociada al volcán Popocatépetl (Meseta Central, México) en el periodo 1 de septiembre a 31 de diciembre de 1995 permitió la identificación de 3 familias de temblores.

Inflating Shallow Plumbing System of Bezymianny Volcano, Kamchatka, Studied by InSAR and Seismicity Data Prior to the 20 December 2017 Eruption

Frontiers in Earth Science, 2021
Explosive eruptions at steep-sided volcanoes may develop with complex precursor activity occurring in a poorly-understood magma plumbing system so that timelines and possible interactions with the geologic surrounding are often unresolved.

Laboratory Simulation of Volcano Seismicity [PDF]

Science, 2008
The physical processes generating seismicity within volcanic edifices are highly complex and not fully understood. We report results from a laboratory experiment in which basalt from Mount Etna volcano (Italy) was deformed and fractured. The experiment was monitored with an array of transducers around the sample to permit full-waveform capture ...

Seismicity of the Northern Volcanic Zone of Iceland

Frontiers in Earth Science, 2021
A half century of monitoring of the Northern Volcanic Zone of Iceland, a branch of the North America—Eurasia plate boundary, shows that the seismicity is very unevenly distributed, both in time and space.

Envelope Widths of Volcano‐Seismic Events and Seismic Scattering Characteristics Beneath Volcanoes [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractVolcanoes produce highly scattered seismic wavefields, which are characterized by the scattering mean free path (l0) and the quality factor of medium attenuation for S waves (Qi). Previous studies have estimated scattering mean free paths at various volcanoes to be around 100–1,000 m, but their depth distributions remain to be determined.

Automatic Classification of Volcano Seismic Signatures [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractThe prediction of volcanic eruptions and the evaluation of associated risks remain a timely and unresolved issue. This paper presents a method to automatically classify seismic events linked to volcanic activity. As increased seismic activity is an indicator of volcanic unrest, automatic classification of volcano seismic events is of major ...

Use of Local Seismic Network in Analysis of Volcano-Tectonic (VT) Events Preceding the 2017 Agung Volcano Eruption (Bali, Indonesia)

Frontiers in Earth Science, 2021
This study provides an attempt to analyze the pre-eruptive seismicity events for volcano eruption forecasting. After more than 50 years of slumber, Agung volcano on Bali Island erupted explosively, starting on November 21, 2017. The eruption was preceded
