Seismological evidence for subcrustal magmatic injection beneath Fogo volcano, Cape Verde hotspot
, 2019 Fogo volcano belongs to the Cape Verde hotspot and its most recent eruption occurred from November 2014 to February 2015. From January to December 2016 we operated a temporary seismic network on Fogo and were able to locate 289 earthquakes in total. While most of the events occur at distances > 25 km near the neighboring island of Brava. However, on

Geophysical Journal InternationalSUMMARY Continuous seismological observations provide valuable insights to deepen our understanding of geological processes and geohazards. We present a systematic analysis of two months of seismological records using an AI-based Self-Supervised Learning (SSL) approach revealing previously undetected seismic events whose physical causes ...

A Deep Active Learning Approach to the Automatic Classification of Volcano-Seismic Events
Frontiers in Earth Science, 2022 Volcano-seismic event classification represents a fundamental component of volcanic monitoring. Recent advances in techniques for the automatic classification of volcano-seismic events using supervised deep learning models achieve high accuracy. However,

Annals of Geophysics, 2013 In this paper we report seismological evidence regarding the emplacement of the dike that fed the July 18 - August 9, 2001 lateral eruption at Mt. Etna volcano. The shallow intrusion and the opening of the eruptive fracture system, which mostly occurred during July 12, and July 18, were accompanied by one of the most intense seismic swarms of the last ...

Investigating potential icequakes at Llaima volcano, Chile
Volcanica, 2020 Glacially- and magmatically-derived seismic events have been noted to heavily overlap in characteristics, thus there exists the potential for false-alarms or missed warnings at ice-covered volcanoes. Here we present the first study to specifically target

The recent seismicity of Mt. Vesuvius: inference on seismogenic processes
Annals of Geophysics, 2013 We have analyzed the recent seismicity of Mt. Vesuvius, with particular emphasis on the period 1999-2012. Since 1972 continuous observations with electromagnetic seismometers allowed the compilation of a detailed earthquake catalogue for the station OVO.

Geophysical Monograph Series, Page i-xiv., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Crustal structure below Popocat\'epetl Volcano (Mexico) from analysis of Rayleigh waves [PDF]
, 2007 An array of ten broadband stations was installed on the Popocat\'epetl volcano (Mexico) for five months between October 2002 and February 2003. 26 regional and teleseismic earthquakes were selected and filtered in the frequency time domain to extract the

Seismological evidence for Lateral magma intrusion during the July 1978 deflation of the Krafla volcano in NE-Iceland [PDF]
, 1978 The July 1978 deflation of the Krafla volcano in the volcanic rift zone of NE-Iceland was in most respects typical of the many deflation events that have occurred at Krafla since December 1975. Separated by periods of slow inflation, the deflation events are characterized by rapid subsidence in the caldera region, volcanic tremor and extensive rifting ...
