Ten-year helium anomaly prior to the 2014 Mt Ontake eruption
(2015)
Mt Ontake in central Japan suddenly erupted on 27th September 2014, killing 57 people with 6 still missing. It was a hydro-volcanic eruption and new magmatic material was not detected. There were no precursor signals such ...
Seismic monitoring of 2006 Ubinas volcano eruption
(EGU General Assembly, 2007)
At the end of March 2006, Ubinas volcano (16.355º S, 70.903º W, 5672 m) considered the most active volcano of Peru during the last 450 years begun a new eruption process which is lasting until present. The Geophysical ...
Detection of pre-eruptive seismic velocity variations at an andesitic volcano using ambient noise correlation on 3-component stations: Ubinas volcano, Peru, 2014
(Elsevier B.V.NL, 2019-09)
Volcano monitoring and eruption forecasting are based on the observation and joined interpretation of several precursory phenomena. It is thus important to detect new types of precursor and to study their relationship with ...

Seismicity during the recent activity (2009–2020) of Turrialba volcano, Costa Rica
(2022)
Turrialba is a stratovolcano located at the easternmost part of the Costa Rican volcanic front. After remaining quiescent for more than a century, in 1996 it started to show signs of unrest, until a first phreatomagmatic ...
Time-scale wavelet patterns related to the 1998-1999 eruptions of the Colima volcano, and their possible implications for eruption forecasting
(2009)
The seismic activity from one of the most active (documented) periods of the Colima volcano, from October 1998 to July 1999, was analyzed using the wavelet transform, to study the evolution in time of energy content at ...
Are the ashes from the latest eruptions (2010–2016) at Turrialba volcano (Costa Rica) related to phreatic or phreatomagmatic events?
(Elsevier, 2016-09-15)
The initial eruptive episodes of explosive eruptions are classified as phreatic if the amount of juvenile material (scoria, glass, pumice) is null, and the amount of fresh accidental lithics, and hydrothermally altered ...
Crystals reveal magma convection and melt transport in dyke‑fed eruptions
(Nature, 2020)
The processes and ranges of intensive variables that control magma transport and dyke propagation through the crust are poorly understood. Here we show that textural and compositional data of olivine crystals (Mg/Fe, Ni ...
Evolution of eruptive process at Sabancaya Volcano (Perù) 2014- 2018
(Istituto Nazionale di Geofisica e VulcanologiaITA, 2018)
Sabancaya Volcano (5960 m) is a stratovolcano located approximately 80 km southeast of the city of Arequipa in southern Peru. In the Holocene, activity at Sabancaya has included several Plinian eruptions which were followed ...
Short-period volcanic gas precursors to phreatic eruptions: Insights from Poás Volcano, Costa Rica
(Elsevier, 2016-03)
Volcanic eruptions involving interaction with water are amongst the most violent and unpredictable geologic phenomena on Earth. Phreatic eruptions are exceptionally difficult to forecast by traditional geophysical techniques. ...
