Earthquake Analysis Suggests Dyke Intrusion in 2019 Near Tarawera Volcano, New Zealand

open access: yesFrontiers in Earth Science, 2021
Tarawera volcano (New Zealand) is volumetrically dominated by rhyolitic lavas and pyroclastic deposits, but the most recent event in AD 1886 was a basaltic Plinian fissure eruption.

Monitoring volcanoes in Mexico

open access: yesVolcanica, 2021
Mexico has at least 46 volcanic centers (including monogenetic volcanic fields) that are considered active or potentially active. Due to the federal governance of the country, the Centro Nacional de Prevención de Desastres (CENAPRED) is the entity responsible for monitoring natural hazards. Individual Mexican states also monitor active volcanoes within

UAV survey method to monitor and analyze geological hazards: the case study of the mud volcano of Villaggio Santa Barbara, Caltanissetta (Sicily) [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2021
Active geological processes often generate a ground surface response such as uplift, subsidence and faulting/fracturing. Nowadays remote sensing represents a key tool for the evaluation and monitoring of natural hazards.

Magma recharge and mush rejuvenation drive paroxysmal activity at Stromboli volcano

open access: yesNature Communications, 2022
Petrological studies along with volcano monitoring data relate the unusual 2019 explosive activity at Stromboli volcano (Italy) to deep magma recharges up to a few days prior the eruption and a direct link between deep and shallow magma reservoirs.

Seismological monitoring of the February 2007 effusive eruption of the Stromboli volcano

open access: yesAnnals of Geophysics, 2007
On February 27, 2007, the Stromboli volcano, which has usually been characterized by moderate explosive activity, started an effusive eruption with a small lava flow down the NW flank.

Measurement of small co-seismic deformation field from multi-temporal SAR interferometry: application to the 19 September 2004 Huntoon Valley earthquake

open access: yesGeomatics, Natural Hazards & Risk, 2017
Interferometric synthetic aperture (InSAR) has been widely applied to natural disaster monitoring. However, it has limitations due to the influence of noise sources such as atmospheric and topographic artefacts, data processing errors, etc. In particular,
