Correlating hydrothermal system dynamics and eruptive activity -- A case-study of Piton de la Fournaise volcano, La R{é}union [PDF]

open access: yesJournal of Volcanology and Geothermal Research, Elsevier, 2018, 363, pp.23 - 39, 2022
Piton de la Fournaise volcano, La R{\'e}union Island, is a basaltic shield volcano which underwent an intense cycle of eruptive activity between 1998 and 2008. Self-potential and other geophysical investigations of the volcano have shown the existence of a well-established hydrothermal system within the summit cone.

Review of the 2022 eruption of Tonga Volcano —Implications for domestic volcano monitoring researches

open access: yes地球与行星物理论评, 2022
On January 15th, 2022, a submarine volcano in Tonga erupted violently and explosively, ejecting a large amount of ash, gas and water vapor which entered the stratosphere to form a huge ash cloud.

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.

Comparison between Automated and Manual Detection of Lava Fountains from Fixed Monitoring Thermal Cameras at Etna Volcano, Italy

open access: yesRemote Sensing, 2022
The Etna volcano is renowned worldwide for its extraordinary lava fountains that rise several kilometers above the vent and feed eruptive columns, then drift hundreds of kilometers away from the source.

The Transition from MODIS to VIIRS for Global Volcano Thermal Monitoring

open access: yesItalian National Conference on Sensors, 2022
The Moderate Resolution Imaging Spectroradiometer (MODIS) is one of the most-used sensors for monitoring volcanoes and has been providing time series of Volcanic Radiative Power (VRP) on a global scale for two decades now.

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.

Response of the underground environment of the KAGRA observatory against the air-pressure disturbance from the Tonga volcano eruption on January 15th, 2022 [PDF]

open access: yesPTEP 2022, 11, 113H02, 2022
On January 15, 2022, at 04:14:45 (UTC), the Hunga Tonga-Funga Ha'apai, a submarine volcano in the Tongan archipelago in the southern Pacific Ocean, erupted and generated global seismic, shock, and electromagnetic waves, which also reached Japan, situated more than 8,000 km away. KAGRA is a gravitational wave telescope located in an underground facility

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,
