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

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

The Transition from MODIS to VIIRS for Global Volcano Thermal Monitoring
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
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]
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

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