Abstract The southern sector of Soufrière Hills Volcano failed on 26 December 1997 (Boxing Day), after a year disturbance culminating in devastating eruptive episode. Sector collapse produced c. 50 x 10 6 m 3 volcanic debris avalanche, and depressurized the interior lava dome, which exploded to generate violent pyroclastic density current. south-directed growth lobe build-up lava-block talus, since early November 1997, brought hydrothermally weakened condition marginal stability....

Vulcanian explosions are hazardous and often spontaneous direct observations therefore challenging. Ebeko is an active volcano on Paramushir Island, northern Kuril Islands, showing characteristic Vulcanian-type activity. In 2019, we started a comprehensive survey using combination of field station records repeated unoccupied aircraft system (UAS) surveys to describe the geomorphological features edifice its evolution during ongoing Seismic data revealed activity were complemented by...
Abstract. Karymskoye caldera lake is a nearly circular body of water with diameter approximately 4 km and depth up to 60 m. The sublacustrine, Surtseyan-type eruption in the on 2–3 January 1996 included series underwater explosions. A field survey conducted following summer showed signs tsunami wave runup around entire coastline lake, maximum 29 m at north shore near source eruption, 2–5 locations east south far away from source. has been simulated using numerical long model COULWAVE, input...
Lava domes grow by extrusions and intrusions of viscous magma often initiating from a central volcanic vent, they are frequently defining the source region hazardous explosive eruptions pyroclastic density currents. Thus, close monitoring dome building processes is crucial, but limited to low data resolution, access, poor visibility. Here, we investigated 2016–2017 eruptive sequence Bezymianny volcano, Kamchatka, with spot-mode TerraSAR-X acquisitions, complement analysis webcam imagery...
Abstract Continued post-collapse volcanic activity can cause the rise of a new edifice. However, details such edifice rebirth have not been documented yet. Here, we present 7-decade-long photogrammetric data for Bezymianny volcano, Kamchatka, showing its evolution after 1956 sector collapse. Edifice started with two lava domes originating at distinct vents ~400 m apart. After 2 decades, became more effusive migrating within ~200 distance. 5 focused on single vent to develop stratocone summit...
Abstract U–Th–Ra isotope analyses of whole rocks and mineral separates were conducted in order to perform isochron dating three morphologically young lavas from Tatun volcano, northern Taiwan (from Mt Cising, the Shamao dome Huangzuei volcano). The data do not yield tight U–Th isochrons, indicating open-system magmatic processes. However, crystallization ages two samples can be constrained: namely, less than about 1370 years for dome, based on 226 Ra– 230 Th disequilibrium magnetite,...
