Changes in crater lake chemistry after the 2021 eruption at Aso Volcano, Japan: insights from UAV-based hot water sampling

Journal of Asian Earth Sciences: X
Several volcanoes in Japan have summit craters filled with water, including Zao, Kusatsu-Shirane, Kirishima, and Aso volcanoes. Aso Volcano, located in central Kyushu, is an active caldera volcano with a crater lake whose water volume varies from nearly ...

Evaluation of Pelletized Artificial Geopolymer Aggregate Manufactured From Volcano Ash [PDF]

, 2013
This paper introduced the new pelletized artificial geopolymer aggregate made from volcano ash. This is one of the effort to diminish the high quantity of volcano mud from East Java, Indonesia, that become a major issue since May 29, 2006 when it ...

Seismic characterization of pyroclastic flow activity at Soufrier Hills Volcano, Montserrat, 8 January 2007 [PDF]

, 2007
A partial dome collapse with concurrent pyroclastic flow (PF) activity occurred at Soufrière Hills Volcano (SHV), Montserrat on 8 January 2007. Pyroclastic density currents were observed to propagate from the Northwest and West sectors of the summit dome

Coupled subdaily and multiweek cycles during the lava dome erupt of Soufriere Hills Volcano, Montserrat [PDF]

, 2013
Observations of volcanoes extruding andesitic lava to produce lava domes often reveal cyclic behaviour. At Soufriere Hills Volcano, Montserrat, cycles with sub-daily and multi-week periods have been recognised on many occasions.

The critical role of volcano monitoring in risk reduction [PDF]

, 2008
International audienceData from volcano-monitoring studies constitute the only scientifically valid basis for short-term forecasts of a future eruption, or of possible changes during an ongoing eruption. Thus, in any effective hazards-mitigation program,

Clay minerals in the volcanic ejectas from Kusatsu-Shirane Volcano and the style of eruption.

Journal of the Mineralogical Society of Japan, 1990
Phyllosilicates were present in the volcanic ashes from several 1982-1983 eruptions of Kusatsu-Shirane Volcano . Pyrophyllite, kaolin and smectite were present as major clay minerals. Hydrothermally altered rocks collected from the western flank showed that, the basement rocks of this volcano were altered to form silica minerals, alunite and various ...

Remote surveillance of volcanic unrest at Kusatsu-Shirane volcano, Japan, using a semi-autonomous drone docking station

Uncrewed aerial vehicles (drones) are capable of performing a variety of volcanic measurements quickly and safely. However, most battery-powered drones are limited to flight ranges of only a few kilometers, requiring personnel to be present on-site for ...
