Abstract Recent eruptions of the Shinmoedake volcano, Japan, have provided a valuable opportunity to investigate transition between explosive and effusive eruptions. In October 2017, phreatic/phreatomagmatic explosions occurred. They were followed in March 2018 by phase hybrid activity with simultaneous lava flows then intermittent, Vulcanian-style explosions.

A deepened analysis cementitious binding matrix and aggregates was conducted with the aims determining possible sources raw materials mix recipe, to evaluate minerogenetic secondary processes. Twenty samples taken Villa were in...

Pumice rafts are considered to be a long-range drifting agent that promotes material exchange and the dispersal of marine species. Large ones can also interfere with vessel navigation have negative impact on social economy ecosystems. Synoptic observations from Multispectral Instrument (MSI) on-board Sentinel-2, spatial resolution up 10 m, provide an excellent means monitor track pumice rafts. ...
