Most flank eruptions within a central stratovolcano are triggered by lateral draining of magma from its central conduit, and only few eruptions appear to be independent of the central conduit. In order to better highlight the dynamics of flank eruptions in a central stratovolcano, we review the eruptive history of Etna over the last 100 years. In particular, we take into consideration the Mount...

We report the occurrence of several sand liquefaction structures, such as dikes, in stratigraphic record Campi Flegrei volcano, located both inside and outside caldera. Five sites were analyzed within caldera two outside. The grain size analysis fillings indicates that these deposits are very fine-to-coarse sands generally poorly sorted. All granulometry curves fall field liquefiable, loose sed...

The dike-pond system (DPS) is the integration of a natural or man-made pond and crop cultivation on dikes, widely distributed in Pearl River Delta Jianghan plain China. It plays key role preserving biodiversity, enhancing nutrient cycle, increasing production. However, DPS rarely mapped at large scale with satellite data, due to limitations training dataset traditional classification methods. T...
