No full textThis paper emphasises the importance of reconstructing the internal architecture of volcanic successions, by defining the hierarchy of the internal unconformities at different scales and the facies associations. Case studies are presented from the ca. 300 Ka, White Trachitic Tuff of Cupa Ignimbrites from Roccamonfina Volcano (Italy), from the 1980 Ignimbrites of Mt St Helens (Washington, USA), and from the 1993 Ignimbrite of Lascar Volcano (Chile)

No full textField observations on the initial lava flow and the fracture system developed during the early days of the Stromboli 2007 eruption
No full textThe February-April 2007 Stromboli eruption was followed by numerous scientists and
well documented from an integrated geophysical analysis. By contrast, direct visual observations
on the summit craters and Bastimento area were difficult during the first three days of the eruption
because of bad weather conditions.
In this paper we report field observations on the fracture system after the crisis of February 27th
and before the summit explosion on March 15th. The observations were focused on the early lava
flow emplacement and deformation at elevations between 400 and 700 m a.s.l., i.e. between the
summit crater area and the lateral fissure eruption, along the Sciara del Fuoco (SdF)
