The volcano-tectonic map of Etna volcano, 1:100.000 scale : an integrated approach based on a morphotectonic analysis from high-resolution DEM constrained by geologic, active faulting and seismotectonic data

A new volcano-tectonic map of Etna volcano has been compiled through a morphotectonic analysis performed with detailed field mapping, high-resolution DEM and orthoimages, constrained by seismotectonic data. In this study, the AA. present
a homogeneous mapping of the volcano-tectonic and tectonic elements on the whole volcano, consistent with the updated knowledge on the geology and active tectonics observed in historical times. Finally, a seismotectonic model summarises the information regarding

New archeomagnetic and 226Ra-230Th dating of recent lavas for the Geological map of Etna volcano
to reconstruct a coherent sequence of eruptions, and ii) a multidisciplinary approach is necessary to obtain a comprehensive eruptive history of such a very active volcano. Thanks to these new archeomagnetic and 226Ra-230Th data coupled with stratigraphic data

In this paper, the AA. propose a methodology for calculating the size of monogenetic basaltic volcanoes based on morphometric parameters, as well as a classification of the size of the volcanoes through the study of 297 scoria cones of Tenerife
. Morphometric techniques, based mainly on height, volume, and area, were used together with correlations between different morphological parameters. The result is a simple quantitative classification, easy to use for estimating the size of monogenetic volcanoes

Sand volcanoes induced by the April 6th 2009 Mw 6.3 L’Aquila earthquake : a case study from the Fossa area
analyses and datings. The geometrical elements of the sand volcanoes on the surface, of the dike used to rise up and of the probable sandy source at depth are presented. A sandy pockets level found at less than 1 m of depth, interpreted as possible evidence

The goal of the study was to estimate ages of lichen colonization on the oldest moraines of the Ecology and White Eagle Glaciers on King George Island and on the Principal Cone of Penguin Island volcano. The first lichenometric studies
of the oldest moraine ridges are of the Little Ice Age and were colonized at the beginning of the twentieth century. The mid-twentieth century age of lichen colonization on the historically active Penguin Island volcano might support the date of the last

Sunset Crater in north-central Arizona (USA) is a 900-year-old scoria-cone volcano. Wind action has redistributed its widespread tephra deposit into a variety of aeolian dune forms that serve as a terrestrial analog for similar landforms and aeolian
