Time-resolved seismic tomography detects magma intrusions at Mount Etna.
The continuous volcanic and seismic activity at Mount Etna makes this volcano an important laboratory for seismological and geophysical studies. We used repeated three-dimensional tomography to detect variations in elastic parameters during different volcanic cycles, before and during the October 2002-January 2003 flank eruption. Well-defined anomalous low P- to S-wave velocity ratio volumes we...
متن کاملA statistical analysis of eruptive activity on Mount Etna, Sicily
S U M M A R Y A rigorous analysis of the timing and location of flank eruptions of Mount Etna on Sicily is important for the creation of hazard maps of the densely populated area surrounding the volcano. In this paper, we analyse the temporal, volumetric and spatial data on eruptive activity on Etna. Our analyses are based on the two most recent and robust historical data catalogues of flank er...
متن کاملLava flows impact prediction at Mount Etna by Cellular Automata
Millions of people live either on or in the surrounding areas of about six hundred worldwide volcanoes, which are known to be capable of renewed activity. The individuation of those areas that are more likely to be interested by new events is of fundamental relevance for mitigating possible consequences, both in terms of loss of human lives and material properties. Here we show a new methodolog...
متن کاملMultiple Sclerosis in the Mount Etna Region: Possible Role of Volcanogenic Trace Elements
BACKGROUND Trace elements have been hypothesised to be involved in the pathogenesis of Multiple Sclerosis and volcanic degassing is the major natural sources of trace elements. Both incidence of Multiple Sclerosis in Catania and volcanic activity of Mount Etna have been significantly increased during the last 30 years. Due to prevailing trade winds direction, volcanic gases from Etna summit cra...
متن کاملA Cellular Automata Methodology for Evaluating Lava Flow Hazard at Mount Etna (italy)
Different worldwide volcanic areas are densely populated and urbanized. For instance, in Italy, despite being the most active volcano in Europe, Mt Etna is home to approximately one million people. During the last decades, the vulnerability of the Etnean area has increased exponentially due to continued, at times wild, urbanization, with the consequence that new eruptions may involve even great...
