Lava 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 کاملNumerical inversion of deformation caused by pressure sources: application to Mount Etna (Italy)
S U M M A R Y The interpretation of geodetic data in volcanic areas is usually based on analytical deformation models. Although numerical finite element (FE) modelling allows realistic features such as topography and crustal heterogeneities to be included, the technique is not computationally convenient for solving inverse problems using classical methods. In this paper, we develop a general to...
متن کاملTime-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 کاملLava flow hazards at Mount Etna: constraints imposed by eruptive history and numerical simulations
Improving lava flow hazard assessment is one of the most important and challenging fields of volcanology, and has an immediate and practical impact on society. Here, we present a methodology for the quantitative assessment of lava flow hazards based on a combination of field data, numerical simulations and probability analyses. With the extensive data available on historic eruptions of Mt. Etna...
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...
