Flank instability at Mt. Etna
Due to their constant and relatively rapid growth, volcanic edifices are inherently unstable. Flank instability is observed at many polygenetic stratovolcanoes, composite volcanoes and shield volcanoes worldwide. Flank instability may occur suddenly, or develop in a more continuous and subtle way, accelerated by triggering events (magma emplacement, eruptions and earthquakes). Destabilization i...
متن کاملSulfur Degassing from Mt. Erebus Volcano, Antarctica
SO2 emission rates from Erebus volcano show periodicity, which directly relates to lava lake convection and magma and conduit processes. Mt. Erebus is a 3794 m stratovolcano with a persistently degassing convecting, phonolite lava lake. Lava lake SO2 emission rates were collected from 1992 to 2003 using the correlation spectrometer (COSPEC) and in 2003 and 2005 using a miniature ultra-violet di...
متن کاملSpatially resolved SO2 flux emissions from Mt Etna
We report on a systematic record of SO2 flux emissions from individual vents of Etna volcano (Sicily), which we obtained using a permanent UV camera network. Observations were carried out in summer 2014, a period encompassing two eruptive episodes of the New South East Crater (NSEC) and a fissure-fed eruption in the upper Valle del Bove. We demonstrate that our vent-resolved SO2 flux time serie...
متن کاملA Probabilistic Approach to Risk Mapping for Mt. Etna
We evaluate susceptibility to lava flows on Mt. Etna based on specially designed die-toss experiments using probabilities for type of activation, time and place culled from the volcano‟s 400-year recorded history and current studies on its known factures and fissures. The types of activations were forecast using a table of probabilities for events, typed by duration and volume of ejecta. Length...
متن کاملMonitoring and forecasting Etna volcanic plumes
In this paper we describe the results of a project ongoing at the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The objective is to develop and implement a system for monitoring and forecasting volcanic plumes of Etna. Monitoring is based at present by multispectral infrared measurements from the Spin Enhanced Visible and Infrared Imager on board the Meteosat Second Generation geosynch...
