Abstract The mild activity of basaltic volcanoes is punctuated by violent explosive eruptions that occur without obvious precursors. Modelling the source processes these sudden blasts challenging. Here, we use two decades ground deformation (tilt) records from Stromboli volcano to shed light, with unprecedented detail, on short-term (minute-scale) conduit drive such volcanic eruptions. We find eruptions, parameters spanning seven orders magnitude, all share a common pre-blast inflation...
After a month-long increase in activity at the summit craters, on 24 December 2018, Etna volcano experienced short-lived lateral effusive event followed by rapid resumption of low-level explosive and degassing vents. By combining space (Moderate Resolution Imaging Spectroradiometer; MODIS SENTINEL-2 images) ground-based geophysical data, we track, near real-time, thermal, seismic infrasonic changes associated with Etna’s during September–December 2018 period. Satellite thermal data reveal...
The ordinarily benign activity of basaltic volcanoes is periodically interrupted by violent paroxysmal explosions ranging in size from Hawaiian to Plinian the most extreme examples. These paroxysms often occur suddenly and with limited or no precursors, leaving their causal mechanisms still incompletely understood. Two such events took place summer 2019 at Stromboli, a volcano otherwise known for its persistent mild open-vent activity, resulting one fatality damage infrastructure. Here, we...
Abstract. While flowing downhill, a snow avalanche radiates seismic waves in the ground and infrasonic atmosphere. Seismic energy is radiated by dense basal layer above ground, while infrasound likely powder front. However, mutual partitioning not fully understood. We present array data of avalanche, which was released on 5 February 2016, Dischma valley Davos, Switzerland. A five-element array, sensitive 0.1 Hz, seven-element 4.5 were deployed at short distance (<500 m) from each other...
Abstract In this paperwe describe a microzonation surveycarried out at mountain Municipality (Piteglio, NorthernApennines). We complemented the available data by conducting106 microtremor measurements for Horizontal-to-Vertical Spectral Ratio (HVSR) analysis. Most of dataconcern three major rural villages (Piteglio-Prataccio,Popiglio and Prunetta). Furthermore, we installed fieldmobile seismic station two villages, in orderto obtain earthquakes recordings.The HVSR analysis shows...
