“…Different authors [1, 3,6] suggested that the 2014 eruption was triggered by a gradual recharge of the shallow plumbing system and upper conduits. The SO 2 flux in the persistent Stromboli plume has been measured for two months before the onset of the eruption, detecting a strong increase above normal activity in the SO 2 pulses (puffing and explosions) before the effusion onset.…”

The 2014 Effusive Eruption at Stromboli: New Insights from In Situ and Remote-Sensing Measurements

In situ and remote-sensing measurements have been used to characterize the run-up phase and the phenomena that occurred during the August–November 2014 flank eruption at Stromboli. Data comprise videos recorded by the visible and infrared camera network, ground displacement recorded by the permanent-sited Ku-band, Ground-Based Interferometric Synthetic Aperture Radar (GBInSAR) device, seismic signals (band 0.02–10 Hz), and high-resolution Digital Elevation Models (DEMs) reconstructed based on Light Detection and Ranging (LiDAR) data and tri-stereo PLEIADES-1 imagery. This work highlights the importance of considering data from in situ sensors and remote-sensing platforms in monitoring active volcanoes. Comparison of data from live-cams, tremor amplitude, localization of Very-Long-Period (VLP) source and amplitude of explosion quakes, and ground displacements recorded by GBInSAR in the crater terrace provide information about the eruptive activity, nowcasting the shift in eruptive style of explosive to effusive. At the same time, the landslide activity during the run-up and onset phases could be forecasted and tracked using the integration of data from the GBInSAR and the seismic landslide index. Finally, the use of airborne and space-borne DEMs permitted the detection of topographic changes induced by the eruptive activity, allowing for the estimation of a total volume of 3.07 ± 0.37 × 106 m3 of the 2014 lava flow field emplaced on the steep Sciara del Fuoco slope.

“…Stromboli volcano (Italy; Figure 1), a stratovolcano located at the easternmost end of the Aeolian Archipelago, experienced a flank eruption from August-November 2014 [1][2][3][4][5][6][7]. In this paper, in situ and remote-sensing measurements at Stromboli between May and November 2014 are presented.…”

“…The increase in CO 2 concentration in the accumulation chamber at a known volume adhering to the soil is directly proportional to the CO 2 flux [45][46][47]. This method, modified and applied by [48,49], is commonly utilized in the scientific community for geochemical monitoring in volcanic areas [7,9,12,18,19,22,24,25,[50][51][52][53][54][55][56][57][58][59][60].…”

“…The volcanic activity of the Stromboli volcano was monitored over the last 20 years utilizing several geophysical and geochemical techniques. This monitoring activity allowed us to evaluate the level of the Strombolian activity and to individuate the changes between Strombolian and effusive activities [8,9,22,23,52,[61][62][63]. The summit soil CO 2 degassing (Pizzo sopra La Fossa) was monitored using the accumulation chamber method at the continuous STR02 station (Figure 1), a part of the geochemical monitoring network installed on the Stromboli volcano.…”

The last increased volcanic activity of the Stromboli volcano, from 2016 to 2018, was characterized by increases in the number and frequency of crater explosions and by episodes of lava overflow. The volcanic activity was monitored utilizing CO2 soil fluxes acquired from the Stromboli summit area (STR02 station). To better understand the behavior of the shallow plumbing system of the Stromboli volcano in the period of 2016–2018, we utilized a large data set spanning from 2000 to 2018. The data in this last period confirm a long growing trend of CO2 summit degassing, already observed in the years since 2005 (reaching 23,000 g·m−2·d−1). Moreover, within this increasing trend, episodes of sudden and sharp increases in the degassing rate, up to 24.2 g·m−2·d−2 were recorded, which are correlated with the observed paroxysmal activity (increased summit explosions and overflow).
