Volcanoes are complex systems that deserve a multidisciplinary monitoring effort in order to carry out appropriate and timely hazard assessments. In recent years, a number of monitoring techniques based on remotely sensed data have been implemented that enable obtaining synoptic views over the monitored areas. On the other hand, ground-based methods provide punctual, yet more accurate, measurements that complement remotely sensed parameters. It is clear, therefore, that the synergic use of remote sensing techniques and data with ground-based measurements can potentially provide an extra contribution to the hazard assessment, for instance in terms of accuracy of results, amount of information obtained, temporal availability, and so on.
We are seeking contributions that integrate the use of remote sensing and ground-based data, with particular focus on and reference to volcanic processes monitoring and related hazard assessment. In particular, contributions that contain the intersection of and integration between the various terrestrial geophysical monitoring techniques (i.e., seismic, ground deformation), remote sensing both from the ground (i.e., thermal analysis, gas geochemistry) and from satellite (i.e., InSAR, thermal analysis, etc.) are welcome and strongly encouraged. The investigative approach characterized by the integration of disciplines at different scales of vision and precision represent a modern challenge to strive for a more complete understanding of volcanic processes and therefore a better hazard evaluation.

Title: Detailed cartography of Cotopaxi’s 1877 primary lahar deposit obtained by drone-imagery and field surveys in the proximal northern drainage

Abstract: Lahar flows are destructive and potentially lethal phenomena related to volcanic activity, especially in the case of primary lahars which can reach volumes in the order of 106 m3 and discharge rates in the order of 103 m3/s. The assessment of lahar-hazard relies on detailed geological studies of past events and numerical simulations of those flow scenarios. On June 26, 1877 the most recent primary lahar occurred at Cotopaxi volcano as a consequence of an explosive eruption. This event has been widely used as the model scenario to produce hazard assessments for the northern, southern and eastern drainages of the volcano. The geological knowledge of that event, specially the medium- to distal-mapping as well as approximate volumes and discharge rates, has been used to feed several numerical models used to produce lahar-hazard maps for the highly inhabited valleys downstream from the volcano. In order to obtain new insight about the 1877 primary lahar, an enhanced mapping and detailed discharge rate estimations have been obtained in the proximal zones of Cotopaxi’s northern drainage, where the deposits have not yet been eroded or perturbed by human activity. The new mapping has been based on the use of imagery obtained by an un-manned aerial vehicle (drone) which carried visible-light and near infra-red sensors, allowing an enhanced identification of the deposit. The cartography obtained through the drone-imagery was produced by remote sensing techniques enhanced by detailed terrain surveys. The calculation of the discharge rates was based on field measurements preformed in each of the major deep ravines that descend Cotopaxi’s higher flanks to feed the northern drainage. Places where the flow produced super-elevations were used to estimate peak-discharge rates. These field surveys were also improved by the use of the drone-imagery. Thus, a new detailed map of the deposits belonging to the 1877 primary lahars of Cotopaxi has been obtained through this methodology and represent a significant improvement with respect to previous surveys. Given their detail, the results could be now used to test high-resolution numerical models and to improve the lahar-hazard assessment downstream. These new geological data also provides additional insight on the development of the 26 June 1877 eruption of Cotopaxi volcano.
Title: A new analysis of caldera unrest through the integration of ground based geophysics data, InSAR and FEM modeling. The Long Valley caldera case study
Authors: Pulvirenti F.; Silverii F.; Battaglia M.

Abstract: Long Valley Caldera (LVC) is located within the transition between the Eastern California Shear Zone (ECSZ) and the Walker Lane Belt (WLB), at the eastern edge of the Sierra Nevada range (SNR) and represents a highly tectonically active area with long-term shear and extension, frequent episodes of unrest (volcanic inflation) and earthquake swarms. Observed deformations in this area are due to subsurface intrusions as evidenced by seismic, gravity and geodetic data, however, is not clear if the main contribution to the deformations comes from hydrothermal fluxes or magma intrusions. In order to characterize the intrusions, we developed a 3D finite element model where we implemented topography, gravitational load and material heterogeneities and performed numerical joint inversions of gravity, levelling, GPS and EDM data collected during the period 1982 - 1999 to calculate the mass flux, density and volume changes of the intrusions. Results confirm the presence of a modest magma intrusion beneath the caldera resurgent dome.
Title: Using HYSPLIT Model to Improve Volcanic Ash Prediction from Assimilation Satellite Volcanic Top Height and Bottom Height Retrievals

Abstract: HYSPLIT is a Lagrangian transmission and diffusion model, which can be used to predict and study the position, direction and distribution of volcanic ash during volcanic eruptions. The accuracy of HYSPLIT output highly depends on the accuracy of initialization: initial position, size distribution and gray component as a function of time. Cloud thickness is determined by cloud top and cloud bottom retrievals. In this study, a hybrid deep learning method is developed to retrieve volcanic ash top height and bottom height simultaneously through combined polar orbit active and geostationary passive remote sensing data. Using the retrievals from satellite observations with the HYSPLIT model, a new prediction model was developed. A series of eruptions over Iceland’s Eyjafjallajökull volcano from April to May 2010 were selected as typical cases for independent validation of the volcanic height retrievals and the forecast model. The methodology and approaches can be applied to the measurements from the advanced imagers onboard the new generation of international geostationary (GEO) weather satellites for dynamic volcanic ash monitoring and evaluation.
Title: Extensive parameters to monitoring the volcanic activity: The geochemical network of Vulcano Island (Italy)

Abstract: Volatiles degassing from volcanic systems is a peculiar and useful tool to monitoring the volcanic activity to the aims of characterizing the geochemistry of shallow plumbing systems and forecasting and individuating the changes of the volcanic activity level. For this reason, many scientists have carried out investigations on shallow volatile degassing to characterize the normal activity level and for identifying the main active degassing structures that are present on the studied volcanic systems. Consequently, many volcano observatories have been established through the world including geochemical monitoring networks of extensive parameters, like CO2 and SO2 fluxes from soil and plume. Such a geochemical tool has been successful applied to Vulcano Island that is characterized by solfataric activity in the last centuries after the last eruption occurred in the 1888-1890. A geochemical investigation (Inguaggiato et al.2012) was carried out to estimate the CO2 output of discharged fluids from Vulcano Island and individuate the anomalous degassing areas of the Vulcano island. From these studies, we find that the summit area accounts for more than 90 % of total CO2 discharged from the island (Inguaggiato et al. 2012) and is a suitable site for installing geochemical monitoring systems to investigate volcanic activity. Therefore, an automated CO2 soil monitoring station was installed within the active summit crater of La Fossa but beyond the fumarolic areas, in September 2007. Moreover a second anomalous degassing zone was recognize in the Palizzi area located in the NW side of the island were a second monitoring station of soil CO2 has been installed in the 2016. The other extensive parameter useful to monitoring the changes of volcanic activity is the SO2 emitted by the entire solfataric area located on the summit zone (La Fossa crater) of the volcanic edifice. For this reason two UV-Scanning DOAS have been installed in the Palizzi area and Levante beach respectively in the 2008 and 2015. The aim of this article is to present the geochemical monitoring network of extensive parameters installed at Vulcano Island and the obtained results of over 10 years of observations useful to evaluate the degassing activity level.
