Interests: The research activity concerns the analysis of the deformative processes that characterize the evolution of volcanic and seismogenic areas, through the development of algorithms for the generation of deformation velocity maps and time series obtained with synthetic aperture radar interferometry (InSAR) techniques and geophysical modeling with analytical and numerical inversions. Recent activity is mainly focused on the development of multi-parametric and multiphysical methodologies for the characterization of stress sources that control the short- and long-term evolution of different geodynamic contexts. The obtained results have been published in peer-reviewed ISI journals.

Special Issue Information

Understanding the behavior and state of volcano systems represents an efficient and robust tool to reduce the associated hazards. The use of data from volcano monitoring represents a scientifically valid basis for short-term forecasts of a future eruption. In recent decades, remote sensing techniques have furnished a fundamental contribution in the growth of knowledge of volcanic systems as well as their structural evolution. Many volcanoes are inaccessible during the climax eruption (or they are located in inaccessible regions of the Earth) and may continue to be inaccessible for a long time also after the eruptive activity. To overcome these limitations, remote sensing is now playing an important role in understanding the science underlying volcanic behavior and is consequently present in any effective hazards-mitigation program.

New research lines are often driven by technological advancements in the development of novel sensors or acquisition platforms. For this reason, processing and complete data fusion of multiparametric, proximal, and remote sensing datasets is crucial for understanding the volcanic processes, increasing the interpretative capacity of the observed volcanic phenomena.

The volume will be favorable to collect studies oriented toward the understanding of several aspects of volcano systems, from the physical characterization of a system to its eruption process, and in proposing adequate multiplatform, multifrequencies, and interdisciplinary data analysis.

In this study, we analyze the 2009–2013 uplift phenomenon at Campi Flegrei (CF) caldera in terms of temporal and spatial variations in the stress/strain field due to the effect of an inflating source. We start by performing a 3D stationary finite element (FE) modeling of X-band COSMO-SkyMed DInSAR and GPS mean velocities to retrieve the geometry and location of the deformation source. The modeling results suggest that the best-fit source is a three-axis oblate spheroid ~3 km deep, which is mostly elongated in the NE–SW direction. Furthermore, we verify the reliability of model results by calculating the total horizontal derivative (THD) of the modeled vertical velocity component; the findings emphasize that the THD maxima overlap with the projection of source boundaries at the surface. Then, we generate a 3D time-dependent FE model, comparing the spatial and temporal distribution of the shear stress and volumetric strain with the seismic swarms beneath the caldera. We found that low values of shear stress are observed corresponding with the shallow hydrothermal system where low-magnitude earthquakes occur, whereas high values of shear stress are found at depths of about 3 km, where high-magnitude earthquakes nucleate. Finally, the volumetric strain analysis highlights that the seismicity occurs mainly at the border between compression and dilatation modeled regions, and some seismic events occur within compression regions.

La Palma is one of the youngest of the Canary Islands, and historically the most active. The recent activity and unrest in the archipelago, the moderate seismicity observed in 2017 and 2018 and the possibility of catastrophic landslides related to the Cumbre Vieja volcano have made it strongly advisable to ensure a realistic knowledge of the background surface deformation on the island. This will then allow any anomalous deformation related to potential volcanic unrest on the island to be detected by monitoring the surface deformation. We describe here the observation results obtained during the 2006–2010 period using geodetic techniques such as Global Navigation Satellite System (GNSS), Advanced Differential Synthetic Aperture Radar Interferometry (A-DInSAR) and microgravimetry. These results show that, although there are no significant associated variations in gravity, there is a clear surface deformation that is spatially and temporally variable. Our results are discussed from the point of view of the unrest and its implications for the definition of an operational geodetic monitoring system for the island. Full article

Title: Anticorrelated Ground Deformation Pattern between Mauna Loa and Kīlauea

Abstract: The contrasting dynamics between Mauna Loa and Kīlauea have been studied over the last 100 years from several points of view. The fact that dynamic changes of one volcano trigger a response of the other volcano seems to indicate that a sort of connection between them may exist. However, petrology studies, discard the existence of a direct connection between the magmatic systems of these two volcanoes. In this work we aim at contributing to this discussion by studying the spatio-temporal relationship between the ground deformation observed at these two volcanoes. For this purpose, we analyzed both DInSAR and GPS data. We used a DInSAR SBAS dataset spanning the 2003–2010time interval and acquired along ascending and descending orbits of the ENVISAT (ESA) satellite under different look angles. From a total of 10 tracks that cover the Big Island (Hawai`i), we selected three of them, covering both volcanic edifices. We considered also the available GPS measurements in the area. Specifically, we computed areal strain time series on 15 triplets of stations for Kīlauea volcano and 11 for Mauna Loa volcano. We applied the Independent Component Analysis (ICA) to the DInSAR SBAS data to identify correlated pattern in the observed ground deformation of both volcanoes. The results revealed an anticorrelated behavior in the ground deformation pattern among the areas of the summit calderas of Mauna Loa and Kīlauea meaning that the opposite respond is seen in the ground deformation behavior of one volcano respect to the other. At the same time Kīlauea shows a more complex pattern, exhibiting an additional component which is not correlated with Mauna Loa. These results are supported by the GPS areal strain time series. To corroborate these findings and to aid the interpretation of the results, we performed an inverse modeling to uncover the parameters of the sources that produce observed ground deformation The results indicate that the anticorrelated sources are both located at shallow depth (about 900 m) beneath the summit calderas. This excludes a direct hydraulic connection as a possible mechanism. Instead we postulate a stress-transfer mechanism to explain the observed anticorrelated behavior. The independent component observed at Kīlauea is located at greater depth (3 km) and shows a more complex spatial pattern. It is likely to be related with the deeper parts of the magmatic reservoir of Kīlauea. Keywords: Volcano Geodesy, Independent Component Analysis, Mauna Loa, Kīlauea, DInSAR, SBAS time series.
