Starting in July 2011, anomalous seismicity was observed at El Hierro Island, a young oceanic island volcano. On 12 October the process led to beginning of submarine NW‐SE fissural eruption ~15 km from initial earthquake loci, indicative significant lateral magma migration. Here we conduct multifrequency, multisensor interferometric analysis spaceborne radar images acquired using three different satellite systems (RADARSAT‐2, ENVISAT, and COSMO‐SkyMed (Constellation Small Satellites for...
On Sept. 19th, 2021, the largest historical eruption on island of La Palma began, which had a significant scientific, social, and economic impact. The 2021 Tajogaite was characterised by short precursors, lasting only 8 days. seismicity started 11th with westward upward migration hypocenters. Permanent GNSS stations recording deformation 12th island's western side, reached more than 15 cm just before eruption. After onset, ground increased, reaching maximum 22nd showing nearly steady...
We integrate geologic, structural, leveling and Differential SAR Interferometry data to show that Vesuvius began spread onto its sedimentary substratum about 3,600 years ago. Moreover, we model the detected deformation with a solution of lubrication approximation Navier‐Stokes equations spreading may continue for 7,200 more. Correlation volcanic phases eruptive activity suggests Plinian eruptions, which are thought pose major hazard, less likely occur in near future.

In recent years, a second generation of Synthetic Aperture Radar (SAR) satellite sensor has been designed and, partially, put into operation, leading to an important breakthrough in Earth Science studies. The common characteristics such new systems are, indeed, reduced revisit time (as short as few days) most cases, improved spatial resolution small meters), providing scientists with unprecedented data for the mapping and monitoring natural human-induced hazards. This paper provides overview...

Among Non-Destructive Testing (NDT) methods, Ground Penetrating Radar (GPR) and magnetic surveys are among the most widely used techniques for various applications, including geo-environmental, archaeological, geotechnical, engineering purposes. Their success is attributed to factors such as cost-efficiency, versatility, data collection capabilities. Additionally, both methods enable detection of buried targets through their respective electromagnetic properties. Integrating results from...
Faults are essential structures in the Earth's crust, playing a key role regulating subsurface fluid flow and driving crustal deformation. In volcanic regions, they facilitate migration of magma fluids, significantly influencing processes associated deformation patterns. Understanding interplay between patterns, heterogeneities, fault is critical for accurately interpreting local dynamics, situating them within broader geodynamic frameworks, assessing potential hazards. Boundary analysis...
Between 2004 and 2005, an increased seismic activity exceeding background levels was recorded in Tenerife, the most populated island of Canary Archipelago. Some earthquakes were felt on island, causing concern about a possible eruption among island's population. Ground deformation analysis, conducted using Envisat satellite data from 2003 to 2010 Independent Component Analysis (ICA) statistical tool, revealed several centimetres within Teide-Pico Viejo volcanic complex. This modelled...
