Thermal Emissions of Active Craters at Stromboli Volcano: Spatio‐Temporal Insights From 10 Years of Satellite Observations

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.
Abstract Open‐vent volcanoes continuously emit magmatic products and frequently feature multiple adjacent craters. Temporal shifts of thermal emissions between craters are especially detectable by InfraRed satellites. Here, SENTINEL‐2 and LANDSAT‐8/9 Short Wave InfraRed (SWIR) high‐spatial resolution satellite data, are combined to investigate 10 years

Multithreading Based Parallel Processing for Image Geometric Coregistration in SAR Interferometry

Remote Sensing, 2021
Within the framework of multi-temporal Synthetic Aperture Radar (SAR) interferometric processing, image coregistration is a fundamental operation that might be extremely time-consuming.

Large Isotopic Shift in Volcanic Plume CO2 Prior to a Basaltic Paroxysmal Explosion

Geophysical Research Letters, Volume 51, Issue 15, 16 August 2024.
Abstract Carbon dioxide is a key gas to monitor at volcanoes because its concentration and isotopic signature can indicate changes to magma supply and degassing behavior prior to eruptions, yet carbon isotopic fluctuations at volcanic summits are not well constrained.

Clustered and rotating designs as a strategy to obtain precise detection rates in camera trapping studies

Journal of Applied Ecology, Volume 61, Issue 7, Page 1649-1661, July 2024.
Our research provides a guideline for wildlife managers and researchers to improve the precision of camera trap detection rates and optimize resource allocation. In general, the study design should accommodate the behaviour of the target species (e.g.

Three-dimensional simulations of rockfalls in Ischia, Southern Italy, and preliminary susceptibility zonation

Geomatics, Natural Hazards & Risk, 2022
Ischia Island is a volcano-tectonic horst in the Phlegrean Volcanic District, Italy. We investigated rockfalls in Ischia using STONE, a three-dimensional model for simulating trajectories for given detachment locations of blocks.

Towards an automated approach to map flooded areas from Sentinel-2 MSI data and soft integration of water spectral features

International Journal of Applied Earth Observations and Geoinformation, 2020
In this work we propose an approach for mapping flooded areas from Sentinel-2 MSI (Multispectral Instrument) data based on soft fuzzy integration of evidence scores derived from both band combinations (i.e.
