Multiscale Approach and Integrated Multiplatform Techniques to Study the Volcanic and Geothermal Environments

Geophysical and geochemical data recorded by permanent networks, remote sensing and discrete surveys to monitor active volcanoes and geothermal areas provide a huge amount of valuable scientific data. Recent advances in sensor technology, computing power and modelling algorithms allow for a quantitative joint interpretation of these complex multiparametric datasets. A quantitative interpretation based on a combination of statistical and deterministic approaches seems increasingly achievable. However, it needs integration and exchange of techniques grounded in diverse disciplines across Earth and Environmental Sciences. The final result of this integration is an enhanced and comprehensive understanding of volcanic and geothermal processes, leading to a better forecast of associated hazards.

We aim to display science at the forefront in multiparametric and interdisciplinary surveillance. By assessing the state-of-the-art in multiscale and multiplatform surveillance, we will provide a benchmark for the community working in volcano monitoring and geothermal exploration. The collection will catalyze knowledge transfer to geothermal exploration, focusing on techniques that excel when used with dense surveillance networks. Special attention will be given to the studies that downscale techniques used at the exploration scale to less-dense monitoring networks around geothermal and volcanic systems. A clear focus is on imaging and monitoring with seismological, geodetic, thermal and geochemical approaches using remote and proximal sensing. Furthermore, we consider modelling an essential part of the issue. Analogue and numerical modelling studies of volcanic and geothermal processes are highly sought, especially those that can describe imaging and monitoring parameters obtained from geophysical, geological, and geochemical methods.

This Research Topic collects studies relevant to understanding aspects common to volcanic and geothermal systems, stressing similarities and differences between techniques and instrumentations used to monitor volcanic and geothermal processes. In this context, we expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected. Finally, we stress that the interdisciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies, are also welcome.
