“…In terms of studying gas and particle emissions, geostationary observations by the current SEVIRI on MSG, the forthcoming Advanced Baseline Imager onboard GOES-R (2016) and the Flexible Combined Imager onboard MTG (2017), represent a sustainable global capacity of dealing with multiple eruptions at least to 2030. Thanks to greatly improved spectral and spatial resolutions, these meteorological payloads are expected to improve global volcano monitoring (Ferruci et al 2012).…”

“…Recent initiatives such as the Geohazard Supersites and Natural Laboratories (GSNL) initiative (www.earth observations.org/gsnl.php) seek to offer a framework to address some of these challenges. Their strategic aims include: promoting global systematic background observations; increasing systematic observation capability for early warning and alerts; promoting the ability to target any eruption worldwide; improving and/or developing the capability to carry out novel measurements; securing continuity and sustainability of all the above for a 20 year horizon; and improving the uptake of EO through training for end users (Ferruci et al 2012).…”

“…New research is often driven by technological advancements in the development of novel sensors or launching of new platforms, meaning that the space agencies are increasingly involved in identifying scientific questions and priorities (e.g. Ferruci et al 2012).…”

Advanced remote sensing techniques are now capable of delivering more rapidly high quality information that is sufficiently detailed (and cost-effective) for many engineering applications. Here we focus on synthetic aperture radar (SAR), multi-temporal interferometry (MTI). With radar satellites periodically re-visiting the same area, MTI provides information on distance changes between the on-board radar sensor and the targets on the ground (e.g., human-made structures such as buildings, roads and other infrastructure). The detected distance changes are thus interpreted as evidence of ground and/or structure instability. In settings with limited vegetation cover, MTI can deliver very precise (mm resolution), spatially dense information (from hundreds to thousands measurement points/km 2 ) on slow (mm-cm/year) deformations affecting the ground and engineering structures. Radar satellites offer wide-area coverage (thousands km 2 ) and, with the sensors that actively emit electromagnetic radiation and thus can ''see'' through the clouds, one can obtain deformation measurements even under bad weather conditions. We illustrate the potential of high resolution MTI and explain what this technique can deliver to assist in infrastructure instability hazard assessment. This is done by presenting selected examples of MTI applied to monitor post-construction behavior of engineering structures. The examples are from Italy and include: an earthfill dam, an off-shore vertical breakwater built to protect an oil terminal, city buildings and a highway. We also stress that the current approach to the assessment of instability hazard can be transformed by capitalizing more on the presently underexploited advantage of the MTI technique, i.e., the capability to provide regularly spatially dense quantitative information for large areas where engineering infrastructure may currently be unaffected by instability, but where the terrain and infrastructure history (e.g., aging) may indicate potential for future failures.
