What a difference a day makes: When and where are daily satellite observations of morphology and deformation needed during volcanic eruptions and unrest?

June 23, 2026

Daily high-spatial-resolution satellite imagery at active volcanoes could be used to anticipate eruptions and save lives, but is only rarely available or used in real time. Specifically, daily repeat coverage of ground deformation, topography, and surface morphology at volcanoes is now possible using high-spatial resolution optical and radar imagery (
