Napa Valley, California
Following the biggest earthquake in 25 years to strike California’s Napa Valley, Sentinel-1a was able to generate an interferogram showing how the ground moved during the quake by processing two images. This capability marks the beginning of a new era in earthquake mapping from space. Source: ESA/PPO.labs/Norut/COMET-SEOM Insarap
