Satellites Support Disaster Response to Storm-Driven Landslides

by R. Emberson, D. B. Kirschbaum, T. Stanley, P. Amatya and S. Khan 9 August 202119 November 2021

Extreme precipitation can trigger deadly landslides. Satellite-based tools provide regional perspectives on landslide hazards, help assess risks in near-real time, and guide emergency responses.
