Global Earthquake Satellite System (GESS)

This report, written by solid-Earth scientists at NASA's Jet Propulsion Laboratory, sets out the requirements for delivering high-accuracy, high-resolution surface deformation data for earthquake studies.

The authors build on recommendations made by NASA's Solid Earth Science Working Group. They propose a constellation of satellites for interferometric synthetic aperture radar (InSAR) — a technique based on combining two or more radar images in a way that can measure ground motion on a centimetre scale.

A constellation of InSAR satellites could provide earthquake prediction data, suggest the authors. The GESS report defines a 20-year roadmap for earthquake forecasting and outlines the measurement requirements, as defined by scientists and disaster managers.
