Observational Architectures for Enabling Earthquake Forecasting

Abstract Observational architectures for allow-ing the eventual forecasting of earthquakes are dis-cussed. Current science requirements suggest that L-band InSAR systems with short repeat periods would be best suited to such measurements. Con-stellations of such sensors in orbits around 2000– 5000 km altitude might provide optimal Earth coverage for interferometry, while higher orbits around 10,000–40,000 km might approach the goal of around-the-clock coverage for disaster-response applications.
