Multi-sensor data fusion for remote sensing of post-eruptive deformation and depositional features at Redoubt Volcano

► In this study, we generate elevation change maps of Redoubt Volcano and vicinity, and estimate the Volcano's dome volume. ► We fuse DEMs with InSAR images to demonstrate the positive effect of high-resolution DEMs on deformation measurements. ► Multi-temporal InSAR coherence data was used to plot lahar flows in the Drift River with high accuracy. ► We show that fusion of data from multiple sensors can substantially increase accuracy compared to data from one sensor alone.
