Science gateways allow users to access shared data, software and services. GeoGateway (http://geo-gateway.org) is a solid earth geoscience gateway that provides tools for scientific discovery, field use, and disaster response using Interferometric SAR (InSAR) and Global Navigation Satellite System (GNSS) integrated with earthquake faults, seismicity, and model data. GeoGateway was initially developed for researchers to analyze and model crustal deformation related to fault slip and earthquakes. Two highlights of GeoGateway are interactive map displays of global GNSS-based land deformation and thousands of radar images from the NASA airborne platform (UAVSAR). Applications have been expanded to include earthquake nowcasting, and analysis of wildfire burn areas and debris flows for disaster response. We are expanding GeoGateway to include educational applications. To make GeoGateway accessible to a broad audience, we developed a GeoGateway User Guide and example applications. Preliminary exercises and tutorials were tested in the classroom at CalPoly Pomona in 2018, and in workshops at the Seismological Society of America 2019 Meeting, and Geological Society of America 2020 Meeting. We are now developing additional example exercises for use as undergraduate class exercises or problem sets in a variety of geoscience and disaster response classes.
