We make detailed seafloor maps of offshore geology to identify faults and underwater landslides that may cause tsunamis. We develop computer models of shoreline change and sea-level rise. Powerful storms can destroy critical infrastructure and coral reefs that provide protective coastal barriers. Our science helps vulnerable coastal communities develop strategies to become more resilient.
