USGS responses to and studies of the hazards and impact of major hurricanes, tsunamis, and El Nino storms. Includes links to oblique aerial photography and LIDAR surveys recording coastal changes and other effects of storms and waves.
Sedimentary characteristics of 228 tsunami deposits, drawn from published accounts, for interpreting prehistorical, historical, and modern tsunami deposits, and for the development of criteria to identify tsunami deposits in the geologic record.
Fine-grained material may negative effects on coastal ecosystems. Our studies suggest that the waves and currents of California are adequately energetic to transport fine-grained sediment quickly through near-shore coastal systems.
Characteristics of recent tsunami deposits, with the knowledge we have about the events that caused them, give us ways to recognize ancient deposits of this type and infer characteristics of those ancient tsunamis as well.
Research and monitoring to provide the Nation with a clear understanding of natural hazards and their potential threats to society, and assists with developing smart, cost-effective strategies for achieving preparedness and resilience.
With high property damage, loss of life and fire damage were relatively low. Why? The legal system encourages builders to follow code, the electrical grid was shut down early, and emergency response management was very effective.
USGS project to understand coastal evolution and modern beach behavior; to identify and model the physical processes affecting coastal ocean circulation and sediment transport; and to identify sediment sources and construct a regional sediment budget.
Topics in Coastal and Marine Sciences provides background science materials, definitions, and links to give a common context for users from a variety of backgrounds. Coastal erosion was chosen as the first topic.
Homepage for tsunami research with links to information and images on basics, tsunamis in the Pacific Northwest, the 1998 Papua New Guinea tsunami, research on specific tsunamis, and animations in various formats.
