PDF Fine-grained sediment dispersal along the California coast [More info]
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.
PDF Identification of tsunami deposits in the geologic record; developing criteria using recent tsunami deposits [More info]
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.

Natural Hazards Gateway [More info]
News and related information about the importance of seven major types of natural hazards in the United States: earthquakes, floods, wildfires, hurricanes, landslides, volcanoes, and tsunamis.
PDF Report on the 2010 Chilean earthquake and tsunami response [More info]
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.
PDF South Carolina coastal erosion study [More info]
