Reducing Tsunami HazardsTo better understand and reduce tsunami hazards, USGS scientists examined sediment deposited by the tsunami in and around Sendai, Japan, as part of an international tsunami survey team organized by Japanese scientific cooperators. Where Are Wildfires Burning?Fire managers and the public can access online maps of current wildfire locations, thanks to a web-based mapping application provided by the USGS and its partners. Investigating the Health of Coastal AlaskaFollow the Pacific Nearshore Project as researchers from the USGS, Monterey Bay Aquarium, and other institutions sail Alaskan waters to study sea otters and investigate coastal health.
