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.

The acute oral toxicity of the anticoagulant rodenticide diphacinone was found to be about 20 times greater to American kestrels (LD50=97 mg/kg) than to northern bobwhite (LD50=2,014 mg/kg). Several precise and sensitive clotting assays (prothrombin time, Russell's Viper Comparative toxicity of diphacinone to northern bobwhite (Colinus virginianus) and American kestrels (Falco sparverius)
