Even after the smoke clears from a wildfire, the danger is not over. Other hazards such as debris flows (fast-moving, destructive landslides) can also occur in the aftermath of a wildfire. Wildfires and landslides occur in every state and territory; they kill people and cost American taxpayers billions of dollars in disaster aid, disruption of commerce, and destruction of homes.

The U.S. Geological Survey (USGS) National Fish Health Research Laboratory and NOAA´s Cooperative Oxford Laboratory are cosponsoring a workshop on mycobacteriosis in Chesapeake Bay striped bass. This disease, also known as "fish-handlers disease," causes wasting and skin lesions in rockfish, a species that is important to recreational and commercial fishers and the economy of the Chesapeake Bay.

Earthquakes are one of the most costly natural hazards facing the nation, posing risk to 75 million people in 39 states. In an effort to save lives and property, the U.S. Geological Survey (USGS) and its partners are building the Advanced National Seismic System to deliver rapid, robust earthquake information to all U.S. cities with significant seismic risk.
