Organization Title


Almost all of the 50 states (and Puerto Rico) have an agency that deals with geological hazards and resources within its bounds. Some have more than one (e.g., one for petroleum resources, one for general geology, and one for water resources), and some have delegated the responsibilities to a unit within a state university. Most, but not all, of these institutions are connected to the Internet. For all of these agencies, we've included snail mail addresses as well as known e-mail and Internet links.
