The first image illustrates all the tropical cyclone landfalls in 4 years (00 - 03) to the United States. It's remarkably easy to see how the Gulf states were the "center of attention," sort to speak, over this period of time. The bottom image, the one you are already familiar with, illustrate the landfalls or strikes in the last 2 years. During 2004 and 2005 landfalls occurred over a more wide area and hurricane were extremely intense. Interesting to note, there was no major hurricane landfall from 2000 - 2003, but from 2004 - 2005 there were 7 major landfalls in the US.
