Welcome to Tsunami!

Tsunami! was originally a World-Wide Web site that had been developed to provide general information about tsunamis. Much of the site and its original information is now somewhat out of date, and in fact the site is currently undergoing overhaul. Due to the increased interest following the recent Asian tsunami, we have provided links to off-site information below. We have also put together an image (viewable to the right by clicking on it) that illustrates the basic differences between tsunamis and "regular" wind-generated waves.

The old site and its information can be accessed by following the link near the bottom of the page.
