Chicago: The photo depicts a crowd of new boats pulled up to shore, their brilliant blue and red paint jobs shiny in the sun.

But on land, last year's tsunami's devastation is still evident a coastline devoid of trees, a shack in the background that is falling apart.

"It's in some ways very hopeful, but even a year afterward, it really shows that there's more to be done," said Mike Sarna, director of exhibits at The Notebaert Nature Museum in Chicago.

The photograph is part of a new exhibit at the museum, called "Tsunami: Science and Hope," that centres around the earthquake-spawned tidal waves on December 26, 2004, that left at least 216,000 people dead or missing in 12 Indian Ocean nations.

The exhibit consists of 20 photos that examine the scientific underpinnings of this particular tsunami and others in history.

A map shows the locations of the few tsunami warning systems that currently exist, mostly off the coast of the northwestern US, and where officials hope to place more than a dozen more.

Despite its limited scope, the exhibit is unique in that it resulted from a relationship the museum has developed with Heifer International, a group that seeks to combat poverty and world hunger by providing families in dozens of countries with animals they can use to support themselves.
