DEADLY WAVES pounded the shores of Sri Lanka, claiming the lives of thousands.

It is the worst natural disaster in decades. On December 26 a gargantuan undersea earthquake off the coast of Sumatra rocked the Indian Ocean, sending killer waves racing toward land. Ravaging shores from Indonesia to Somalia, the tsunami claimed the lives of an estimated 150,000 people and left millions of others homeless and vulnerable to starvation and disease. In the hopes that Scientific American's past coverage may help readers to understand why earthquakes and tsunamis occur--and the efforts scientists are making to predict them--we have pulled together a collection of our articles on these subjects. Links to other sites on the Web documenting the tragedy, as well as a list of some of the organizations accepting donations to aid its victims, follow.
