(Silver Spring, Md.) - Discovery Channel and Science Channel today announced the greenlight of a one-hour television event documenting the dual natural disaster striking Japan earlier this morning. The special, entitled ANATOMY OF A DISASTER, will follow the massive 8.9 magnitude earthquake and resulting tsunami that devastated the east coast of Japan and continues to send its ripple effects as far away as California and Oregon. ANATOMY OF A DISASTER will debut on both networks in early April as a world-premiere simulcast event.

Incorporating unprecedented footage and unparalleled access, ANATOMY OF A DISASTER will provide a full 360-degree view of these historic global events as they unfold across the planet. Beginning with the initial rumblings in the Pacific and capturing the worldwide response effort, Discovery Channel and Science Channel will provide a complete profile of nature's destructive power and mankind's ability to adapt and survive.

"On the strength of our institutional reach and relationships, Discovery Channel and Science Channel will offer a one-of-a-kind look into today's epic natural tragedy," said Clark Bunting, President and General Manager of Discovery Channel. "ANATOMY OF A DISASTER will depict a race against time, from the first wave to hit Sendai, to acts of incredible heroism still yet to occur."
