Discovery Channel's AMERICA'S TSUNAMI: ARE WE NEXT? Features

Groundbreaking Scientific Information Proving Landslide Did

Not Cause the December 26 Asian Tsunami

- New Scientific Findings Shed Light on Potential Danger for

the West Coast of the United States -

SILVER SPRING, Md., Nov. 16 /PRNewswire/ -- Discovery Channel's
original special, AMERICA'S TSUNAMI: ARE WE NEXT?, premieres in the
U.S. on Sunday, December 18, at 9 PM (ET/PT), reveals new geological
evidence that seafloor uplift from the 9.2 magnitude Great Sumatra
earthquake -- not a giant underwater landslide as previously thought
-- caused the devastating December 26, 2004, Asian tsunami. The
groundbreaking Indian Ocean expedition and new scientific findings
enabled scientists to use data to improve computer- generated tsunami
wave models and better predict the next tsunami wave.

Specifically, scientists point to the northwest region of the United
States (northern California and coastal areas of Oregon and
Washington) as being most at risk for a tsunami event because its
fault lines are a mirror image of those in the Indian Ocean subduction
zone. Scientists estimate that tsunami events happen every 200 to 400
years on the West Coast -- the last occurred on January 26, 1700 --
and with a fault line located just 50 miles off the coast along the
Cascadia Subduction Zone, this region is thought to be the next
target, with potential waves as high as 90 feet.

AMERICA'S TSUNAMI: ARE WE NEXT? follows an international team of 27
scientists led by Dr. Kate Moran from the University of Rhode Island.
The distinguished team quickly mobilized last May and was the first
team to reach the tsunami epicenter. Using state-of-the-art camera
equipment, the special shows never-before-seen footage of the
epicenter and the massive and dramatic geologic changes that caused
gigantic waves.

"We are proud to provide the resources enabling the leading experts to
explore scientific phenomena quickly and accurately while also
immersing viewers in a part of the world they have never seen before.
It is our hope that AMERICA'S TSUNAMI: ARE WE NEXT? helps advance
efforts in gaining a greater understanding of last year's tsunami and
in predicting future destruction," said Jane Root, executive vice
president and general manager, Discovery Channel U.S.

AMERICA'S TSUNAMI: ARE WE NEXT?, funded by Discovery Channel, the BBC
and ProSieben, is a special presentation of Discovery Channel QUEST,
an initiative designed to inspire and fund projects spearheaded by
scientists and explorers who are at the vanguard of their fields.
Their research activities will be chronicled in landmark television
specials that capture the toil, genius, setbacks and exhilaration that
are the lifeblood of the search for knowledge.

Cascadia extends from northern California to the peninsula of British
Columbia and is an exact mirror image geologically to the Indian Ocean
subduction zone where the December 2004 tsunami occurred. Using new
data and improved models from the expedition, scientists predict a
tsunami three times the size of current estimates.

AMERICA'S TSUNAMI: ARE WE NEXT? is an original production produced for
Discovery Channel by Darlow Smithson, broadcast on Discovery Channel
in the U.S., on BBC One in the U.K. and ProSieben in Germany. For
Discovery Channel, Peter Lovering is the executive producer. A version
of this special will air in international markets at a later date.
