In the twentieth century, earthquakes have killed hundreds of thousands of people and caused billions of dollars in damage. Seismologists predict the worst is yet to come.

With the help of astonishing footage and interviews, the show reveals the shocking and frightening secrets of this natural killer. You'll discover why New Yorkers and Bostonians should fear earthquakes just as much as Californians, why Tokyo could literally burn to the ground at any time, why Los Angeles could experience another major quake soon, and what will happen if the "Big One" hits.

The San Andreas Fault is a continental transform fault that extends roughly 810 miles through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). The fault divides into three segments, each with different characteristics and a different degree of earthquake risk, the most significant being the southern segment, which passes within about 35 miles of Los Angeles.

A study in 2006 concluded that the San Andreas fault has reached a sufficient stress level for the next "big one", or a M ≥ 7.0, to occur. It also concluded that the risk of a large earthquake may be increasing more rapidly than researchers had previously thought. The paper stated that, while the San Andreas Fault had experienced massive earthquakes in the central (1857) and northern (1906) segments, the southern section of the fault has not seen any similar rupture for at least 300 years. Such an event would result in substantial damage to Palm Springs and other cities in San Bernardino, Riverside and Imperial counties in California, and Mexicali municipality in Baja California. It would be felt throughout much of Southern California, including densely populated areas of San Bernardino, Los Angeles, Orange County, San Diego, Ensenada and Tijuana, Baja California, San Luis Rio Colorado in Sonora and Yuma, Arizona.

As both the public and scientific community continue to speculate on the size of the next earthquake to strike California, predicting major earthquakes with sufficient precision to warrant taking increased precautions has long been sought but remains elusive.[10] Nonetheless, the 2008 Uniform California Earthquake Rupture Forecast (UCERF) has estimated that the probability of an M ≥ 6.7 earthquake within the next 30 years on the northern and southern segments of the San Andreas fault is somewhere between 21% and 59%, respectively.

This is a documentary about the tidal wave which hit off the coast of Indonesia a day or two after Christmas in 2004. This is caused by the 8.8 magnitude earthquake that hit Sumatra–Andaman. This tsunami was given various names, including the 2004 Indian Ocean tsunami, South Asian tsunami, Indonesian tsunami, the Christmas tsunami and the Boxing Day tsunami.

The Tsunami of December 26 2004 took the lives of at least 250,000 people across more than a dozen countries. It is also energized science to seek a better understanding of this killer waves. The goal to figure out exactly what happened and what wen wrong. Three months after the Tsunami, what have we learned about this catastrophe? Why did it occur and will we be better prepared the next time.

It was early morning on December 26, 2004. Southeast Asia awakes to what should be another ordinary day. Fisherman were on the water in Sumatra. In Sri Lanka 1500 people took a train a long the coast. In Thailand Tom Travers and Richard Anthony opened their beach front restaurant. And In Hawaii, scientist at the Pacific Tsunami Warning Center carried out routine tests of their equipments. All of these people were unaware that they were about to be caught up in one of the worst natural disasters ever.

It began shortly after dawn and without warning when a huge earthquake tears a part the floor of the Indian Ocean. The earth's crust in divided into giant wrapped of rock called Tectonic plates. The plates are always on the move. When they collide, enormous amounts have train buildup where the plate grind past each other earthquakes occur.
