The science of earthquakes is examined in this episode. Archival footage highlights damage from the great 1906 quake in San Francisco, as well as 1964′s deadly quake in Alaska. Despite efforts to ‘quake-proof’ bulidings, some simply don’t survive; why this happens is explained. Also discussed are tsunamis, caused by undersea earthquakes, and the threat they pose to coasts worldwide. Efforts by scientists to predict earthquakes are also investigated.

On land, in the air, or on the sea–we examine some of the biggest machines ever built, including: the Antonov AN-225, the world’s biggest aircraft; the GE 90-115B jet engine; the Sikorsky CH-53E helicopter; the Union Pacific’s biggest steam locomotive, the “Big Boy” 4000 and GE’s AC 6000; the Discoverer Enterprise, the world’s largest oil-drilling ship; the RB 293 bucket-wheel mine excavator; and the LED Viva Vision, the world’s largest printing screen, which stretches 4-blocks long in Las Vegas
National Geographic Naked Science presents “Super Volcano”, the inside documentary of what might happen if the Yellowstone Caldera were to erupt one day. This documentary includes a Yellowstone timeline of past eruptions, how Yellowstone would affect the world, and what impact will it be for the U.S.
The St. Lawrence Seaway is a monumental stairway in water, lifting massive ships hundreds of feet over thousands of miles. It’s the world’s longest inland waterway, a system of rivers, lakes, canals, dams, and locks that stretches 2,400 miles. And it’s one of the greatest engineering triumphs of the 20th century, pulled off against the violence of raging water and extreme winter. An essential part of the commercial infrastructure of the US and Canada, this complex system provides direct access from the Atlantic to North America’s heartland, enabling ships packed with trade to stop at any one its 65 ports–from Montreal to Duluth. From the 16th century, when French explorer Jacques Cartier searched for the legendary Northwest Passage, to the modern Seaway, built in the 1950s, we highlight the incredible engineering feats that went into creating the waterway.
Sick of being known as “Vince’s guy,” Eric wants a title commensurate with his responsibilities. With his latest shoot taking him to New York for three months, Vince prepares to say goodbye to L.A.–as well as his many “special” girlfriends. Meanwhile, Drama debates taking either a high-paying TV role or a low-paying film gig, and Turtle stakes out a claim as Vince’s “farewell party” promoter.
The Sears Tower, located in Chicago, was finished in 1973. It was the talllest building in the world for over 20 years, and remains the tallest building if you look at highest occupied space. See how the Sears Tower was conceived, designed and built and see how a cigerette pack was the basis for one of Chicago’s most unique buildings.
Hours of never-before-seen footage of Dian Fossey, author of “Gorillas in the Mist”, studying and working with mountain gorillas has been found. It was filmed by Bob Campbell, the wildlife photographer and filmmaker whose footage and photographs propelled Dian and the mountain gorillas into the international spotlight. This documentary tells of the never before mentioned relationship between Fossey and Campbell that turned sour as well as her life that ended in the loss of her friend and her murder.
When opened on October 25, 1931, the George Washington Bridge was the longest suspension bridge in the world. At 3,500 feet in length, the main span was more than double the distance of the previous record holder. Today, standing as a main traffic artery between Manhattan and New Jersey, the bridge referred to by locals as the “GW”, is the busiest in the world carrying nearly 320,000 cars every day. We’ll examine the construction methods employed that made the bridge an anomaly, coming in both under budget and ahead of schedule, and see why the GW is distinguished in a city of great bridges.
