3) The Alps
Language
English
Description
Spanning seven countries, the Alps are the jagged backbone of Europe. How did marine fossils get there, 7,000 feet above sea level? This program attempts to fathom out how the Alps evolved.
4) Coal Gas
Language
English
Description
For decades, scientists have worked to develop technologies that can unlock the energy from coal while reducing the risks of digging it up and burning it. Now entirely new industries are booming as they tap into coal seams either too gassy or too deep to be mined by conventional methods. Watch this video clip to learn about these new methods and what new risks and consequences come along with them.
5) Hawaii
Language
English
Description
This program seeks to understand the beautiful yet violent Hawaiian Islands - a region of explosive volcanoes, vast landslides, mega-tsunamis, and strange forces emerging from the core of the planet.
Language
English
Description
In this program a young environmental engineer takes viewers into the field for an in-depth look at the rock cycle and the geologic processes that occur within Earth's core, mantle, and crust. Using dynamic graphics to illustrate essential terms, the video covers the formation of igneous, sedimentary, and metamorphic rocks; their physical and chemical properties; subgroups and examples of each; and where they fit in to the rock cycle. The video also...
7) Yellowstone
Language
English
Description
Yellowstone National Park houses one of the most dangerous geological features on Earth: a hidden super-volcano. This program examines the volcano's migration hundreds of miles to its present location - a journey of 16.5 million years - and speculates on when that sleeping giant may erupt.
8) Krakatoa
Language
English
Description
This program tells the story of the Indonesian volcano Krakatoa, from its birth approximately 2 million years ago to 1883 - the year it erupted so violently that it blew itself out of existence.
10) Into the Volcano
Language
English
Description
Photographer Carsten Peter is obsessed with devising innovative methods for capturing never-before-seen images from some of the scariest environments on the planet. This program joins Peter as he descends into a hell within paradise, photographing one of nature's most violent forces at work. The Emmy-winning cameraman braves toxic gases, treacherous rock falls, and giant pools of molten lava as he rappels inside the active volcanoes of Vanuatu, an...
11) Tsunami
Language
English
Description
The Sumatra-Andaman earthquake of 2004 is estimated to have released the energy of 23,000 atomic bombs, inundating coastal communities with tsunami waves up to 100 feet high. This program explains the undersea geologic forces that create tsunamis - and considers the possible consequences if a landslide-generated mega-tsunami were to strike the East Coast.

Description
The Earth's surface is a fragile mask, and this Science Screen Report reveals the turmoil beneath it. A cutaway view of the planet depicts its layers-including its crust, hot mantle, and superheated core-and leads to an outline of plate tectonic theory. The Himalayas, the Matterhorn, and the Hawaiian Islands are analyzed as examples of tectonic and volcanic activity, while the core's relationship to Earth's magnetic field is also studied. The program...

English
Description
This Science Screen Report looks at a clean and renewable energy source that is steadily gaining scientific acceptance: hot dry rocks, otherwise known as enhanced geothermal systems. The program shows how masses of heated granite approximately 3 miles underground can be accessed with advanced drilling and computer imaging techniques, and how water forced through fissures in the granite can generate steam to produce electricity. A solid foundation...
14) Vesuvius
Language
English
Description
Mt. Vesuvius - regarded as one of Earth's most dangerous volcanoes - is the most densely populated volcanic region in the world. This program explores the history of Vesuvius and the effects a new eruption could have on nearby Naples.

Description
The 2011 earthquake in Christchurch, New Zealand was devastating for the city's residents and the surrounding landscape. This program presents an in-depth case study of the event, focusing on both the science behind it and its social impact. Using firsthand accounts from seismology experts, emergency response leaders, rebuilding and reconstruction co-coordinators, and local people, the video explains what causes earthquakes, their effects on the environment...

Description
The map of the Earth is a flat picture of the Earth's surface; this BBC Horizon program presents the story of how Harold Wellman changed that picture. Hired by the New Zealand Geological Survey to map the underlying bedrock of the Southern Alps region, he noticed that there were invariably only two kinds of rock, granite and schist. His search for the boundary between the two led to the discovery of the longest straight line on Earth and a radical...

Description
The world is still coming to terms with the magnitude and impact of the tsunami that decimated the coastline around the Indian Ocean on December 26, 2004. This documentary introduces newspaper reporter Ross Coulthart, who traveled across the region soon after the tragedy occurred to record the survivors' stories. He provides a minute-by-minute account of what happened in countries most affected by the disaster. The Day the Wave Came is a comprehensive...
19) Ring of Fire
Language
English
Description
The single longest linear feature in the world, the Ring of Fire encircles almost the entire Pacific Basin. This program investigates how slow but immensely powerful forces of geology in that region shaped - and continue to shape - Planet Earth.
20) Plate tectonics
Language
English
Description
Studies of our planet's crust, or lithosphere, suggest that it's not a single solid layer at all. This video illustrates the process of scientific inquiry by studying the evolution of our understanding of plate tectonics, the dynamics of those ever-shifting slabs of earth we call solid ground. Beginning with Alfred Wegener's hypothesis of continental drift, the program discusses major and minor plates, types of plate boundaries, and the concepts of...
