- A brief account of the Earth's geological progression, from its creation 4.6 billion years ago to scientists' predictions of its demise more than 2.5 billion years in the future.
- What lies beneath the mythical triangle? With the aid of data from sophisticated sonar surveys, National Geographic explores what the ocean floor looks like below the Bermuda Triangle.
- A documentary about the volcanic eruption of Mt. St. Helens in Washington, USA, on May 18, 1980. It was the deadliest volcanic eruption in US history, resulting in 97 deaths and well over $1 billion in damage. Shown are interviews with survivors, scientists, experts on volcanoes and residents of the area. Footage is shown of the mountain before, during and after the eruption, and the resulting destruction to the surrounding forests, rivers and residences and businesses are also shown.
- America's Greatest Animals takes us across North America on a revelatory mission: which of the continent's landmark creatures deserve to make the list?
- Prepare to be awed by the once-in-a-lifetime meeting experienced by a group of divers and photographers in Hawaii, who hung out near a sperm whale carcass to photograph the tiger sharks who came to feed. Suddenly, everything went quiet, and the tiger sharks vanished. A gigantic shadow appeared in the distance. On the program, Dr. Chris Lowe, director of the Shark Lab at California State University at Long Beach, speaks of "dining etiquette" among sharks, which calls for smaller sharks to get out of the way when a bigger shark comes to feed. Sure enough, that shadow proved to be a much bigger shark, and a more famous one than the Hawaiian photographers ever dreamed they'd see in person: Deep Blue. What's more, they would soon learn that Deep Blue may have brought her squad with her. The three great whites encountered and photographed by Kimberly Jeffries, Mark Mohler and Andrew Gray are there for one reason: to chow down at the whale buffet. They express mild curiosity toward their human fans - and one of them does nibble at the boat - but clearly mean them no harm.
- When two couples simultaneously discover a meteor landing site, the claim to the celestial object becomes a battle of wits, gender, and a declaration of love.
- A look at the volcanoes of Hawaii.
- Travel through time, look at the most dramatic eruptions in history and on different continents. Experience a journey deep inside volcanoes. An instructional documentary about how different types of volcanoes are created and where they are or were located, what they have done and what they might do when and if they erupt. The details of the type of volcano one is and the devastation it caused when it did erupt.
- Climate scientists combine data and the observations of Navajo elders to track climate change on the Navajo Nation.
- 2015– 42mTV-PG7.0 (48)TV EpisodeJosh Gates sets sail for Florida chasing the long-lost treasure of bloodthirsty pirate Jose Gaspar. Josh joins marine archaeologists and treasure hunters working to crack the mysteries of the pirate's life so they can find the riches he left behind.
- Instead of looking at a geological feature and the convergence of mechanisms that created it, this program uses a different format; looking at one mechanism, glaciers, and the diverse effects they cause.
- Most major geological processes require millions of year to become noticeable. Meteor impacts are exceptions which can cause comparable changes in seconds.
- The Hawaiian Islands are a study in contradictions. The fastest growing islands on earth are also the fastest disappearing. Made of one of the hardest minerals, it crumbles at a touch. The world's most active volcano is nowhere near the typical volcanic regions. Geologists strive to understand these mysteries.
- The discovery of the San Andreas Fault and efforts to understand it are described.
- Geologists believe the Rocky Mountains recently rose from an inland sea to twice their current size and becoming a new inland sea may be their not to distant fate.
- A tsunami is a dramatic indicator of geological activity magnifying the impact into extensive coastal destruction. Scientists searching for evidence of past tsunamis to predict when they are likely to recur and how severe they are likely to be uncover a new phenomenon, the mega-tsunami.
- Volcanologists look for patterns in the historical eruptions of Mount Vesuvius to determine when the worlds most dangerous volcano is likely to threaten the three million residents of Naples.
- The evidence, structure, history and potential threat of the Yellowstone super volcano are described.
- The dispute between John Muir and Josiah Whitney over how the Yosemite Valley formed is settled with a 200 million year long story more complex then either imagined.
- The causes of the million year volcanic eruption in the Siberian Traps and the resulting effects that lead to the largest mass extinction in earth's history are recounted.
