- Deadliest Earthquakes
- "In 2010, several epic earthquakes delivered one of the worst annual death tolls ever recorded. The deadliest strike, in Haiti, killed more than 200,000 people and reduced homes, hospitals, schools, and the presidential palace to rubble. In exclusive coverage, a NOVA camera crew follows a team of U.S. geologists as they enter Haiti in the immediate aftermath of the tragedy. The team hunts for crucial evidence that will help them determine exactly what happened deep underground and what the risks are of a new killer quake. Barely a month after the Haiti quake, Chile was struck by a quake 100 times more powerful, unleashing a tsunami that put the entire Pacific coast on high alert. In a coastal town devastated by the rushing wave, NOVA follows a team of geologists as they battle aftershocks to measure the displacement caused by the earthquake. Could their work, and the work of geologists at earthquake hot spots around the U.S., one day lead to a breakthrough in predicting quakes before they happen? NOVA investigates compelling new leads in this profound scientific conundrum."

- Japan's Killer Quake
- "In its worst crisis since World War II, Japan faces disaster on an epic scale: a death toll likely in the tens of thousands, massive destruction of homes and businesses, shortages of water and power, and the specter of nuclear meltdown. With exclusive footage, NOVA captures the unfolding human drama and offers a clear-headed investigation of what triggered the earthquake, tsunami, and subsequent nuclear crisis. Can science and technology ever prevent devastation in the face of overwhelmingly powerful forces of nature?"

- Killer Landslides
- "Just before 11 a.m. on March 22, 2014, an ominous rumble startled the residents of the community of Oso, Washington, about an hour's drive from Seattle. It was the terrifying sound of what would become the United States' deadliest landslide in decades. The equivalent of one million dump truck loads of earth came plummeting down the valley. In a little over two minutes, a pile of debris up to 75 feet deep slammed into the neighborhood of close to 50 homes. While a massive search and rescue effort continues at the site, geologists are tracing the geological history of Oso to explain why the site was so unstable. But all around the world, scientists have reason to fear that the worst is yet to come. Globally, landslides and other ground failures take a tremendous human and economic toll, and with climate change bringing a sharp rise in intense precipitation events in many countries, the threat of bigger, more frequent landslides, like one that buried at least 350 people in Afghanistan spring 2014, is growing. In the Himalayas, the threat of devastating landslides is always lurking. As NOVA surveys landslide danger zones, discover how and why landslides happen, and how radar monitoring technologies could help predict landslides and issue life-saving warnings."
