65 Million Years ago, an asteroid impact caused a cascade of catastrophes that led to the downfall of the dinosaurs, but what would happen if the same size space rock struck near the same spot again?
In the shadow of Italy?s Vesuvius, a lesser-known volcano rumbles: Campi Flegrei. An eruption could endanger the millions of residents of the city of Naples. Scientists gain new insights into what happened in nearby Pompeii, and dig into the unique geology of Campi Flegrei. How will they know if the ever-shifting ground is reaching a breaking point? And can an innovative eruption warning system prevent Naples becoming the next Pompeii?
"Eighty percent of us now live in an urban setting, and I think that the solution to our environmental problems is not to say 'we've got break down cities and get everybody back to the land' – that would be disastrous – but we have to make cities our major habitat…we have to make them more in balance, I think, with the rest of the things that keep us alive." David Suzuki Cities are where most Canadians live. And, as we head into the future, how we adapt to the needs of expanding cities will have a huge impact on their livability. Food, land use, housing, energy, waste – how we tackle these issues will determine whether our cities evolve, or whether they decline. In a new instalment of Suzuki Diaries, David and his daughter, Sarika, set out to discover whether some of Canada's biggest cities are ready for the challenges of the future.
Geologist Prof Iain Stewart shows how the continent of Africa was formed from the wreckage of a long lost supercontinent. He discovers clues in its spectacular landmarks, mineral wealth and iconic wildlife, that help piece together the story of Africa's formation. But he also shows how this deep history has left its mark on the modern day Africa and the world.
Last century, earthquakes killed over one million, and it is predicted that this century might see ten times as many deaths. Yet when an earthquake strikes, it always takes people by surprise. So why hasn't science worked out how to predict when and where the next big quake is going to happen? This is the story of the men and women who chase earthquakes and try to understand this mysterious force of nature. Journeying to China's Sichuan Province, which still lies devastated by the earthquake that struck in May 2008, as well as the notorious San Andreas Fault in California, Horizon asks why science has so far fallen short of answering this fundamental question.
In May 2018, Kilauea volcano erupted, obliterating neighborhoods with devastating force and uprooting thousands of local residents. It is Hawaii's most destructive volcanic eruption in generations. How can one of the most beautiful places on Earth suddenly transform into a roaring inferno, sputtering molten lava and bombs of volcanic rock the size of refrigerators? On the ground in the early days of the eruption, NOVA joins scientists and residents alike on a breathtaking journey to investigate Kilauea's recent spike in activity. Along the way, some of Hawaii's biggest secrets are revealed: Why did these geologically distinctive volcanoes form in the middle of the Pacific? How did life establish itself on the remote islands? What does this tell us about the future of Hawaii? And what dangers yet lurk for the inhabitants of the island paradise?
