Scientists examine evidence of a 50ft tidal wave that surged across the American state of Washington around 12,000 years ago, in a bid to explain where it came from
A giant volcano that lies below the water's surface in a lake in south-east Asia, and the widespread devastation that would be wrought across the planet if it ever erupted
“Earth Shocks: Ring of Fire” investigates the Earth’s rising incidence of volcanic activity. Research indicates that in the last 1,000 years volcanic activity has increased a staggering 300 per cent! One of the most deadly places on Earth, the “Ring of Fire” is a 40,000 kilometre-long chain of volcanoes and earthquake zones that surrounds the Pacific Ocean. “Earthshocks: Ring of Fire” visits this region to investigate the devastating potential that a megathrust of earthquakes would have in this area – and what this means for the two billion people in its wake.
“Earthshocks: Hyper Hurricanes.” Expert testimony from leading scientists combines with stunning computer imaging technology to bring to life vivid depictions of the killer hyper hurricanes that once ravaged the Earth. These vicious storms that annihilated whole ecosystems 3,000 years ago are now poised to make a come back – with a vengeance! “Earthshocks: Hyper Hurricanes” goes into the eye of a hurricane, up to the dizzy heights of the satellites that keep watch on storm activity below, and down to the depths of the Atlantic in Bermuda, exploring the cutting-edge techniques scientists are using to better understand – and predict – hyper-hurricanes.
Volcanoes, Earthquakes, Megafloods, massive tectonic eruptions of rock! Ice dams the size of whole continents, and other bizarre and powerful phenomena have created the American West. In this EarthShocks special we tell as never before the dramatic and surprising story of How the American and Canadian West was made.
For the first time in human history, scientists have found the ultimate fate of Earth written in the comet trail of a massive red giant ‘shooting’ star. As we read this stellar trail, we learn what happens during the end of a star’s life to reveal that when they die, stars can project a killer beam of radiation and particles deadly enough to kill all life that lies in its path. Worse still, there may already be a beam headed this way with our name on it!
65 million years ago an asteroid hit the Earth and wiped out the dinosaurs, but no one has ever known where the asteroid came from and how it killed off nearly three quarters of all life on Earth... Now a group of leading scientists has uncovered alarming new evidence about what really happened, and what might happen if an asteroid collides with us again
