Dangerous Earth


Series 1 - Episode 1 Avalanche



Our planet is a tricky place: sometimes I’m amazed that we humans have managed to survive the range of natural obstacles stacked against us. In this new series, Dr Helen Czerski looks at some of Earth’s great dangers, and how new technology is revealing fresh insights into eye-opening natural phenomena.

First off: avalanches. If you’ve ever seen one in action – either on screen or from a safe distance on holiday – you’ll know how terrifying they can be. But what actually causes them? And can anything be done to minimise their danger? CT scans, radar and computer modelling are providing invaluable information, but petrifying eye-witness footage confirms why I’ve never booked a skiing trip…


Dr Helen Czerski presents this documentary showing how new camera technology is revealing the inner workings of the Earth's most spectacular natural wonders. The first programme looks at the anatomy of an avalanche, from eyewitness footage from within one to detailed CT scans showing the microscopic changes that cause them.
