TSUNAMI: IMPACT

Channel 5, 9pm

It will take a hardy viewer to watch this dramatic retelling of the tragic Boxing Day Tsunami of 2004, one of the worst natural disasters in history.

Stripped across three evenings, this is a minute-by-minute analysis of a catastrophe which claimed over 250,000 lives, including 149 Brits.

Xand van Tulleken (pictured) and Raksha Dave follow the progress of the wave, meet experts and speak to those caught up in the devastation.

There is real footage, reconstruction and an experiment in a tsunami simulator. But most compelling are the interviews with survivors, including Luke Simon, whose older brother

Piers died, and Becky Chrosten, who was just 11 and on holiday with her mum and dad when the tsunami struck.
