This week we visit New South Wales, Australia, where the worst bushfires in recent history are attacking multiple towns, overwhelming firefighters and trapping tourists at a lakefront caravan park. The Philippines is usually resilient to natural disasters, but a 6.4-magnitude earthquake catches everyone off-guard — including a family who are trapped in a swimming pool. In England, it's a fight for survival, as a group of cavers attempt to rescue their colleague from the flooded section of an active cave. And in Kansas, two tornado chasers intercept a terrifying twister.
