Back in April 2015 Cyclone Pam hit the Pacific island nation of Vanuatu. It was the most powerful storm yet recorded in the islands, and it was devastating.
But of course people aren't helpless. Patrick Joseph on the island of Efate had trained to prepare his community for disasters like this, 'We put sandbags and stones on the roofs because we weren't sure if the houses would be strong,' he said. After the cyclone Patrick organised a group of young people to rebuild the community meeting house.
