Typhoon Haiyan, known locally as Yolanda, struck the central Philippines with sustained winds above 300 kilometres per hour and a storm surge that swept several kilometres inland at Tacloban.
More than six thousand people were confirmed killed and around four million were displaced. Airports, ports and hospitals in the affected region were destroyed, delaying relief for days.
The scale of the disaster shaped negotiations at that year's United Nations climate conference, where the Philippine delegate made an emotional appeal for action on emissions and loss and damage.
