Haiyan brought sustained winds of 235km/h (147mph), with gusts of 275 km/h (170 mph), with waves as high as 15m (45ft), bringing up to 400mm (15.75 inches) of rain in places. "The world has not seen a storm like this before," said Senen Mangalile, the Philippines Consul General to the UK. Steven Godby, a disaster management expert at Nottingham Trent University, told the BBC the typhoon was "probably the most intense and strongest storm of this type to make landfall".
"We've seen storms like this perhaps on rare occasions that have had that kind of intensity out at sea but for it to come ashore with that kind of strength is almost unprecedented," Dr Godby said. American military aircraft and ships are being deployed to provide help. US President Barack Obama has issued a message saying he was "deeply saddened by the loss of life and extensive damage".
Three days after Typhoon Haiyan hit, aerial photos are revealing a scene of apocalyptic devastation along a swathe of the central Philippines.
