Prince Harry has praised the "extraordinary" volunteers of a humanitarian emergency response organisation as he was spirited to the heart of a devastating earthquake.
Harry spoke of his pride at being patron of MapAction which helps co- ordinate relief efforts in disaster areas as he watched a team responding to a mock earthquake.
The royal looked on intently as a small team of three MapAction volunteers battled to cope with the natural disaster inside a canvas field tent complete with satellite phones, first aid kits and dozens of maps.
MapAction, which is based near High Wycombe, produces maps highlighting not only the geography of an area but where need is greatest and the locations for vital humanitarian aid.
The organisation has successfully deployed to more than 40 emergency missions since its service was launched over 10 years, helping millions of people affected by disaster.
Speaking to potential MapAction donors and existing financial supporters and helpers at the Royal Society in London Harry said he had met volunteers.
He said: "I was struck by their willingness to drop everything at a moment's notice - despite the fact I'd do that in my job anytime - and step into the heart of the crisis no matter where it is in the world, leaving loved ones behind."
He added: "And to do this knowing that very few people will have any idea what contribution they have made. They are extraordinary people and this is an extraordinary organisation."
