Oxfam has begun distributing bottles of water, biscuits, tents and basic clothing to hundreds of families who have lost everything.
"The conditions are grim. I spent last night in a camp with people who have lost their homes. It started raining in the night and we tried to gather under a few pieces of plastic sheeting to keep dry. While I flew out today the thousands of local people who have lost their homes will have another hard night ahead," added Ms Vilas Boas
Tomorrow Oxfam plans to set up a public kitchen to start providing food to the victims of the earthquake and more staff will be arriving by helicopter to bolster the aid effort.
