Spokesperson Ewan Perrin said that number continued to rise as communication was restored to affected areas.
Mr Perrin said, at this stage, there was enough aid in the evacuation centres to go around.
"We've got sufficient essential resources - food, water, medical resources at the moment. We have been very fortunate, the international community has provided a lot of aid and assistance, a lot of materials for us as well.
"So we are able to top those up as we need. We just need to keep an eye on that and see how it goes over the next few days."
