BBC: There are growing concerns for the holiday island of Siargao. Its governor said the island was "totally devastated"

Governor of the neighbouring Dinagat islands, Arlene Bag-ao: The fields and boats of our farmers and fisherfolk have been decimated, we have lost our homes. Walls and roofs were torn and blown off…. We have a dwindling supply of food and water. Electricity and telecommunications are down. This is why we urgently and humbly ask for everyone's help.

That sounds grim. Everything you need to live suddenly wiped out. It will be a test for Philippines's disaster response. Hope they're up to it.
