Philippine floods: Stranded using Twitter for help
8 August 2012 Last updated at 07:39 BST
Sixteen people have died in severe floods in the Philippine capital, Manila - nine of them in a landslide which buried their home.
Most of the city is flooded, and almost 80,000 people have taken refuge in emergency shelters.
More than half the amount of rain normally seen in August has fallen in Manila within a 24-hour period.
People who are stranded have adopted the Twitter hashtag #rescueph , and others trying to find them.
Kassy Pajarillo has described how she used the site to help rescue her mother and grandmother.
