The rains, exacerbated by tropical storms, have led to school and government office closures across the main island of Luzon and flooding in the streets of the capital Manila.
Seven of the deaths occurred in the resort of Baguio, as a rain-drenched mountainside collapsed on three houses, city rescuer Esther Banawe told AFP.
Three people remain unaccounted for."Rescue efforts are continuing, but they are doing it manually because of the heavy rain," she said, adding that work was being supervised by a designated safety officer for fear of further landslides.

State weather forecaster Dan Villamil said rains in the vacation town, four hours north of the capital, were already 47% higher than normal for the whole month.
