PHOTO: The effects of Typhoon Ketsana in the Phillippines, Vietnam and Cambodia

Boston.com - The Big Picture has collected a total of 36 photos showing the effects of Typhoon Ketsana (known in the Phillippines as "Ondoy"), some photos are seen below.

According to the Philippine Atmospheric Geophysical Astronomical Services Administration (PAGASA), Ketsana dropped 455 mm (17.9 in) of rain on Metro Manila in a span of 24 hours on Saturday - the most in 42 years. A month's worth of rainfall in a single day washed away homes and flooded large areas, stranding thousands on rooftops in the city and elsewhere. Ketsana later crossed over to Vietnam and Cambodia, where it is still active. Over 360 people are known to have been killed, and damage estimates are reaching $100 million. Unfortunately, another tropical storm may be headed toward the southern Philippines on Wednesday but is still 1,000 km (600 mi) off the coast. Here is a selection of photographs from the affected areas over the past week.
