In mid-October 2010, torrential rains flooded parts of Vietnam and China’s southern province of Hainan. The government of Vietnam reported that heavy rains between October 14 and 18 flooded more than 150,000 houses and killed 20 people. CNN reported that heavy rains in Hainan forced the evacuation of some 100,000 residents. Hainan and Vietnam were reeling from torrential rains and flooding even before the arrival of Super Typhoon Megi.
This color-coded image shows rainfall amounts from October 11 to October 17, 2010. The heaviest rainfall—more than 600 millimeters or nearly 24 inches—appears in dark blue. The lightest amounts—less than 75 millimeters or 3 inches—appear in light green. The heaviest rainfall is concentrated over north-central Vietnam and Hainan.
Floods had already struck Hainan Province earlier in the month, CNN reported. Evacuees had taken refuge in government and school buildings. The government of Vietnam, meanwhile, reported that it had mobilized air-, land-, and water-based vehicles for search-and-rescue operations, and had distributed food, life jackets, and medicines.
This image is based on data from the Multisatellite Precipitation Analysis produced at NASA's Goddard Space Flight Center, which estimates rainfall by combining measurements from many satellites and calibrating them using rainfall measurements from the Tropical Rainfall Measuring Mission (TRMM) satellite.
