Satellite rainfall estimates from Global Precipitation Mission (GPM) and Tropical Rainfall Measuring Mission (TRMM) revealed extraordinary flooding in Sri Lanka caused by unusually strong monsoonal rainfall over the period 10 September - 30 September 2014.
On 9 - 12 Feb heavy rainfall fell on the island of Java, including the capital Jakarta. Local authorities have reported four casualties and temporary displacement of almost 7,100 people. All IDPs returned to their homes by 13 Feb. Government agencies, Indonesia Red Cross, NGOs, military and police provided search and rescue support and relief to the displaced.
4 people killed
7,100 people evacuated
This map illustrates satellite-detected areas of flood water as observed in Sentinel-1 imagery collected 24 November 2014 and 18 December 2014. Waters extended along coastal areas and shores of inland lakes, with few large bodies of flood waters detected. Numerous roads and railroads are likely inundated by flood waters which may impede transport in those areas. It is likely that flood waters have been systematically underestimated in highly vegetated areas along main river banks, and within built-up urban areas because of the characteristics of the satellite data used.
This map illustrates satellite-detected areas of probable flood waters as detected in a Radarsat-2 satellite image collected 30 December 2014. Detected flood waters are primarily concentrated along coastal areas and shores of inland lakes, with few large bodies of flood waters detected. Numerous roads and railroads are likely inundated by flood waters which may impede transport in those areas.
