Crisis Impact Overview
• Between 31 December 2019 and 1 January 2020, the Northeast monsoon brought rainfall to Indonesia, leading to heavy flooding across the Greater Jakarta area including parts of West Java, Banten, and DKI Jakarta provinces. 74 districts and 293 sub-districts in the provinces were hit by flooding and the mayors of 12 affected cities and regencies declared emergency status. (ECHO 08/01/2020) (AHA 06/01/2020) (AHA 07/01/2020)
• January 1 rainfall averaged 50mm a day. Landslides were reported in Banten and West Java provinces and high tides reportedly detained water inland over the first week of January, exacerbating flooding. As of 8 January, flooding had reportedly receded in Jakarta, West Java, and Banten but mud and debris still posed a hazard and could limit access. (ECHO 08/01/2020) (AHA 06/01/2020) (AHA 07/01/2020)
• 67 people were reportedly killed in the flooding period; one person is still missing. West Java bore the heaviest casualties and the highest number of displaced people. (ECHO 08/01/2020) (AHA 07/01/2020)
• 14,000 people were reportedly displaced on the 8 January, down from previous days' estimates. The figure as of 10 January has gone up to 28,000, particularly related to displacement in Bogor Regency,
West Java. The displaced are spread across 60 emergency shelters. (ECHO 10/01/2020)
• 1,600 houses across the three provinces were damaged by the flooding and many homes were submerged. Villages in Banten province were destroyed. Some settlements near rivers are inundated or covered in mud and/or debris (AP 05/01/2019) (AHA 07/01/2020).
Anticipated scope and scale
• Heavy rainfall is forecast to continue across Indonesia over the next 48 hours as of January 10, notably in the Greater Jakarta area but also in the middle Sumatra, Java, South Kalimantan, and South Sulawesi areas.
- Indonesia’s rainy season is projected to last until February, which may • pose further challenges to response and reconstruction efforts.
• Flooding caused power outages, road closures, damage to a bridge in Banten, and impaired telecommunications which may restrict response efforts. (ECHO 08/01/2020) (Time 08/01/2020)
• Although water has receded in most areas, responses are ongoing. Over the last week there have been reports of isolated villages affected by the floods that were only accessible by helicopter. (ECHO 08/01/2020) (AP 05/01/2019)
