Description of the disaster

Indonesia was hit with several major earthquakes and tsunamis in 2018 with the first major ones striking off Lombok on 29 July 2018 and followed by earthquakes and tsunami in Central Sulawesi on 28 September 2018. Both disasters damaged thousands of buildings and displaced tens of thousands of people.

On 22 December 2018, Indonesia was again hit by a tsunami at Carita Beach in Banten Province and the coast around the Sunda Strait, specifically in Pandeglang, South Lampung and Serang districts. A tsunami early warning was not issued as the cause of the tsunami was not an earthquake, which the current system monitors and responds to. The causes of this event according to the BMKG (Agency for Meteorology, Climatology, and Geophysics), BNPB (Indonesian Disaster Management Authority) and PVMBG (Centre of Volcanology and Geological Disaster Mitigation) was a volcanic tremor from Anak Krakatau mountain which caused underwater landslide and generated the tsunami.

Based on the official statistics from BNPB on 31 January 2018, the tsunami caused 437 death, 14,059 injured and 16 people are still missing. A total of 1,614 houses are severely damaged, 527 houses partially damaged and 97 houses lightly damaged.

BPBD together with the military, police, the national search and rescue agency (Basarnas), local government office, Ministry of Social Welfare Volunteers (Tagana), Indonesian Red Cross (PMI), volunteers and the community provided the initial emergency response to the affected people. The response was coordinated locally from a command post. Heavy equipment is being dispatched to clear debris to ease evacuation and response.

Summary of current response

Overview of Host National Society

Both the Lampung and Banten PMI provincial branches have been actively supporting the affected branches since the onset and have deployed over 649 volunteers from across their provinces. These volunteers had provided support to evacuations, search and rescue, first aid and continue to run medical clinics (mobile and fixed) and referrals, setting up emergency shelter sites, distributing clean water and essential relief items, among other things. To keep their work coordinated and ensure good communications, PMI has established operation command posts (Postco) from which team leaders plan the local response, direct the volunteers, gather information including feedback from the community and offer hot meals to anyone affected or involved in the response. In addition, PMI has recruited and trained 11 Community Based Action Teams (CBAT) as part of the Disaster Risk Reduction (DRR) activities. Each team consists of 20 people from affected communities in both of provinces. In total there are 220 CBAT members actively supporting implementation of activities organized by PMI and external stakeholder in their area, and prepared to respond to any community disaster

With numerous Government agencies and corporate social groups active in the area, PMI only distributed a limited number of NFIs to avoid duplication. PMI provided the NFI based on the gaps in the locations based on assessments from the network of volunteers present in the communities.
