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, tsunami and liquefaction in Central Sulawesi on 28 September 2018, damaging hundreds of thousands of houses in both areas and displacing hundreds of thousands of people.

On 22 December 2018, another tsunami hit Carita Beach in Banten Province and the coast around the Sunda Strait, specifically in Pandenglang, South Lampung and Serang districts. The tsunami was generated when a part of the Krakatau volcano collapsed into the sea and displacing large quantities of water.

Based on government reports, more than 1,600 houses were severely damaged or destroyed and more than 600 were medium- or lightly damaged, displacing more than 16,000 people. The disaster also killed more than 400 people and injured more than 14,000. More than half of the casualties was recorded in Pandegnlang district.

According to Government reports, the event was recorded four times in four different locations with tidal waves reaching a height of 30-90 cm. The highest wave hit Serang sub-district with a height of 90 cm. BMKG issued high-tide warning before the tsunami struck for the mentioned area. 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.

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 emergency response support to the affected people. The response was locally coordinated in a command post, along with the establishment field kitchens and displacement sites. Heavy equipment was dispatched to clear debris to ease evacuation and response efforts.
