On 26 December , a massive tsunami devastated Indonesia's coastal city of Banda Aceh, levelling nearly half of the city and killing an estimated , people across the province. Countless others lost their families, homes and everything they owned. In the years that followed, aid providers rebuilt homes on the same plots that had been completely destroyed by the tsunami, in order to avoid displacing the residents. In doing so, they were acting in accordance with a humanitarian principle that comes into play after natural disasters, namely to help survivors to return to their previous places of residence whenever possible. Yet in Banda Aceh, many tsunami survivors preferred to move inland instead, leading to a price premium for properties farther from the coast and socio-economic segregation.
Limitations and challenges of early warning systems: A case study of the 2018 Palu-Donggala Tsunami
Located along the most seismically active zone in the world, Indonesia is no stranger to disasters, in particular, extreme weather events and natural hazards. On 28 September , a tsunami struck Palu and Donggala. As the deadliest disaster in Indonesia and the world last year, its lessons should not be ignored. Indonesia has demonstrated a strong commitment to disaster risk reduction over several decades, including through legislative and regulatory progress, national strategy development, early warning and risk information initiatives. The establishment of institutional and regulatory frameworks for risk reduction at the national and local level was marked by the adoption of Law Number 24 on Disaster Management, which saw the first shift from disaster management to risk management and the creation of National Disaster Management Authority.
Indonesia experiences earthquakes every day, but the scale of the quake and tsunami which hit Palu on Friday took local people and scientists by surprise. As scientists explained to the BBC, a combination of geography, timing and inadequate warnings meant that what happened in Palu was a worst case scenario. Earthquakes are caused by the Earth's tectonic plates sliding against or under each other.
