Multi-hazard Coastal Engineering: Lessons Learned from Indonesia
*NEW. If you missed the talk, you can now find it on our YouTube Channel. Here is the link.
Presentation 1: Short- and long-term effects of the tsunami and co-seismic land subsidence on coastal morphology, structure and vegetation at coastal areas near Banda Aceh (E. Meilianda)
Almost two decades after the 2004 tsunami struck Banda Aceh city of Sumatra, Indonesia, we revisit the affected coastal areas remotely and on-site. We investigate the coastal recovery, the human intervention in responding to the extent of the morphological changes of the coastal area, through the lens of multi-temporal geospatial analysis. We also investigate the recovery and rehabilitation of mangrove ecosystems and the ecosystem's added value for the post-tsunami coastal community. We conducted field interviews with the local inhabitants about their participation in mangrove ecosystem rehabilitation and the role of the mangrove ecosystem for the community.
Presentation 2: Earthquake performance of typical school buildings in Indonesia: Lessons learned from the recent earthquake in Indonesia (Dr. Y. Idris)
Reducing seismic risk for school buildings in Indonesia is of paramount importance. During the very recent recent earthquake in Cianjur, Jawa Barat (21 November 2022), more than 200 schools were damaged. This presentation discusses the damage states for typical school buildings in Indonesia, which have been identified based on an extensive survey data collected on the field in past seismic events.
Presentation 3: An interdisciplinary perspective on community-level recovery projects in Central Sulawesi following the 2018 earthquake, tsunami, and liquefaction (E. Opabola)
The 2018 Central Sulawesi earthquake, tsunami and liquefaction in Indonesia significantly impacted communities in Palu city, Sigi and Donggala regency. Several local and international efforts have gone into the (re)construction and rehabilitation of damaged residential buildings, schools, and hospitals. While some community recovery projects have been successful, several technical and sociocultural factors have impeded recovery in specific projects. This presentation will provide an interdisciplinary perspective on the successes and failures of the recovery process in the disaster-hit communities since the 2018 event.
