Topic 2c - Part 1: Disaster Risk Resilience - Palu Case Study
On September 28, 2018, a 7.5 magnitude earthquake and tsunami struck Palu, a city of over 330,000 people on the Indonesian island of Sulawesi. The earthquake caused significant soil liquefaction in and around Palu. This resulted in mudslides in two locations, submerging many buildings and killing hundreds of people and leaving many more missing. The economic cost of the disaster, according to government estimates, reached $1.7 billion, owing largely to extensive damage to housing, water supply, irrigation, roads, bridges, airport, and port infrastructure.
ESA and the Asian Development Bank (ADB) have been working closely together, in conjunction with local partners and agencies, to use satellite Earth Observation as a central tool in the reconstruction efforts and to support future planning. The primary goal of disseminating these information products is to assist authorities in better understanding the hazards associated with seismic activity, flooding, and landslides so that they can make more informed decisions when developing a redevelopment master plan.
EO4SD-DRR (Disaster Risk Reduction) consortium member Planetek's automatic cloud-based 'Rheticus Displacement' monitoring service produced ground-motion maps before and after the earthquake. These maps, which are accurate to a few millimetres and based on Copernicus Sentinel-1 radar data, are assisting authorities in determining the impact of the disaster on land surface stability.
In this film, Paolo Manunta, ESA Representative at the Asian Development Bank and Senior Infrastructure Specialist (Earth Observation), outlines this work and explains the importance of on-going training and engagement with local partners.

MOOC topics
In this MOOC, each topic is introduced through a video with supporting text.
We have also provided a range of optional further reading, links, and additional resources to help consolidate your learning. Here is a summary of what is available:
Topic links and resources
In each topic, once you have watched the video and read the accompanying text, you will find the following information:
- Optional Further Reading: These are external links to further reading and other resources.
- Featured Images and Featured Animations: Below the text on Topic video page, you will find the featured images and featured animations that were shown in the Topic video.
- Interactives: On the 'Interactives' tab on relevent topic pages, you will find some interactive data viewers (e.g. ESA's Climate from Space tool), allowing you to explore a selection of data relevant to the themes and topics in this MOOC.
Quizzes
- Quizzes: At the end of each Chapter (and in the middle of Chapter 2) there will be a quiz consisting of around five questions. These will help you consolidate your understanding of new topics, but are not scored. The feedback given with answers will also provide you with important information. These quizzes are informal and therefore there is no formal scoring.
