Abstract

On September 28,2018, a 7.5 magnitude earthquakestruckthe
island of Sulawesi, Indonesia. The epicentre was the provincial
capital of Palu, located on a bay on the island's northwest coast. The
quake triggered a tsunami that swept 10-meter tallwavesof seawater
and swamped the city. The combination of the earthquake,
tsunami, soil liquefaction and landslides claimed well over 2000
lives, destroyed homes, buildings, infrastructuresand farmland
in several districts.Recognizing the need to relocate settlements
from the liquefaction-prone areas, the Indonesiangovernment
developed the Master Plan for Recovery and Reconstruction for
Central Sulawesi through the EARR and SWIP projects.
Indra and Planetek Italia contributed to the implementation of
this plan with a batch of EO-based services. The main information
provided was related toterrain deformation mapping (before
the earthquake)followed by the update of terrain information
mapping (in the months immediately after the earthquake)and
reconstruction monitoring with Very High Resolution images.
The collaboration went onwith a capacity-building workshop
and aknowledge transfer activity held in Jakarta in June 2019
regarding the technical aspects of the delivered products andtraining
sessionsfor local users to teach them to use the Geohazards
Exploitation Platform (GEP) of ESA.
