As the world’s largest archipelago, Indonesia is located between the world’s most active seismic region. This situation leads Indonesia to be part of the region that has the highest seismic potential in the world. In recent years, one of the infrastructures that experiences significant development is the toll road. As Indonesia is located in active tectonic areas, it is certainly a challenge in the process of determining the alignment and technical design of the toll road. The original alignment (based on basic design) of Probolinggo-Banyuwangi toll road which is now in the planning stage was passing the Wonorejo fault which is an active fault based on the Seismic Hazard Maps of Indonesia 2017. Because earthquakes are natural events that have not been accurately calculated and estimated, both when and where they occur as well as their magnitude, according to the mitigation strategies for fault rupture suggested by FEMA (Federal Emergency Management Agency), the fault rupture should be avoided, even more, earthquakes have the potential to cause large losses. Based on these considerations, the alignment of the Probolinggo-Banyuwangi toll road is in the process of being submitted for a shift to the east in order to avoid the location of the Wonorejo fault.
