Padang, the capital and largest city in West Sumatra, Indonesia is considesred to have one of the highest tsunami risks in the world due to its high earthquake hazard, vulnerable terrain, and population density (more than 800,000 people). Project partners evaluated Padang’s tsunami evacuation infrastructure and developed a plan with local authorities, the public, and engineers resulting in improved evacuation plans.
The Java Trench seismic gap is one of the largest and potentially deadliest in the world. A mega-thrust earthquake along this trench will potentially expose the most number of people to strong shaking than any other earthquake in history. Recent discoveries of tsunami deposits along the coasts of Java and other island adjacent to the Java Trench document its potential for mega-thrust earthquakes, perhaps as large as the 2004 Banda Aceh event. Following the recent
Many coastal communities in Java, Indonesia, inhabit areas inundated by past tsunamis. This project?s technical approach examined the tsunami risk for coastal communities in Java by examining historical data on tsunamis, sampling tsunami deposits, idesntifying seismic gaps, and creating tsunami models that help better demonstrate the risk to the region. The project used the technical information to create a tsunami preparedness program designed to reduce risk of catastrophic loss in the event of a future
