Abstract
Mount Merapi in Indonesia has experienced a number of VEI 3 (Volcano Explosivity Index) eruptions in historical times. This animation simulates a 'what if' scenario for a VEI 5 eruption of Mount Merapi using the output results from a volcanic ash hazard model called FALL3D-5.1.1. The simulated eruption occurs over a 12 hour period with a modelled eruption column height of 30 km. The prevailing wind direction is modelled to the southwest towards the nearby city of Yogyakarta (28 km). The animation shows the increase in volcanic ash thickness on the ground over time. The simulation shows that if Mount Merapi erupted under these conditions the city of Yogyakarta could experience ash thicknesses on the ground between 1 and 15 m including thicknesses of 7 - 8 m at the nearby Adisucipto International Airport.
