Abstract
Banten is a province on the western point of the island of Java, located north of the active Sunda subduction zone, which has a high level of seismicity. This zone is known as the Sunda Megathrust, which is a large active fault that can trigger shallow earthquakes. Anyer sub-district in Serang district, Banten province, is included in zone G which has the potential to experience an earthquake in the Moment Magnitude range of 3.5 – 7.1 Mw with a 10% probability of earthquake occurrence in 100 years. It is impossible to predict the strength, where, and when of an earthquake. The study was conducted to determine the level of seismic susceptibility to earthquake damage in Anyer sub-district. The seismic vulnerability index in Anyer sub-district ranges from 1.2 to 110.7. The highest seismic vulnerability index values are 110.7 at point M006 and 43.0 at point M007, both in Tanjungmanis village, Anyer sub-district. The areas of Cikoneng and Tanjungmanis villages in Anyar sub-district are zones that are prone to the highest damage in the event of an earthquake.
