Analysis of the Value of Maximum Ground Acceleration in Earthquake Disaster Mitigation Efforts on the Lan

Abstract

The Aceh region itself has a location that is within the scope of the Sumatran fault, areas on active faults can experience a high possibility of earthquakes. Earthquake epicenters on the mainland can occur due to shifts in the Sumatran fault which is indicated by the number of earthquakes along the fault and generally has shallow depths. The research was conducted to determine the value of the earthquake acceleration on the ground around the East Aceh Alue Genteng bridge. The results of this study found that the magnitude of the earthquake can affect the level of acceleration of the earthquake that occurs, the acceleration of the earthquake increases with the magnitude of the earthquake. Based on the results of calculating the acceleration of the earthquake using magnitude 7, 5 SR-9.3 SR, the earthquake acceleration occurred significantly and continues to increase. Earthquake acceleration data is one of the important data that can be used in earthquake mitigation such as in planning strong building structures that are able to withstand loads caused by earthquakes.
