Abstract

Some of the damage caused by earthquakes is not always caused by the strength of the earthquake or the distance from the epicenter of the earthquake to the affected buildings but is also influenced by local geological conditions. Majangtengah Village, Dampit District, Malang Regency is one of the areas that experienced considerable damage due to the earthquake in southern East Java on April 10, 2021. One of the geophysical surveys used to determine the potential for local site effect hazards is the microtremor survey. This study aims to determine the level of soil vulnerability based on the value of dominant frequency (f0), amplification (A0), and seismic vulnerability index (Kg) using HVSR analysis. Microtremor data measurements include 9 points with a recording duration of 45 min. The results of microtremor data analysis obtained dominant frequency values (f0) between 2.42–4.33 Hz, amplification values (A0) between 2.78–8.19, and seismic vulnerability index values (Kg) between 3.19–20.11 cm/s2. This condition illustrates that the research area is unstable because it has a high vulnerability index value.
