“…The secondary data are collected from GIS maps, satellite images, administrative data, ground motion, and seismic data. The demand spectrum is generated from Laurendeau et al [8] attenuation function [7] by using three hypothetical earthquake scenarios (6, 6.5, 7 Magnitudes). The yield and ultimate capacity values of building types are published in the HAZUS manual book.…”

Indonesia is not only known as an archipelago that is rich innatural resources but also known as a disaster-prone country. Because ofits location in four major Eurasian, Indo-Australian, Pacific, and Philippinetectonic plates, natural disasters such as earthquakes, floods, landslides, volcanic eruptions, droughts, forest fires, and tsunamis often occurthroughout the region. In 2006, a large earthquake shocked the denselypopulated Yogyakarta Province and its surrounding areas. This earthquakecaused huge fatalities and damaged thousands of buildings andinfrastructures. The Pacitan region is geographically close to Yogyakarta, and is located only 120 km from the epicenter of the quake. Therefore, awareness of disaster mitigation is a critical action in reducing disasterrisks. In addition, the Pacitan Regency is a hilly and mountainous regioncovering a total area of 1,389.87 km. Its territory also includes karstregions and lowland areas. A preliminary research utilizing the HAZUSmethod was conducted for assessing the damage probability of residentialhouses at an earthquake-prone area of Pacitan sub-district. The indicativeresults show that the unreinforced masonry (URML) types are the mostdestructive followed by Wood, light frame (W1), reinforced masonry lowrise(RM2L), and reinforced masonry mid-rise (RM2M) when appliedacross three scenarios of earthquake with magnitudes of 6, 6.5, and 7, respectively.

“…Both the Martins and Silva (2020) and the Villar-Vega et al ( 2017) functions are analytically derived functions, and for the types of buildings in Indonesia the functions are quite similar. In addition, the widely used HAZUS (FEMA 2020) functions were selected as they have been used in previous studies in Indonesia (Pratiwi et al 2019). The HAZUS functions are derived through a combination of analytical methods, expert opinion, and empirical data.…”

Indonesia is located in one of the most seismically active regions in the world and often experiences damaging earthquakes. In the past the housing sector has sustained higher earthquake related damage and losses than other sectors. This is often attributed to the fact that the most common houses in Indonesia are non-engineered, built with poor quality workmanship, poor quality materials and without resilient seismic design features. However little effort has been made to quantify how fragile Indonesian houses are, or how their fragility may vary according to the population density or relative wealth of a region. It is not possible to derive empirical fragility functions for Indonesia due to insufficient damage data. The aim of this study is to determine whether existing earthquake fragility functions can be applied to common house types in Indonesia. Scenario damage analyses simulating the 2006 Yogyakarta and 2009 Padang events were undertaken several times testing different fragility functions. The simulated damage results were then compared to the damage observed post event to determine whether an accurate damage prediction could be achieved. It was found that the common house types in Yogyakarta and Central Java vary according to age of construction, location and relative wealth of a region and can be reasonably well represented by existing fragility functions. However, the houses in Padang and surrounding West Sumatra did not vary in a predictable manner and are more fragile than anticipated. Therefore, the fragility of the most common house types in Indonesia differs between Central Java and West Sumatra. This has important implications for seismic damage and risk assessment undertaken in Indonesia.

On April 18, 2018, an earthquake hit Banjarnegara Regency, Central Java. The earthquake was measured M4.4 at a depth of 4 km and caused damages to buildings in several villages within Kalibening District. Predicting the future earthquake events is difficult. However, it is possible to estimate the potential damage caused by an earthquake event. FEMA has developed a methodology called HAZUS to estimate the potential loss and damage caused by earthquakes. This study compared the level of actual damage to buildings subjected to the 2018 Banjarnegara earthquake with the estimated damage to buildings obtained using HAZUS. The real damage is obtained from the field survey while the estimated damage is obtained from the HAZUS modeling. The object of this research is the unreinforced masonry low-rise buildings (URML) in Kasinoman Village, one of the villages that suffered the most subjected to the 2018 Banjarnegara Earthquake. The result of this study indicates the actual damage has a higher mean damage ratio (20,40 %) compared to the estimated damage (11.66%). HAZUS is developed according to the performance and experimental data of the buildings in the US therefore it might not be compatible with the building in Indonesia, especially surveyed buildings in Banjarnegara. The reason is the buildings in the US fulfilled the earthquake-resistant building provision meanwhile the surveyed buildings did not.
