“…Further, a study on the seismic vulnerability map for Lombok Island with the PSHA method in the form of a PGA value finds out how far the effect of the earthquake source is on Lombok Island [24]. Ground acceleration mapping using the probabilistic seismic hazard analysis method in Nusa province found west southeast in the megathrust zone [25]. There has been no research using the Zhao attenuation function for destructive mapping earthquakes in NTB.…”

NTB is a group of small islands located between the earthquake zone, namely in the south there is a subduction zone of the Eurasian and Indo-Australian plates and in the north, there is a back-arc fault or Flores Thrust. Earthquakes in this area are very active in the form of shallow tectonic earthquakes of large magnitude, so the risk of disaster is very high. Based on this, our research aims to map the distribution of destructive earthquakes using the attenuation function Zhao, released in 2006. The Zhao attenuation function has been applied to earthquake sources in subduction zones which are inputs for seismic hazards in various parts of the world, because the distance uncertainty factor used has better accuracy. The distribution of earthquake epicenter points in the West Nusa Tenggara region is clustered in four places, namely the Eurasian and Indo-Australian plate subduction zones in the sea south of the West Nusa Tenggara islands, the non-volcanic zone to the south of the West Nusa Tenggara islands, the volcanic zone to the east, and the Back Arc Thrust zone in the waters north of the NTB islands. Meanwhile, the hypocenter distribution is spread majorly on the Eurasian plate. Most of the islands of West Nusa Tenggara are characterized on the MMI VII-VIII intensity scale, and only a small part is characterized on the V-VI MMI intensity scale. The implications of the results of this research are useful in disaster mitigation, so it is hoped that there will be a reduction in disaster risk.

“…Indonesia is a meeting point between the three major plates of the world, namely the Pacific Plate, the Eurasia Plate, and the Indian-Australian Plate commonly called Triple Junction. The Hindia-Australia Plate Movement annually is about 7 cm to the north and the Pacific Plate is about 12 cm each year to the southwest [1]. The impact of the movement of the triple junction plate causes the Indonesian archipelago to have a high level of earthquake so that it is prone to have tectonic earthquakes.…”

Indonesia is a disaster-prone country. It is proven by the occurrence of various disasters that continuously affect various regions, whether it is caused by natural factors (earthquakes, tsunami, floods, volcanic eruptions, landslides, hurricanes, etc.), or by non-natural factors such as various consequences of technological failure and human activity. Generally, the disasters that occur causing suffering to the community, both in the form of human loss of property and damage to the environment and the destruction of the results of development achieved. Earthquake disaster potential affecting West Nusa Tenggara Island consists of 2 parts, namely the Indo-Australian subduction zone in the south of West Nusa Tenggara and a back arc thrust in the north of West Nusa Tenggara. Therefore, the frequency of earthquake events in West Nusa Tenggara is high. One of these efforts is to reduce the level of social vulnerability. Social vulnerability is often forgotten in the earthquake disaster management process, some activities are more often focused on efforts to knowledge of building structures and physical problems. Social vulnerability analysis is the state of an area that is affected by physical, social, cultural, and environment to prevent, reduce in response to disasters. Earthquakes are natural disasters that cannot be predicted when they occur accurately, so there needs to be an effort to minimize the vulnerability of the community.
