Abstract

A series of earthquakes with the mainshock on July 29th, 2018, August 5th, 2018 and August 19th, 2018 occurred in Lombok island. These earthquake has caused 559 fatalities, 1,478 people injured and 185.483 of buildings damaged in the Lombok and Sumbawa island. All type of earthquake hazards occurred namely ground shaking, minor fault surface rupture and collateral hazard such as liquefaction and landslides. Earthquake shaking felt strong in Lombok Utara and Lombok Timur with earthquake intensity scale of VIII MMI (Modified Mercally Intensity). Earthquake on July 29 th , 2018 with magnitude of M 6,4 result rupture zone 218,7762 km2, earthquake on August 5 th, 2018 and onAugust 19th, 2018 with magnitude of M 7,0 result rupture zone 758,5776 km2.

Abstract

The coast of Gunung Kidul is divided into two type of beaches, straight beaches with cliffs and sloping beaches with bays. Even though the sloping beach is a small part of Gunung Kidul region, but there are high intensity of activities, such as settlements, fishing, and tourism area. The tsunami inundancy mapping through the modeling for narrow beaches with bays requires detailed topographic data obtained through aerial photography using drone. The source of tsunami generation uses earthquake scenarios from the megathrust zone in southern Java with magnitudes of 7.0, 7.5, 8.5 and 8.7. The modeling results show that tsunami with a maximum height can threaten the facilities and buildings in the coastal area where the reasearch takes place, including Baron, Krakal, and Sadeng beach.
