Studi Penentuan Percepatan (Acceleration) Tanah Daerah Ampana, Balikpapapan, Bone, Bulukumba, Bau-Bau Akibat Gempabumi Donggala 28 September 2018
Abstract
ABSTRACT
Ground acceleration that was caused by an earthquake can cause damage both physical
and material. The research aims to determine the value of ground acceleration and the effects
caused by earthquake. The data used was secondary earthquake data occurred at Donggala on
September 28 th, 2018 at 17:02:45 WIB, with the observation area Ampana (central Sulawesi),
Bau-Bau (South East Sulawesi), Bulukumba (South Sulawesi), Bone (South Sulawesi), and
Balikpapan (Balikpapan). Research data including epicenter coordinates data, coordinates of
observation area and the depth of earthquake. From this data are further calculated epicenter
distance and hypocenter distance. Ground acceleration value was analyzed by using the method
M. V Mickey, Esteva, Mc. Guirre RK, Donovan, Oliviera and Guttenberg then connected with
MMI scale. The results showed thatthe ground acceleration value of Ampana, Balikpapan and
Bone was between 0.0004 g – 0.0730 g with damage effects I-V according to MMI scale. For
Bulukumba and Bau-Bau was between 0.0003 g– 0.0220 g with damage effects I-IV according
to MMI Scale.
