Determination of Absolute Gravity Values using a FG 5#210 in Bandung and Yogyakarta, Indonesia

Abstract

In November 2002, we carried out absolute gravity measurements for the first time in Bandung and Yogyakarta, Indonesia. We could success fully obtain the absolute gravity values for the two gravity stations. The gravity value deter mined for Bandung is 977976701.2 ± 0.1 μ gal (1, i gal= 10^-8 ms^-2) and that for Yogyakarta is 978203093.5±0.4, μgal. Determined absolute gravity values will contribute not only to the establishment of a precise gravity network in Indonesia but also to the detecting of gravity changes caused by seismic and volcanic activities.
