RESIKO GEMPA BUMI DI PROVINSI LAMPUNG
Research of the maximum horizontal acceleration of the ground motion was conducted suronding, within Lampung and situated at between coordinate 101o and 108o longitude, 2o and 7o latitude. The earthquake data were collected in 1990-2004 period. A Liwa earthquake in 1994 is as especial data. Gridding of the research area within interval 0,5o due to calculate and distribute of the maximum ground motion acceleration. The calculation is using Fukushima and Tanaka Equation. The values of the maximum ground motion acceleration of the Liwa earthquake in 1994 are compared with their intensities due to deternined the earthquakes risk. The comparison of the horizontal maximum of the ground acceleration with intensities for data 1994 should be formulated for the acceleration within Lampung and surrounding such as I = 0,002a + l,9828. Four classifications, there are (l) the very high risk if the ground acceleration is more than 2300 µm s2, (2) the high risk if the ground acceleration is between 2300 and 1300 µm s2, (3) the common risk if the ground acceleration is between 1300 and 300 µm s2, (4) the low risk if the ground acceleration is lower than 300 µm s2.
