Abstract: We have made intensity and magnitude of earthquake forecasting models based on Autoregressive Integrated Moving Average (ARIMA) approachment and residual model using ARCH, GARCH and TGARCH of them in Bengkulu Province. In addition, we have mapped distribution of peak ground acceleration on bedrock. Peak ground acceleration value was obtained by mathematic calculating of Fukusima dan Tanaka equation. It was used earthquake history data in Bengkulu Province for 1970 to June 2016. The result of this interpretation showed that Muko-muko regency has the highest peak ground acceleration value (361-402 gal). It also allowed on western of North Bengkulu Regency.
