Abstract
Analysis of a peak ground acceleration value and earthquake intensity in Banten Province has been carried out using historical earthquake data from 2008 to 2018. This research aims to describe a prone area of the earthquake. The specification of data was a magnitude > 5 SR and the depth 0-70 km. The Donovan method was used to analyze peak ground acceleration value and the earthquake’s intensity. According to the data obtained, 31 earthquake points with a maximum earthquake strength occurred on October 16, 2019, with a depth of 10 km and a magnitude of 6.48 SR. This earthquake was located in Ujung Kulon with coordinates -6.81 LS and 105.113 BT. Based on data analysis result was obtained a peak ground acceleration value and the intensity of earthquake maximum in The Pandeglang Regency with a peak ground acceleration value was 211.56 cm/s2, and intensity of scale VIII and a large risk level of three. While a peak ground acceleration minimum is located in the South Tangerang City was 62.82 cm/s2 with a scale of intensity VII and a moderate risk level.
Highlights
The Indonesian country is an archipelago state on the located encounter of three of the plate are Eurasian plate, Indo Australian plate, and Pacific plate [1]
In the south of the island of Java, the subduction path of the Indo Australian plate is relative to the north against the Eurasian plate, while the Pacific plate moves westward relative to the Eurasian plate and the Indo Australian plate
One step that can be done is to analyze the value of the peak ground acceleration and intensity of the earthquake that occurred in the Banten Province
Summary
The Indonesian country is an archipelago state on the located encounter of three of the plate are Eurasian plate, Indo Australian plate, and Pacific plate [1]. Based on the observations made, the researcher of the earthquake that occurred in Banten Province from 2008 until 2018 with magnitude is > 5 SR This amount is taken because it has caused damage to structures such as cracks in the wall. One step that can be done is to analyze the value of the peak ground acceleration and intensity of the earthquake that occurred in the Banten Province. Earthquakes with large forces do not occur often, they are still dangerous to human life This acceleration value indicates the level of risk of damage that will arise to the building.
