Abstract

Summary

North Sulawesi’s activities are mostly done by triple junction between Eurasian, Philippine and Pacific plates causing seismic activity in the north Sulawesi region. In addition to PGA data there is also one parameter that can be used to characterize the ground response during a earthquake that is PGV (peak ground velocity). PGV is the most frequent value in an area within a given time period due to an earthquake. The result of PGV observation value is obtained if the largest PGV value is 0.25667215 cm/s at the earthquake event of Northern Molucca Sea M 4.8 dated 19 November 2016. Then for the smallest PGV value of 0.000187953 cm/s at event Molusca sea M 4.8 dated 5 May 2016 which recorded maximum at north-south component at TMSI station. The average PGV observation value in North Sulawesi is 0.056756952 cm/s. Areas with large observational PGV values are Bitung, Bolaang Uki, and Kotamobagu districts. PGV values are only good for accurately representing intensity and state of the station for earthquake magnitude below M 6.0. For earthquakes with magnitude M 6.0 or greater it is recommended to keep using PGA to represent ground shaking when an earthquake happend.
