The BMKG reported a parameter update to the earthquake, which was initially 7.3 magnitude to 6.9 magnitude.
The earthquake was a shallow quake due to subduction activity of the Indo-Australian plate. The results of analysis of the source mechanism showed that the tectonic earthquake has a thrust fault mechanism.
