It was serious quake with certain damage with some fatalities.
I could not find seismogram of Indonesia. The nearest one was of Philippines.
I could not get the whole picture of seismogram of this quake. Therefore, I cannot say this is explosion or earthquake.
All the quakes around there were very shallow including depth 10km that is the signature depth of Cleaning-up Operation on Reptilian Secret Underground/Undersea bases led by Galactic Federation of Light.
That means it is high possibility these quakes were Reptilian Undersea Base explosions and demolition.
