I draw attention to the disparity in the effects of this quake felt many kilometres away, and the Aceh quake of December 26th 2004 reported as9.3 ie 100 times as big!
Aceh was not a natural quake! It was merely 6 or 6.3 as initially reported.
I am unable to see any results or comments on undersea nuclear testing, but it is possible that a nule was used in order to get wuicker access to the oil in this disputed province. The local civil war stopped immediately after.
Collateral damage? 100,000 in addition to the 150,000 in Aceh. Shame!
