7.5 Papua New Guinea earthquake

612.....
Revelation 6:12 talks about the Great Earthquake...

Why are there so many earthquakes in the Ring of Fire? 
Ring of Fire=55(rev red) and 107
Earthquake=44, 55(rev red) and 107

The epicenter was 55 miles south of Porgera? 
Porgera=44

I keep seeing articles refer to Papua New Guinea as "PNG" as well. 
PNG=44(reverse) and 107(Jewish)
Aftershocks=44
