Four options ...
1. All the recent explosions are a series of coincidental 'accidents'...
Or
2. The explosions could be natural but a new development (static buildup occurring in multiple fuel tanks/gas lines)
Or
3. The Explosions are man made (some group causing these explosions using energy or frequency weapons).
Or
4. The explosions are being caused by large pockets of released methane (natural gas) from above the planets crust a few miles down in the Earth .
--------------------
Option 3 is a bit far fetched.. but with the way things are bouncing back and forth between the US, Russia, and China.. worthy to keep on the back burner for future thought. Don't discount it as a possibility I should say.
Option 4 does not explain the fuel tanks exploding, or the ships/helicopter/gas line/p propane tank explosions recently.

Link to my public facebook page -- containing multiple explosion reports over the past few weeks: Look at how many there are -- US, Russia, China ... strange.
