Which Countries are possible for the Doubles?

No this is not about football!
Tomorrow we expect DOUBLE and TRIPPLE earthquakes.
This means in the same place, (withing a degree) 2 or 3 earthquakes spaced out by an hour in time.
The following countrie pocess the ingredients to give this phenomenon.
If it is going to be one or two or more it depends on the stresses on earth right now.
The countries are:

• Vanuatu/Solomon Isl
• PNG
• Alaska 
• Br. Columa
• Iran 
• Nepal, but I have still have doubts on this.
