All spanning tree protocols are layer-2.  As for VPN's, those are typically implemented at layer-3.  Which means STP is not a factor.  However, there are some VPN's that are setup as Layer-2. In those cases, it's possible that STP could transit the tunnel. It would depend on the VPN though.

If VPN are set up as layer 2 , can i understand as two different geographical area can communicate with each other?
since there are in layer 2 is that mean 2 different vlan cannot comunicate with each other via VPN?

That doesn't have anything to do with spanning-tree.
Whether a VLAN can transit a layer-2 VPN will depend on what type of VPN.
