There may be other options but amateur radio may be one of your best bets. There are frequencies for disaster communication. Many amateurs might give a helping hand. They also have the training and equipment to do so.
As for distance: My location is basically in the middle of Germany. I hold a class A license and a trainerīs license as amateur radio operator.
IIRC there are a couple of community members located in Europe (UK, Netherlands and maybe Spain)
