In the morning of the 16th of December there was an earthquake in the very south of Scandinavia. It was not very strong, around 4,2 according to Richter. But earth was moving and houses were shaken.
And how about Ladonia? As you can see on the map:
Map showing the Tornquist Zone of instability. Ladonia is the black mark.
But Ladonia is resting on a mountain of solid rock – and did not move at all.
