Odd earthquake swarm in Central Europe hints at magma bubbling below the surface


An odd earthquake swarm on the border of Germany and the Czech Republic may hint at magma moving deep below the surface. 

The quakes are in Vogtland, a region known for regular, low-level earthquake swarms. These swarms tend to last several weeks and lead to mostly mild shaking. The largest known quakes from the area are around magnitude 4.5, said Torsten Dahm, a geophysicist at the GFZ German Research Centre for Geosciences who’s leading a project monitoring this region.
