The West Eifel volcanic field (SW of Bonn, Germany) is not far from NL and the last spectacular eruption there was 
about 9000 or so years ago (rather recently in geological terms).  And there have been other significant earthquakes in 
the region in recorded history.  The Lisbon quake in the 18th century was felt across much of Europe.
