A hundred homes in the Groningen village of Winsum are to be urgently inspected after a serious ‘construction shortfall’ was discovered in an empty property in the earthquake area.

Dutch gas company NAM says it will speed up the inspection process following the discovery in an effort to head off earthquake-related damage, news agency ANP reports. Winsum and the surrounding area have been hit by a string of quakes as the ground settles following natural gas extraction.

The buildings earmarked for inspection were all built by a construction firm named Jarino. It is not clear how many Jarino properties are in nearby villages or what the construction problems are.
