"Our office shook. Shaking in my chair. Strange earthquake," tweeted one witness, who identified herself only as Esther. "We've just had an earthquake, really felt it here this time!" another witness Aniek responded in another tweet.
Northern Groningen, which houses the European Union's largest gas field, has been plagued by a raft of tremors which increased as gas production rose in the region from the 1990s. The relatively low magnitude quakes are described as resulting from huge air pockets left underground because of gas extraction.
Angry residents say they are bearing the brunt of repetitive tremors that have damaged homes, farms and historical buildings. Early indications showed no major damage after Monday's quake, the NOS public broadcaster reported.
The strongest-ever quake in Groningen due to gas extraction was registered at 3.6-magnitude and hit the area in 2012, the KNMI said. That followed a 3.5 quake in 2006. But minor quakes - including five in Zeerijp village last month - have continued to shake the region.
