Strongest Earthquake in Years Jolts Groningen, Rekindling Gas Extraction Concerns
Table of Contents
A magnitude 3.4 earthquake struck the Groningen province of the Netherlands overnight, marking the third strongest seismic event ever recorded in the region and raising renewed anxieties about the ongoing effects of gas extraction. The quake, felt across a wide swath of the province and beyond, occurred at 1:16 a.m. local time, with an epicenter near Zeerijp, approximately 10 kilometers west of Delfzijl. A smaller magnitude 2 aftershock was detected at 6:39 a.m.
Residents Report Widespread Shaking
The earthquake was reported to have been felt as far away as the German and Drenthe borders, according to reports received by regional broadcaster RTV Noord. Hundreds of residents contacted the station’s earthquake detector, indicating the breadth of the impact.
One resident of Zeerijp described the event as a “terribly loud bang,” stating they had “never experienced it like this before.” A camera in the resident’s home captured footage of the shaking. Another individual, driving at the time of the quake, reported losing control of their vehicle twice due to the force of the tremors. A mother in ‘t Zandt recounted a terrifying experience while bottle-feeding her three-month-old baby, with objects falling and lights activating unexpectedly.
Lingering Effects of gas Extraction
The tremors are directly linked to decades of gas extraction from the Groninger gas field,which began in the 1960s. while extraction has been considerably reduced over the past two years, experts warn that the risk of earthquakes persists.
“There is still tension in the subsurface due to the gas extraction at the time,” explained a KNMI seismologist. “Every now and then that tension is released by fractures in the gas field; that is an earthquake.”
The latest event is particularly disheartening for residents who had hoped that curtailing gas extraction would bring an end to the frequent seismic activity. As one observer noted, “This blow last night is not only physically, but mentally also a heavy blow.”
Historical Context and Recent Activity
The last major earthquake in Groningen, with a magnitude of 3.4, occurred in Westerwijtwerd in 2019. However, this latest quake was reportedly slightly stronger. The strongest earthquake ever recorded in the region occurred in 2012 near Huizinge, reaching a magnitude of 3.6.
Why did it happen? Decades of natural gas extraction from the Groninger gas field created subsurface tension.This tension released as fractures, resulting in earthquakes.Who is affected? Residents of Groningen province, and to a lesser extent, areas bordering Germany and Drenthe, experienced shaking and potential damage. What occurred? A magnitude 3.4 earthquake struck near Zeerijp,followed by a magnitude 2 aftershock. How did it end? While gas extraction has been reduced, the risk of earthquakes persists, and authorities are assessing damage.There is no definitive “end” in sight, as the subsurface continues to adjust.
