Why there are weak earthquakes in Lower Saxony - Minor earthquake rattles Lower Saxony near gas extraction fields

A minor earthquake struck Lower Saxony in the early hours of this morning. The tremor measured 2.1 on the Richter scale and was centred near the Hamwiede and Weissenmoor natural gas fields. Such events are not uncommon in the region due to ongoing gas extraction activities.

The quake occurred in an area known for natural gas production. Underground stress from gas extraction can build up and release suddenly along fault lines, causing induced earthquakes. This process has led to similar tremors in the past.

Over the last five years, around 150 noticeable earthquakes linked to gas extraction have been recorded across Germany. Most of these happened in the North German Basin, particularly in Lower Saxony and Schleswig-Holstein. The region around Größenkneten saw multiple tremors between 2021 and 2023, with magnitudes reaching up to 2.5. More recently, the EXPOGAS facility in Bastorf experienced similar activity from 2024 to 2025.

On average, the seismological service detects about five earthquakes per year in this part of Lower Saxony. Around one-third of these are strong enough for residents to feel. Earthquakes in the area typically become noticeable once they hit a magnitude of approximately 1.9.

Today's tremor follows a pattern of induced seismic activity tied to gas extraction. Residents in the region have grown accustomed to occasional minor quakes, with roughly five recorded annually. The latest event aligns with previous observations, where around a third of such tremors are felt by local communities.
