KNMI: Netherlands Logged 59 Earthquakes in 2025, Up From 47
The uptick reflects natural fault activity in Limburg rather than renewed gas extraction.
Overview
- Induced earthquakes fell to 35 last year from 40 a year earlier, according to KNMI monitoring.
- Groningen recorded 31 events versus 36 in 2024 as seismicity persists despite halted gas production.
- The year’s strongest mainland quake was magnitude 3.4 near Zeerijp in Groningen in November 2025, among the region’s strongest on record.
- Limburg registered 24 natural quakes, up from seven in 2024, including a small swarm near Heerlen and multiple shocks near Herten, with a 2.4 event at Kerkrade on January 3.
- In the Caribbean Netherlands there were 93 natural quakes, down from 102, with the strongest at magnitude 6.6, and these figures are tracked separately from the mainland.
