Overview
- KNMI measured a magnitude 3.4 main shock near Zeerijp, the third-strongest ever recorded in the province, followed by a 2.0–2.1 aftershock around 06:30.
- Water authority Noorderzijlvest is inspecting dikes, sluices and pumping stations within 10 kilometers of the epicenter and reported no visible damage or water-safety issues by midday.
- The municipality of Eemsdelta opened the Zeerijp village hall for residents to share concerns, while neighboring Het Hogeland directed people to information and support coaches.
- Authorities urge residents to file damage reports with the Instituut Mijnbouwschade Groningen, with full mapping of impacts and follow-up work expected to take weeks.
- Provincial commissioner René Paas called the quake a hard blow that ended hopes the shutdown would prevent strong events, and watchdog SodM notes a small (about 1%) chance of a ≥4.0 quake remains.
