Earthquake Felt Across Switzerland at 04:24 AM, Confirms Swiss Seismological Service

On the morning of Sunday, April 26, 2026, a magnitude 3.8 earthquake struck eastern Switzerland, with its epicenter located approximately 6 kilometers east of Walenstadt in the canton of St. Gallen. The quake occurred at 04:24 local time at a shallow depth of about 2 kilometers, according to the Swiss Seismological Service (SED) at ETH Zurich.

The Swiss Seismological Service reported that the tremor was widely felt across eastern Switzerland, particularly in the Seeztal and Alpenrheintal regions, due to its shallow depth. The service confirmed the event in its latest earthquake list, noting the quake as the strongest recorded in the country so far in 2026.

Following the earthquake, authorities initiated inspections of unstable rock formations in the Walenstadt area to assess potential hazards. SWI swissinfo.ch reported that officials were conducting evaluations to ensure public safety in the aftermath of the shaking.

The SED maintains real-time monitoring of seismic activity across Switzerland and integrates its findings into the national earthquake mitigation action plan. Its latest data shows a series of smaller tremors in the region in the days preceding the April 26 event, including multiple quakes near Gelterkinden in Basel-Landschaft and repeated activity in the Sargans area.

As of the morning of April 26, no reports of injuries or significant structural damage had been confirmed. The Swiss Seismological Service continues to monitor the situation and advises the public to report any felt shaking through its official channels.
