Location
Cause → Event → Consequence
The earthquake originated from seismic activity along the Lower Rhine Graben, a tectonically active rift system in northwestern Europe. It was part of a sequence of quakes recorded in September 1692, reflecting ongoing extensional faulting in the region beneath what is now eastern Belgium.
On 18 September 1692, an earthquake measuring approximately 6.2 on the Richter scale struck the area northwest of Verviers, then within the Prince-Bishopric of Liège. The event was widely felt across modern-day Belgium, England, Germany, the Netherlands, Luxembourg, and France, with the greatest destruction concentrated in the northwestern environs of Verviers.
Parish records and historical accounts document substantial damage in the northwestern Verviers area. Researchers at the Royal Observatory of Belgium subsequently identified this event as the strongest known earthquake in Western Europe north of the Alps, giving it lasting scientific significance for the study of seismic hazard in the region.
