Erdbebenkreuz ("Earthquake cross") in Reinach. The 1356 Basel earthquake is the most significant seismological event to have occurred in Central Europe in recorded history [1] and had a moment magnitude in the range of 6.0–7.1. [2] This earthquake, which occurred on 18 October 1356, is also known as the Sankt-Lukas-Tag Erdbeben [3] (English ...
The Swiss Seismological Service (German: Schweizerischer Erdbebendienst (SED), French: Service sismologique suisse, Italian: Servizio sismico svizzero, Romansh: Servizi da terratrembels svizzer) at ETH Zurich is the federal agency responsible for monitoring earthquakes in Switzerland and its neighboring countries and for assessing Switzerland's seismic hazard.
The 1584 Aigle earthquake occurred on 11 March at 23:00–23:30 local time in Switzerland. The earthquake had a moment magnitude of 5.9–6.4 and maximum Modified Mercalli intensity of VIII ( Severe ). The shock generated a tsunami in Lake Geneva. It was followed by 25 aftershocks in the following days. An aftershock on 14 March triggered a ...
The largest was a 5.9 M w. The 1946 Valais earthquake struck on 25 January at 17:32 local time with an epicenter region in Sierre, near the capital city of Sion in Valais, a canton in Switzerland. The earthquake had an estimated moment magnitude (M w ) of 6.2 and a maximum Modified Mercalli intensity of VIII ( Severe ).
Earthquakes occur frequently in Utah, though they tend to be small (below a 5.0 magnitude). The highest-risk zone is along the Wasatch Front , where most of the state's population is located. The larger cities include the state's capital, Salt Lake City , as well as Lehi , Ogden , Orem , Provo , Sandy , and West Valley City .
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by seismotomography imaging technique and detections using space satellites from outer space — they rely mainly on the analysis of written sources, observations of shaking objects and ...
