[Available in DE/FR] Erdbeben bei Monthey (VS)

In der Nähe von Monthey (VS), südwestlich von Aigle, wurde am Dienstag, 25. Oktober 2022 um 21.11 Uhr (Lokalzeit) ein Erdbeben der Stärke 1.6 in einer Tiefe von etwa 1.5 Kilometern gemessen.

Beim Schweizerischen Erdbebendienst an der ETH Zürich sind vorwiegend Verspürtmeldungen aus Monthey (VS) und der näheren Umgebung eingegangen. Ein Erdbeben der Stärke 1.6 ist normalerweise für Menschen nicht spürbar. Aufgrund des Zeitpunkts des Bebens am späteren Abend, wenn viele Leute Zuhause einer ruhigen Tätigkeit nachgehen sowie seines untiefen Erdbebenherdes verspürten es viele Personen. Es gingen zudem vereinzelt Berichte über Knallgeräusche ein. Solche Geräusche entstehen, wenn Erdbebenwellen an die Oberfläche treffen und sind eine häufige Begleiterscheinung von Erdbeben. Die Schwingungen des Bodens werden in die Luft übertragen und erzeugen Schallwellen. Knallartige Geräusche entstehen, wenn relativ viel Energie in hochfrequenten Wellen an die Luft abgegeben wird.

[Available in DE] Earthquake close to Triesenberg (FL)

[Available in DE] Earthquake close to Triesenberg (FL)

Am Freitag, dem 14. Oktober 2022 hat sich um 17:33 Uhr (Lokalzeit) bei Triesenberg (FL) südöstlich von Vaduz in einer Tiefe von ungefähr 2 km ein Erdbeben der Magnitude 3.1 ereignet.

Die Erschütterungen waren vorwiegend im Gebiet um Triesenberg, aber auch in Triesen, Vaduz, Schaan und Balzers gut zu spüren. Zudem haben Personen aus weiteren Gemeinden, vorwiegend im Rheintal im Umkreis von ca. 10 km, das Beben wahrgenommen. Bis eine Stunde nach dem Erdbeben sind beim Schweizerischen Erdbebendienst (SED) an der ETH Zürich über 300 Meldungen aus der Bevölkerung eingegangen. Bei einem Erdbeben dieser Stärke sind in der Regel keine Schäden zu erwarten.

Das Beben gehört zu einer Serie von Erdbeben bei Triesenberg, deren bisher grösstes am 01. September 2022 stattfand und eine Magnitude von 3.9 aufwies (siehe Aktuell-Beitrag vom 01.09.2022). Das Beben wurde damals von einigen spürbaren Vor- und Nachbeben begleitet. Weitere Erdbeben in den nächsten Stunden und Tagen sind nicht auszuschliessen, die Wahrscheinlichkeit von deutlich grösseren Beben mit Schadenfolgen ist jedoch klein.

20 seismic stations in Bosnia and Herzegovina contribute to the initiative “AdriaArray”

The Swiss Seismological Service (SED) at ETH Zurich is now part of a new European initiative called AdriaArray. The international collaboration with teams across Europe aims to seek answers to fundamental questions related to plate geodynamics and the deformation of the Adriatic Plate. This microplate stretches throughout Eastern Italy and borders Switzerland and Austria, and goes all along the coast of the Balkan countries to Greece. Millions of years ago, the collision of the Adriatic and Eurasian plates led to the formation of the Alps. Up to now, the Adriatic Microplate constantly rotates counterclockwise against the Eurasian plate, which is the cause of many earthquakes in the Mediterranean region.

In the framework of the AdriaArray initiative, the research groups will apply different methods to unravel the structure of the crust, lower lithosphere, and upper mantle in the next four years. These efforts will increase the understanding of the European lithosphere's development which is particularly complex in the Mediterranean region due to the arrangement of the various microplates. To this end, a dense temporary network of seismic stations will soon cover the entire Adriatic plate in south-eastern Europe, providing data about the earth's movements. The SED contributes to this project by operating 20 broad-band temporary stations in Bosnia and Herzegovina, which the SED group deployed this summer together with local colleagues from Republika Srpska and the Federation of Bosnia and Herzegovina.

The AdriaArray initiative can be seen as a follow-up to the successful multidisciplinary AlpArray project that started in 2016. After the project's end in 2019, AlpArray has moved beyond the seismological experiment to a stage where the wealth of new data is being interpreted and debated. All the insights from this previous research will continue and further grow in the next four years of the AdriaArray's initiative.

Earthquake felt near Vallorcine (F)

Earthquake felt near Vallorcine (F)

An earthquake of magnitude 3.7 was observed near Vallorcine (France, close to the Swiss border), at a depth of about 6 kilometers on Sunday morning, September 27, at 8:18 local time.

In Switzerland, the earthquake was felt mainly in the region of Martigny, partly also in other settlements of the Rhone valley and its southern tributary valleys. The Swiss Seismological Service has received about 100 felt reports within the first hour after the event. In case of an earthquake of this magnitude, no damage are expected, nor was reported.

The region of Vallorcine is regularly hit by small earthquakes, among which felt ones nearly every year. The largest events happened on September 8, 2005 (magnitude 4.9) and June 23, 2020 (magnitude 3.8).

Earthquake Country Switzerland

Earthquake Country Switzerland

Switzerland experiences between 1'000 and 1'500 earthquakes a year. Swiss citizens actually feel somewhere between 10 and 20 quakes a year, usually those with a magnitude of 2.5 or above. Based on the long-term average, 23 quakes with a magnitude of 2.5 or above occur every year. Find out more about the natural hazards with the greatest damage-causing potential in Switzerland.

Earthquake Hazard

Earthquake Hazard

In Switzerland, earthquakes are the natural hazard with the greatest potential for causing damage. They cannot currently be prevented or reliably predicted. But, thanks to extensive research, much is now known about how often and how intensely the earth could shake at a given location in the future. Consult a variety of different maps using our interactive web tool to find out how likely certain earthquakes are in Switzerland.

About Us

Swiss Seismological Service (SED)

Swiss Seismological Service (SED)

The Swiss Seismological Service (SED) at ETH Zurich is the federal agency responsible for monitoring earthquakes in Switzerland and its neighboring countries and for assessing Switzerland’s seismic hazard. When an earthquake happens, the SED informs the public, authorities, and the media about the earthquake’s location, magnitude, and possible consequences. The activities of the SED are integrated in the federal action plan for earthquake mitigation.

Earthquake Monitoring

Earthquake Monitoring

Around 10 to 20 times a year you will hear or read about an earthquake occurring in Switzerland. However, the vast majority of quakes recorded by the SED go unnoticed by the general public because they fall below the threshold of human perception and can only be detected by sensitive measuring devices. The Swiss Seismological Service (SED) operates a network of more than 200 seismic stations across Switzerland.
