Switzerland — Natural Disaster Report
Europe · Live status: High (43 active events)
Current situation: 43 natural disaster events are currently monitored in Switzerland, with a worst severity of Severe. Details, sources and timestamps are listed below.
Switzerland's alpine terrain concentrates hazards that Europe elsewhere experiences only in part: avalanches, rockfall, debris flows, landslides and glacial hazards all occur within a small area, and the country has developed some of the world's most advanced protective infrastructure and warning services in response. Retreating glaciers and thawing permafrost are destabilising high mountain slopes, producing events such as the 2017 Bondo landslide and the 2023 evacuation of Brienz. Flooding affects valley floors and lake shores, and summer heatwaves increasingly affect cities and alpine ecosystems.

Disaster displacement in Switzerland
356 internal displacements
Largest single event: 316 from mass movement, beginning 19 May 2025.
A displacement is a movement, not a person: somebody forced from home more than once in a year is counted more than once. These are movements caused by disasters only — displacement caused by conflict is counted separately and is not included here.
| Hazard | Displacements in 2025 |
|---|---|
| Mass Movement | 356 |
| Year | Displacements |
|---|---|
| 2025 | 356 |
| 2024 | 1,071 |

River flood forecast — Switzerland
No chance of exceeding even its 2-year flood flow in this forecast.
GloFAS alert level: Inactive · Peak expected: in 7 days (on 2026-10-26) · forecast of 19 Oct 2026
GloFAS forecasts are computer model output, published for information only. They are not a flood warning: only national and regional authorities issue flood warnings for their own area. A reporting point is a place on the model's river network, which may sit a few kilometres from the town it is named after. All 259 rivers →
What this site sees in Switzerland
| Source | Events here, last 12 months | What it will not tell you |
|---|---|---|
| WMO Alert Hub (national weather services) | 254 | Each warning comes from one country own alerting authority, so the scale is that agency scale and is not comparable between countries. Many agencies publish no coordinates, and those warnings are placed at the centre of the country rather than where the weather is - the area name is the real answer. |
| MeteoAlarm (EUMETNET) | 90 | Europe only. It publishes no coordinates at all, so every warning here is placed at the centre of its country and the area name is the only reliable indication of where it applies. |
| NASA FIRMS | 8 | Global, but it sees only what the satellite saw on its pass, and thick cloud hides fire. A quiet day here is not evidence that nothing burned. |
| European-Mediterranean Seismological Centre | 1 | Global for earthquakes, with the best coverage in Europe and the Mediterranean. It publishes nothing about any other hazard. |
| GDACS (European Commission / United Nations) | none | Global, but deliberately selective: it alerts on disasters likely to need INTERNATIONAL response. Serious local flooding that a national agency handles alone will not appear here. |
| US Geological Survey | none | Global for earthquakes above roughly M4.5, and denser where there are more seismometers. It publishes nothing about any other hazard. |
| NASA EONET | none | Global and curated rather than automatic, so it is slower than the raw feeds and carries far fewer events. |
| NOAA Tsunami Warning Centers | none | These two centres warn for the US and Canadian coasts and for the Pacific and Caribbean basins. The Indian Ocean and Mediterranean have their own warning centres, which are not read here. Their routine information statements - the ones that say there is NO tsunami danger - are deliberately not imported, so an empty tsunami list means no threat was issued, not that nothing was checked. |
| NOAA National Hurricane Center | none | The Atlantic and the eastern and central Pacific only. No typhoon in the western Pacific and no cyclone in the Indian Ocean or the southern hemisphere appears here; those come from GDACS and from national services. |
| ReliefWeb (UN OCHA) | none | Global, but it reports on humanitarian RESPONSE. It arrives days after an event rather than during it, and never functions as a warning. |
Not applicable here: US National Weather Service — Covers the United States only. It publishes nothing about any other country, so its absence from a country page is not an outage. ; USGS Volcano Hazards Program — United States volcanoes only - Alaska, Hawaii, the Cascades, Yellowstone, California and the Northern Mariana Islands. It says nothing about Indonesia, Iceland, Italy or anywhere else, so its silence about a foreign eruption is not a judgement about that eruption.
Frequently asked questions
What natural disasters are currently active in Switzerland?
There are currently 43 monitored natural disaster events in Switzerland. The overall risk status is High. See the live list on this page for details and sources.
What natural hazards does Switzerland face?
Switzerland's alpine terrain concentrates hazards that Europe elsewhere experiences only in part: avalanches, rockfall, debris flows, landslides and glacial hazards all occur within a small area, and the country has developed some of the world's most advanced protective infrastructure and warning services in response. Retreating glaciers and thawing permafrost are destabilising high mountain slopes, producing events such as the 2017 Bondo landslide and the 2023 evacuation of Brienz.
When is the main natural disaster season in Switzerland?
Avalanches December-April. Rockfall and debris flows increasing with permafrost thaw, especially in summer. Flooding May-August from rain and snowmelt. Heatwaves June-August. Storms with damaging hail in summer. Seasons shift from year to year; treat these as the usual pattern, not a forecast.
Which official agency issues disaster warnings in Switzerland?
Official warnings for Switzerland are issued by MeteoSwiss and SLF — Institute for Snow and Avalanche Research. Links to each are on this page. This site aggregates and reports; it does not issue warnings, and in an emergency the national agency is the authority.
Where does this disaster data for Switzerland come from?
Data is aggregated from official sources including USGS, GDACS (EC/UN), NASA EONET, ReliefWeb and national agencies. Every event links to its original source, and update times are shown on each record.
