Greece — Natural Disaster Report
Europe · Live status: Low (1 active event)
Current situation: 1 natural disaster event is currently monitored in Greece, with a worst severity of Minor. Details, sources and timestamps are listed below.
Greece faces the highest seismic hazard in Europe, sitting on the Hellenic Arc where the African plate subducts beneath the Aegean. Large earthquakes and tsunamis have shaped its history, including the Bronze Age eruption of Thera (Santorini), one of the largest volcanic events of the past ten thousand years. Modern Greece experiences frequent damaging earthquakes, and its islands include the active volcanic centres of Santorini and Nisyros. Summer wildfires have become the country's deadliest recurring disaster: the 2018 Mati fire killed over 100 people, and the 2023 Rhodes and Evros fires burned unprecedented areas. Flash floods follow intense autumn storms.

Disaster displacement in Greece
79,073 internal displacements
Largest single event: 12,217 from wildfire, beginning 8 August 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 |
|---|---|
| Wildfire | 74,051 |
| Earthquake | 5,000 |
| Mass Movement | 22 |
| Year | Displacements |
|---|---|
| 2025 | 79,073 |
| 2024 | 60,423 |

What this site sees in Greece
| Source | Events here, last 12 months | What it will not tell you |
|---|---|---|
| WMO Alert Hub (national weather services) | 372 | 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) | 344 | 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. |
| European-Mediterranean Seismological Centre | 18 | Global for earthquakes, with the best coverage in Europe and the Mediterranean. It publishes nothing about any other hazard. |
| NASA FIRMS | 12 | 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. |
| US Geological Survey | 3 | Global for earthquakes above roughly M4.5, and denser where there are more seismometers. It publishes nothing about any other hazard. |
| GDACS (European Commission / United Nations) | 2 | 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. |
| 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.

Tsunami risk from Aegean earthquakes and volcanic collapse. Seasons shift from year to year; treat these as the usual pattern, not a forecast.
Which official agency issues disaster warnings in Greece?
Official warnings for Greece are issued by National Observatory of Athens — Geodynamics Institute. The link is 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 Greece 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.
