Mediterranean / Greece · GR
Santorini sits on the rim of one of Europe's most studied active volcanoes — and the wider Greek islands face wildfires, heatwaves and seasonal strikes that disrupt ferries. TravelAlert aggregates live data from EMSC, USGS, GDACS, the Greek Civil Protection authority and the WHO so you know about earthquakes, volcanic alerts, wildfires, heatwaves and transport strikes the moment they happen.

Hazard-specific orientation gathered from public guidance by USGS, NOAA, WHO and similar agencies. This is general information, not professional safety advice — always follow instructions from local authorities and official emergency channels for your location.
Drop, cover, hold. Older buildings in Fira and Oia have variable seismic resistance — modern hotels are generally well-built. After shaking, avoid walking close to caldera-edge cliff paths until you've checked for fresh rockfall.
Santorini's volcanic system is constantly monitored. Minor unrest does not equal eruption. Follow Greek Civil Protection advisories and avoid visiting Nea Kameni (the central crater islet) during alert phases.
Santorini itself has lower vegetation than many Greek islands, but ferry connections to islands with active fires (Rhodes, Corfu, Evia) can be affected. Follow 112 emergency-alert SMS and Civil Protection advisories.
Hydrate aggressively, avoid sun between 12:00 and 17:00, and check whether the Akrotiri archaeological site or other outdoor venues are open before traveling — closures are common at 40°C+.

Open the live alerts above. Santorini is generally very safe for tourism. The main practical risks are earthquakes, heatwaves and ferry disruption — all manageable with awareness.
No imminent eruption is forecast. The caldera is constantly monitored; minor unrest occurs every few years without escalation. We surface any Greek Civil Protection alert immediately.
M4+ events are common in the southern Aegean. The vast majority are not felt strongly on Santorini. Stay in a modern hotel and avoid caldera-edge walks immediately after any noticeable shaking.
Santorini itself has limited vegetation, but neighbor islands can be affected. Check 112 SMS alerts and Civil Protection advisories in July–August before island-hopping.
Possible. Greek ferry and airport strikes happen with short notice. Have flexible timing or fly to/from Santorini Airport (JTR) rather than relying on ferries to make a tight connection.
May, early June, September and October. Warm but not extreme, lower wildfire risk and calmer overall conditions than peak July–August.
