Around here
Distances are in a straight line from the point OpenStreetMap records for the settlement and are not travel times. The nearest option that does not cross water is preferred. OpenStreetMap coverage is uneven.
| Category | Name | Distance |
|---|---|---|
| Hospital | unnamed in OSM | 2.0 km |
| School | unnamed in OSM | 2.4 km |
Beaches nearby
Within 10 km in a straight line, without crossing water. The class is the latest EU assessment (season 2024) and the history counts classified seasons since 2011.
| Beach | Water class | History | Distance |
|---|---|---|---|
| Riva Thirasias | Excellent | Excellent in 14 of 14 seasons | 96 m |
Getting there and around
The nearest mapped transport points in a straight line. The data holds no timetables or journey times; where an official source exists it is linked below.
| Kind | Name | Distance |
|---|---|---|
| Airport | Santorini (Thira) Airport "Zefiros" (JTR) (across the water) | 13.6 km |
| Ferry terminal | Riva | 77 m |
| Bus stop | unnamed in OSM | 2.0 km |
Rows marked "across the water" have no mapped option on the same side of the water within the search distance. The straight line crosses water, so the real journey is longer and may need a ferry or a long detour.

Context from the map
The same facts the Katatopisi map shows for the settlement's point, in the same words. They are regional data, not a survey or a safety guarantee.
| Topic | What is recorded |
|---|---|
| Flooding (YPEN hazard maps) | No mapped flood hazard area nearby |
| Wildfires | No recorded fire within 5 km in the data (EFFIS, 2016–2026). |
| Earthquake hazard (ESHM20) | Expected ground shaking: 0.27g · moderate. The figure is for rock; soft ground shakes harder. |
| SEVESO sites | No SEVESO site within 5 km |
Maps cover designated high-risk zones only, and only the low-probability scenario (1-in-1000 years); scenarios for more frequent floods are not included. “Outside” does not mean “safe”.
Mean peak ground acceleration with a 10% chance of being exceeded in 50 years (the 475-year return period), from the European ESHM20 model. It is a regional figure, not a ground study for this plot.
Fires: EFFIS (Copernicus), areas of roughly 30 hectares and above; the dates in our data run 2016–2026. Smaller fires do not appear.
