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) | Outside mapped flood areas; nearest is 1.5 km away. Within a zone of potentially high flood risk |
| Wildfires | 2 recorded fires within 5 km (EFFIS, 2016–2026). Nearest burnt area: 22 Aug 2023 (6,057 hectares), 1.2 km away |
| Earthquake hazard (ESHM20) | Expected ground shaking: 0.27g · moderate. The figure is for rock; soft ground shakes harder. |
| SEVESO sites | EYDAP – lower tier, 2.9 km away |
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.
2021 zone price
The point lies in a zone with a tax value of 950 € per m² (objective value system, 2021).
2021 tax zone price (the objective value system), not a market price; market prices are usually higher. A property's official value applies coefficients for floor, age and frontage.
