Where can you see
Explore theoretical visibility around Vesuvius, between the Gulf of Naples, the Campanian plain and surrounding relief. Beyond the map, a viewpoint 143 km away with a modelled view of Vesuvius is checked below.
Calculated radius: 100 kmTheoretical visibility; actual views and access are not guaranteed.
Check your viewpoint
Choose an observation point to estimate visibility using the terrain model.
The Somma–Vesuvius volcanic complex rises above the Campanian plain near Naples. Mount Somma forms part of the surrounding relief, so the selected summit point and the intervening terrain matter when comparing directions on the map.
Across coastal directions, sea-level terrain does not remove Earth curvature. Urban obstructions and haze also affect actual views; this map does not establish access or safety on the volcano.
Beyond the map
The map stops at 100 km. This viewpoint, 143 km away, was calculated with this map’s summit target and the standard example settings: Copernicus terrain, Earth curvature and standard refraction (k = 0.13). This is theoretical visibility: weather, haze and nearby trees or buildings are not modelled.

Line of sight
Understand the map
Mountains and ridges can block the line of sight.
At long distances, Earth's curvature becomes significant.
A higher observation point can dramatically increase visibility.
Sightelo samples observation points within 100 km of the summit, using surface elevations, Earth curvature and standard atmospheric refraction. This is a calculation assumption, not a prediction of real atmospheric conditions.
Copernicus DEM is a surface model: buildings and vegetation may influence its elevations, but Sightelo does not model them individually. Local obstructions remain imperfectly represented. Weather, clouds, haze and aerosols are not predicted.
