In our day adventure we are going to visit a geological phenomenon. We are going to get to know the dolinas of Didima.
A dolina (a word of Slovenian origin that means valley) is a special type of geological depression that is produced by the dissolution of the rock or by the collapse of the roof of a cave, forming hollows of circular shapes and of diverse sizes.
They are generally presented as wide pits, with more or less flattened bottoms.
The ruins of the Agios Stefanos basilicas are considered the most grandiose and best preserved, of all those found on the island of Kos, Greece. Next to it there is a paradisaical blue flag beach.
They are estimated to have been built between 469 and 554 after Christ, which were the two largest earthquakes recorded on the island and were destroyed by the latter.
They were built on stone, with reddish limestone of local origin, with white marble columns and ionic capitals.
Porto Hydra – The Venice of the Saronic Gulf. It is a residential real estate development. It has 3.5km of canals, more than 300 houses, 3 islands connected between themselves and 9 bridges. According to its official website, construction began in the mid-1970s and it is still expanding.
We visited the Stefanos crater, in the caldera of the volcano of the island of Nisyros.
The Stefanos crater has an elliptical shape with 185m at its narrowest point and 250m at its widest.
Its walls are 30 meters high and it is estimated to be between 3000 and 4000 years old.
The entire area has a deep sulfur odor.
The last eruptions of the volcano were between 1881-87 and were of the phreatic type. A phreatic eruption is one that occurs when the magma of a volcano, whose temperature is extreme (600 Cº-1170 Cº), comes into contact with the ground or a surface that contains water, which evaporates rapidly causing an explosion of vapor, water, ash, stones, etc.
