♥ stratovolcanoes are composed of alternating layers of lava and ash. ♥
a volcano that is very tall and is composed of many layers of hardened lava and ash..
the stratovolcano can go up to 5426m (17,802 ft)
After the aspect (I was in the Nea Kameni island) Santorini is not a stratovolcano.
the lava flows out, then solidifies and builds on to the volcano
