Beschreibung:
The broad, well-vegetated edifice of Poás has three craters in a N-S line. The 2708-m-high basaltic-to-dacitic complex stratovolcano is cut by a N-S-trending fissure that extends to the lower northern flank, where a parasite volcano (the Congo stratovolcano) and several explosion craters, or maars, most of them lake-filled, have been created.Poás has two summit crater lakes. The southermost one, Botos, is cold, clear has not eruptied for about 7500 years. The other crater lake is geothermally heated and -after Kawah Ijen in Indonesia - is probably the world's second most acidic natural lake. Its pH is near zero.
