Sfondo

Irazú is a massive stratovolcano covering more than 500 sq km with at least 10 flank cones on the southern flank, all being older than at least 14,000 years when a massive lava flow (the "Ceravantes" flow) was erupted.
All known eruptions from Irazú during the past 10,000 years have been explosive and originated from the summit craters that show a migration to the W over time. The historically active crater contains a small acid lake of changing size and color.
