The main crater of Irazú volcano is about 700 m wide and 200 m deep. It is seen here from the summit of Irazú, with ash-covered Playa Hermosa (a largely buried older crater) at the lower right and the edge of Diego de la Haya crater at the upper right. Activity at Irazú has migrated to the west from La Laguna, a crater east of Diego de la Haya, to the currently active lake-filled main crater.
