Lava flows erupted in September 1998 cover the floor of the caldera moat of Pacaya volcano. The caldera wall here is about 100 m high. Frequent lava flows from MacKenney cone, whose slopes are visible at the right, have been gradually filling the caldera moat, whose floor is many tens of meters higher than it was a decade ago. Eruptions from MacKenney cone have been more-or-less continuous since its formation in 1965. The ridge in the foreground is the crater rim of Cerro Chino.
