Global Volcanism Program | Image GVP-04002
A period of Strombolian activity began at Pacaya in 1965 and continued for over 25 years. Nighttime explosions are often visible from Guatemala City, 40 km N. The accumulation of ejecta from frequent explosions periodically increases the height of MacKenney cone after it has been partially destroyed by intermittent larger explosions. This November 1988 photo also shows a lava flow descending the west flank (right).
