Near-continuous mild Strombolian explosions, such as the one producing the small plume above MacKenney crater at Pacaya to the right, have been punctuated by periodic larger explosions that eject incandescent bombs and large blocks. These trees on the Meseta (foreground) were stripped of vegetation by the larger explosions. The MacKenney cone to the right has been growing since 1965 on the flank of the older cone to the left.
