A small spatter cone ejects incandescent bombs at the bottom of MacKenney crater in early February 1990. Activity had resumed at Pacaya in early January after a long quiescence following a major explosive eruption March 7-10, 1989. This eruption removed the upper 75 m of MacKenney cone and enlarged the 50-75 m wide crater to the 200 x 350 m widths seen in this photo.
