A small spatter cone ejects incandescent lava 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 7-10 March 1989. This eruption removed the upper 75 m of MacKenney cone and enlarged the 50 x 75 m crater to the 200 x 350 m seen here.
