A Strombolian eruption at Pacaya volcano in Guatemala, November 1988. This time exposure shows the incandescent parabolic arcs of individual volcanic bombs explosively ejected from the vent. Larger bombs remain incandescent after they hit the surface of the cone and roll down its flanks. The orange line at the lower right is a lava flow extruding from a fissure on the upper NW flank of the MacKenney cone. Photo by Lee Siebert, 1988 (Smithsonian Institution).
