These two photos show the summit of Volcán de Colima from Nevado de Colima in 1909 (top) and 1913 (bottom). They dramatically illustrate the effects of a major explosive eruption on January 20, 1913, which removed nearly 100 m of the upper part of the cone and created a 450-m-wide crater that was at least 350 m deep. The eruption produced heavy ashfalls and pyroclastic flows that swept all sides of the Volcán de Colima. This continued the typical Colima cycle of century-long dome-growth and minor explosions culminating in a very powerful explosive eruption.
