One of the world's largest eruptions of the 20th century took place October 24-25, 1902 from Santa María volcano.  During the plinian phase detonations were heard in Costa Rica and an eruption column height of 27-29 km was measured.  During the day of October 25 much of the Pacific slope was in darkness.  Ashfall was primarily to the northwest and eventually reached Mexico City.  This photo shows an eruption plume on an unknown date from the city of Quetzaltenango, 10 km north of the volcano.
