A high ash-bearing eruption column towers above Colima volcano on March 7, 1903 in this view from the south. A large explosive eruption on February 15 produced abundant ashfall and pyroclastic flows. The light-colored area descending diagonally down the flank to the left may be the path of these pyroclastic flows. More than 20 large explosions, including this one on March 7, took place between February 15 and March 14.
