An ash plume from Popocatépetl volcano on January 23, 2001 is blown to the south. The plume reached more than 9 km above sea level. Larger explosions the day before had produced plumes that rose 8 km above the 5426-m-high summit and pyroclastic flows that swept 4-6 km down the north flank. The large dark-colored area below and to the left of the volcano is a voluminous prehistorical lava field. Elongated Iztaccíhuatl volcano, its summit capped by snow, is visible at the lower right.
