A number of glaciers flow down from the ice cap, their number variously estimated to be 15, 17 and 23. Some glaciers have been named; on the southwestern flank two glaciers are known as 1 and 2, three 1 through 3 and six 1 through 6. Eighteen separate accumulation areas have been found as well. There are no substantive valley glaciers presently on Coropuna and some glaciers, especially in the eastern side, emanate from cirques. The ongoing downward movement of the ice on Coropuna produces icequakes.
