A pyroclastic flow descended into the Achupashal drainage (NW). At night incandescent blocks ejected by an explosion traveled 1 km down the flanks. On 5 February clouds prevented views of the volcano, though loud "cannon shots" were heard in Baños and Juive, and ashfall was reported in Manzano (8 km SW).
