CENAPRED reported that each day during 17-23 March there were 74-182 steam-and-gas emissions from Popocatépetl, some of which contained minor amounts of ash. An explosion at 2210 on 17 March ejected incandescent material onto the flanks and produced an ash plume that rose 1.2 km above the crater rim and drifted SE. Minor ashfall was reported in the municipalities of Tetela del Volcán (20 km SW), San Andrés and Hueyapan (16 km SW), and Ocuituco (24 km SW) during 17-18 March. Some emissions were accompanied by incandescent material ejected out of the crater between 2229-2315 on 18 March. An explosion at 1928 on 19 March ejected incandescent material a short distance from the crater. On 22 March an ash plume rose 1 km and drifted S and ejected incandescent tephra fell onto the flanks at a distance of 800 m from the crater. The Alert Level remained at Yellow, Phase Two (middle level on a three-color scale).
