Updates on volcanic activity (Smithsonian)

The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Pacaya report has been published on 31 Mar 2021 11:27.
INSIVUMEH reported moderate to s trong explosions at Pacaya?s Mackenney Crater during 24-30 March, accompanied by abundant ash plumes that rose to 2.9-4.5 km (9,500-13,000 ft) a.s.l. and drifted in multiple directions as far as 15-20 km. Resulting ashfall was reported in El Pepinal (7 km N), San Francisco de Sales (5 km N), El Cedro (9 km NNW), Calderas (3 km N), Mes?as Altas, Mes?as Baja (5 km NE), El Rodeo (4 km WSW), El Patrocinio (5 km W), and San Vicente Pacaya (5 km NW). The lava flow that began on 18 March was 2.5 km long, continuing down the SW flank; the height of the flow was 2.5 m with a width of 400 m, but the advancing front was 250 wide and set fire to nearby vegetation. Incandescent material ejected 150-300 m above the rim fell around the crater on 25 and 27 March. On 30 March ash plumes drifted 7 km S, causing ashfall in El Chupadero (2-2.5 km S) and Los Pocitos (5.5 km S).
