Pacaya
All times are local (unless otherwise noted)
Extensive lava flows, bomb-laden Strombolian explosions, and ash plumes emerging from Mackenney crater have characterized the persistent activity at Pacaya since 1961. The latest eruptive episode began with intermittent ash plumes and incandescence in June 2015; the growth of a new pyroclastic cone inside the summit crater was confirmed later that year. The cone has continued to grow, producing frequent loud Strombolian explosions rising above the crater rim and ongoing ash emissions. In addition, fissures on the flanks of the summit crater have been the source of an increasing number of lava flows traveling distances of over one kilometer down multiple flanks during 2019 and into 2021. Increasing explosive and effusive activity during December 2020-February 2021 is covered in this report with information provided by Guatemala's Instituto Nacional de Sismologia, Vulcanologia, Meteorologia e Hydrologia (INSIVUMEH), multiple sources of satellite data, and numerous photographs from observers on the ground.
