The eruption begins prompting mass evacuations

Data type: Geological report

Groups: Plume height – Lava flow activity – Uplift

Yesterday, ash emissions increased significantly, a series of powerful explosions began at 17:20, and shock waves were observed through the plume (GVP, 2021). Since yesterday, the ash column has exceeded 5,000 m in height above mean sea level. The deformation of the topography has remained stable in recent days. Since the beginning of the seismic activity, 22 cm of vertical deformation has been recorded at the GNSS station LP03 (IGN, 2021). Today, two new vents opened on the flank, pouring lava flow more than 1 km downslope.The eruption has produced a lava flow with several fronts, which after advancing at about 700 m / h during the first days, have been slowing down to less than 10 m / h (GVP, 2021).

This video shows lava flows moving down the steep side of the volcano and the slow creeping of the lava front towards homes on the 24th of September. Sourced from IGME (2021).
