The eruption begins prompting mass evacuations
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).
