Hawiian eruptive behaviour creates lava flows and an ash plume whilst seismic activity drops
Since the beginning of the eruption, on Sunday, September 19th 2021 (16:10 UTC), a total of 52 earthquakes have been located, of which at least 1 has been felt by the population with a maximum intensity III. The deformation of the topography has remained stable in recent days at a 22 cm vertical displacement (IGN, 2021). Since yesterday there has been a significant increase in ash emission. Tremor amplitude decreased around noon on 25 September, along with the intensity of the Strombolian explosions (GVP, 2021).
