The explosive eruption at the volcano continues.
The seismic activity has decreased, i.e. the number and frequency of earthquakes have lowered in comparison to 17 June, when the seismic energy continued to show ongoing elevated levels by that time.
Meanwhile, vulcanian-type eruptions continue to occur by generating grey dense ash plumes rising 3,600 ft (1,100 m) above the summit crater in the northwest direction. The near-constant degassing accompanies the eruptive activity.
It is inevitable to emphasize that the activity of the volcano may fluctuate and suddenly decrease to lower levels.

Nevado del Ruiz this morning. I haven’t seen video of it being this ashy before (most likely obscured by clouds) I wish I could speak Spanish Video: Defensa Civil Colombia on YT #NevadoDelRuiz #volcan #volcano #Colombia pic.twitter.com/ftxue5cjrm
