Chilean officials are now fearing that the volcano is in “worst case scenario” mode – although, they never mention what that might be: full-on caldera? topography-erasing ignimbrite? Pinatubo-scale eruption? However, the SERNAGEOMIN says the eruption has “reached its climax.”
The real problem right now is less the eruption (which is still a problem) but more the collateral issues like water/food supply that can be easily spoiled by ashfall. Look for this to become a humanitarian effort soon, but luckily the region isn’t densely populated. Upwards of 30-cm of ash has fallen on many parts of the area. Currently, 12,000 residents of the area have been evacuated.
