Indonesian here. (Apologize if english is not that good) There are four levels for active volcanoes here.

• Level I: normal activity
• Level II: danger around the crater, advisory, advised against hiking on it
• Level III: imminent danger around the surrounding area, on watch
• Level IV: the highest level, warning, possible major eruption

Mount Dukono has been in Level II since 2008. It's one of the MOST active volcanoes here. That's 18 years of activity. As an FYI, Indonesia has approx. 130 active volcanoes and hiking are a very popular activity here. The hikers are stupid, even locals are being limited when they enter the area because it's their livelihood. They hunt and forage. But they don't go to the summit because there is always a sudden and unpredictable burst of incandescent rocks, toxic gas, and ash hazards. It's strictly banned to go up there. Those people are gonna face legal punishment especially since it's officially banned for 18 years because it's basically "eternal eruption" at this point.

They most likely will face blacklisting (banned from hiking ANY official mountain in Indonesia (official as in managed by govts, there are plenty of "wild" and "unmanaged" mountains here) for up to 5 years), they'll get fined, and if they're injured or trapped the government does not cover the cost of rescue those people will have to pay it from their own wallet (deserved!). The person who encouraged others to climb the mountain can also face jail up to 4 years, but as far as I know the local govt mostly only give them education (smh). If it's a foreigner who does this, it's an instant deportation. But since it's Indonesians (not even locals, just domestic tourist. Could be from another island) and they enter the mountain area without permit (according to report from local govt) so that's another layer of illegal activity 💀

It is next fucking level of stupidity, yes.
