This event was a classic lahar. The increase lava flowed under the glacier. This melt the ice and heated the water which pooled. Then it started
cutting a channel down the slope. Opening that long crevasse earlier. There was a dam holding back but you could see it punching holes and venting.
Then I saw a very small lahar not long before this main release of steamy hot water. I don't think there is any lava coming down the slope.
And I don't think they'll be a lateral eruption like Mt. St Helens. The volcano is subsiding. Even if it's being more vigorous at the moment. If
there was a bulge like the one preceeding the 1980 eruption, then that could very likely happen. I think the most likely event is a major landslide.
There seems to be lots of material almost hanging over a sheer vertical fall.
Keep watching. The whole side of the mountain may give and cascade down in a massive lahar. Today's was very modest in reality.
