Early today there was a rockfall inside the throat of Halema'uma'u. It caused a short lived ash eruption. Impressive!!!! I've never witnessed one quite this intense. Driving by today an hour or so after this happened, I saw a small ash plume, not as intense as this one. My little plume still impressed me.
It was after this ash eruption that scientists were able to get close enough to look down the volcano's throat and see the lava well below.
This little ash eruption is nothing compared to what would happen if the lava drops down below ground water level. Let's hope it doesn't. We're already having too much excitement around here.
