One or two people are asking about the difference between slow moving and fast moving and whether it's volcanologist speak. I don't know if some of you have seen videos of lava flows from Pu'u O'o before, but some of the lava flows from there are really fast, just like a really quick flowing river. The current one is much slower, a few hundred yards per day.
I'm pretty sure that's the definition HVO are using although I'll admit I don't know the threshold between fast moving and slow moving. For me, fast moving means you can't run away from it, slow moving means you can. When it comes to the June 27th flow, I think it's certainly the latter.
Edited - PW didn't like my attempt at at using the Hawaian name for Pu'u O'o with accents.
