Patti, I can´t see it eiter, not now. Very irregular, but saw some great footage earlier.
Scientsts cannot really predict what will happen. They can just record all the earthquakes (thousands and thousand!), measure the stream, such things, but they have no idea what will happen tomorrow.
This is a highly active volcanic area. The whole system is HUGE. There are many volcanoes - some years in between eruptions, but irregular.
Just checked the cam - it is on now!
