| Notes | Slide is looking from the ridge right around the active throat of the volcano down to, at that point, the active vent area of the dome where the dome was later to grow. This is where, right now, the volcanic lava is coming out of the volcano throat. This is now currently at the bottom of where the dome has been built. We were going to go down and sample the gases coming out of this area, but this jet, shown here, would pulse suddenly. White gases were coming out with very high velocities. It would quiet down and then another big "whoosh" of gases would be coming out. My students and I were scared about going down there, so we decided to take the safe way and to sample out in front of this area and not go down that dangerous region. Again, we were very, very nervous this whole time, and so there was just nothing but panic in our thoughts about if this will blow up. As we see later, that was a real, real worry that we had and we didn't realize how real it was until later. But this was the area where we decided we were close enough where we were and we weren't going any closer. |
