| Comments: | When I arrived at 0455 there was audible boiling in the tube, which ended about 0515. 5/19 audible boiling ended 75 minutes after the 1100 eruption started. Yesterday there was no post-eruptive boiling from a pool a few inches below overflow. If that type of activity happened with this morning’s eruption, estimated start of the eruption could be an hour or more earlier. |
