| Comments: | GREAT minors that lead up to the eruption! VERY SHORT water phase. Wind direction at the start was to the SE so water came over the east end of middle deck. LOUD Steam phase was minutes after the start! Comparatively not much water down the SV channel or back side. No water down the NV runoff channel. @ 1H 45M SB is still in steam phase. no color changes in either vent. Height was measured at 330' - 360' per Ben VL. |
