. Eruptions of Labial Geyser last for less than one minute and reach about high. The usual interval between eruptions is 6-9 hours. On occasion, an eruption will be followed within 30 minutes by a second eruption. Before the eruption, the water rises and falls in the vent. During the last few minutes Labial's surging becomes violent, and this eventually triggers an eruption. During the eruption, three vents are active, with jetting at different angles. Labial jets up to high at a sharp angle, another vent bursts up to high, and a related spring splashes high. Following the eruption, Labial continues to have bursts that spray water from the hole, and these rarely lead to a brief but full-force second or even third eruption! Labial Geyser has two satellite geysers (Labial's Satellite Geyser) that react to Labial eruptions but have been seen to act independently as well. Their intervals are not predictable. Full eruptions are 12 to 15 minutes in duration, with the eastern vent dominating. The eastern vent reaches , while the western vent reaches . Minor eruptions, usually originating from the eastern vent, are less than one minute in duration and less energetic than full eruptions.
