Eruptions of Labial Geyser last for less than two minutes and are 25 feet (7.6 m) high. The usual interval between eruptions is 6 to 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 on surging becomes violent, and this eventually triggers an eruption. During the eruption, Labial jets up to 25 feet high at a sharp angle, another vent bursts up to 6 feet high, and a related springs splashes 1-2 feet high. Following the eruption, Labial continues to have bursts that spray water from the vent, and these rarely lead to a brief but full-force second or even third eruption.

Labial Geyser has two satellite geysers that react to Labial eruptions but have been seen to act independently as well. Their intervals are not predictable with durations of less than a minute. The east vent reaches 6 feet (1.8 m), while the west reaches 10 feet (3 m).
