Mount Labo has been the object of an extensive geothermal exploration program.[2]
Eruptions
Mid-Pleistocene eruptions beginning about 580,000 years ago formed lava domes on the northern side of the complex. The present edifice was formed beginning about 270,000 years ago, and flank lava dome emplacement took place from about 200,000 to about 40,000 years ago.[2]
The latest activity from Mt. Labo produced pyroclastic flows from the summit cone about 27,000 years ago. There have been no eruptions since.[2]
