Mount Leonard Kniaseff, or simply Leonard Kniaseff (or Leonard Kniazeff), is a stratovolcano between the municipalities of Mabini and Maco in the province of Davao de Oro, island of Mindanao, Philippines.

It has a 2.03-kilometer (1.26 mi) diameter caldera lake called Lake Leonard. Amacan Thermal Area is located 5 aerial kilometer south-southwest of Lake Leonard.^[2]

Leonard Kniaseff is one of the active volcanoes in the Philippines, part of the Pacific ring of fire.

Activity

The Leonard Kniaseff Volcano's area has been an object to a geothermal exploration program.^[3]

Manat thermal area is north of Lake Leonard, solfataras occur around its southwest rim, and active solfataras, fumaroles, and hot springs are found in the Amacan-Gopod thermal area south of the lake.^{[citation needed]}

There was a scare in 1995 but PHIVOLCS' investigation at that time did not disclose any unusual activity, and no unusual activity has been reported since then.^{[citation needed]}

Its last eruption was dated as early as c. 120 AD.^[4]
