- Аннотация: Debris flow activity in the Geysernaya River basin was mapped. Large-scale debris flow processesdue to the collapse of fragments of the valley’s left wall were observed in this area three times over the past 40years. Three independent debris flow areas of the river basin were identified and described: the upper reachesof the river, the Levaya Geysernaya basin; the middle reaches of the river, below the dammed lake that formedin 2014; and the lower downstream part, below the dammed lake that existed in 2007–2014. Debris flow processesare typical of most tributaries of the Geysernaya River. Moreover, debris flows can be aseasonal in theleft tributaries, because they are formed under constant heating and active gas–hydrothermal influencewithin the thermal fields. The landslide dam formed in 2014 is resistant to erosion, and an independent outburstof the dammed lake is unlikely. With further erosion of the 2007 dam and expansion of the breach in thedam body, collapse of its sides and debris flow in the lower part of the Geysernaya River valley should not beruled out. Risks of rockfall, landslide, and debris flow processes, most likely on the left wall of the valley,should be taken into consideration in planning the development of recreation facilities.
