Abstract: Debris‐flow activity has been studied on talus slopes of the High Tatra Mountains since 1975. Both geomorphological experiments on slopes and sedimentological studies on lake sediments make it possible to distinguish calm periods and extreme event periods. The Little Ice Age was characterized by talus slope instability due to debris flows. During the last 15 years rapid reworking of sediments is explained by rainfalls of higher magnitude being more frequent during this period. © 1997 John Wiley & Sons, Ltd. L'activité des coulées de débris a été étudiée depuis 1975 sur des pentes des Hautes Tatras. Des expériences réalisées sur des pentes ainsi que des études sédimentologiques portant sur des sédiments lacustres ont permis de distinguer des périodes de calme et des périodes d'activité extrême. Le Petit Age Glaciaire a été caractérisé par une instabilité des pentes qui subissaient grandement l'action de coulées de débris. Pendant les dernières quinze années, le remaniement rapide des sédiments est expliqué par une fréquence accrue des pluies importantes. © 1997 John Wiley & Sons, Ltd.
