The article presents the results of researches of thermal waters of South-Eastern solfataric field of Ushishir volcano (Yankicha Island, Central Kurile Islands) in 2007 and 2015. Detailed studies of the physicochemical properties of the hydrothermal springs of the volcano were begun in 1950-60 years. Modern studies have confirmed the stability of physical and chemical parameters of hydrotherms. Modern thermal waters (temperature up to 100 °C), as before, can be attributed to acidic (pH 2.8-3.6), highly mineralized (TDS 23-36 g/l), sodium chloride. The chemical composition and ratio of the main macroelements of hydrotherms are close to the sea waters of the region. The uniqueness of these waters distinguishing them from other coastal hydrotherms of the Kuril Islands is their high acidity. The increased content of balneological elements (Br – 107 mg/l; B – 36 mg/l; I – 0.5 mg/l) in hydrotherms determines their high therapeutic value, which allows them to be used in the treatment and prevention of a wide range of diseases.
