摘要

本文研究了1977年乌苏双火山活动引起的托雅温泉温度、水位和化学成分的变化。以下是1978年得到的结果。在最初爆发之后的一系列潜水式爆发中，所调查的温泉温度逐渐升高。在温度相对较高的地区，它们的水位或多或少有所上升。根据水体化学成分的变化，托雅地区的温泉可分为两类;一种是氯离子浓度升高，水温升高;另一种是碳酸氢盐含量增加而pH值降低。

The Influence of the Activity of the Usu Volcano in 1977 on the Toya Hot Springs, Hokkaido

Variations in temperature, water level and chemical composition of the Toya hot springs due to the activity of the Usu double volcano in 1977 were investigated. Following results were obtained in 1978.
Temperatures of hot springs investigated increased gradually during a series of the phreatic explosions that followed on the initial explosions.
The water level of them rised more or less in the area keeped relatively high temperature.
By the variation of chemical composition in water, the hot springs in the Toya area can be divided into two groups ; one is characterized by the increase in both chloride concentration and water temperature ; the othes by the increase in bicarbonate content but the decrease in pH.
