In late September the lake had cooled to around 12 °C marking the low point of the cycle. Since mid-October the lake has been warming slowly and has now reached 22 °C.
Chemical analysis of lake water collected on 9 October showed no significant changes in the makeup of the lake waters since the previous sample collected on 9 August. The pH remains at 0.8, having ranged between 0.7 and 0.9 over the last 6 years. Other key chemical indicators such as the respective water concentrations in Mg (magnesium) and Cl (chloride) can be used to track whether the uprising fluids travel through new fractures or in the proximity of magma.
