| Sumario: | The mass balance of El Chichón crater lake is controlled by precipitations, evaporation and seepage through the lake bottom.The main non-meteoric source of water and Cl for the lake is a boiling spring (Soap Pool) discharging saline and neutralwater with a variable flow rate from 0 to 30 kg/s inside the El Chichón crater. Variations in lake volume over time were approximatelydetermined from digitized photographic views of the lake using an empirical relationship between depth of the lake andsurface area, obtained after four bathymetric surveys. The best correlation between the observed changes in lake volume, Clcontent and the measured flow rate of Soap Pool was obtained by a box-model for the Cl mass balance. Based on a trend in the Clcontent of the Soap Pool water a model of a buried initial crater lake is proposed. |
