对塔尔火山口湖的水化学研究和回声探测调查为了解其化学和物理动力学提供了新的见解。在2010年4月至2011年6月的火山地震动荡期间，塔尔火山口湖的沃茨显示出化学成分的变化，以及与地震动荡相关的二氧化碳排放量的增加。化学和同位素数据表明，湖水有海水和大气降水的贡献，并在强烈的火山-地震动荡时期接受深层热液水和气体的注入。这些膨胀期可能会导致断层的不透水盖层通常密封更深的Taal热液储层在下面的Taal岩浆房的脱气和对流运动。
Studies of the water chemistry of Taal crater lake and echo-sounding surveys have provided new insights into its chemical and physical dynamics. During the volcano-seismic unrest of April 2010–June 2011, the waters of Taal crater lake showed changes in chemical composition and increases in CO 2 emissions associated with the seismic unrest. The chemical and isotopic data show that the lake water has contributions from both seawater and meteoric water and receives injections of deep hydrothermal water and gases during periods of intense volcano-seismic unrest. These inflationary periods may lead to faulting of the impermeable cap rock that usually seals the deeper Taal hydrothermal reservoir in response to degassing and convective movements in the underlying Taal magma chamber.
