Which process creates caldera lakes after dome collapse?

💡 Explanation

Volcanic dome collapse leads to lowered land that accumulates significant rainfall & runoff; this concentrated flow establishes a drainage reversal mechanism. Because it erodes existing slopes inside the caldera, therefore drainage patterns shifts dramatically, rather than uplifting rock as in isostacy.
