Which outcome occurs when thick tephra deposits accumulate?

💡 Explanation

Increased crustal loading and subsidence appear because the isostatic depression mechanism causes downward displacement due to the immense weight of rapidly deposited tephra; therefore subsidence happens, rather than uplift induced by magma removal.
