Which consequence results when tephra deposition on glaciers accelerates melting?

💡 Explanation

Glacial melting increases because tephra lowers surface albedo increasing solar radiation absorption via positive feedback; therefore, water accumulates and potentially breaches ice dams causing 'Jökulhlaups', rather than affecting volcanic explosivity.
