Which outcome occurs when heavy tephra accumulation collapses vegetation?

💡 Explanation

Increased runoff occurs because vegetation collapse reduces soil binding, caused by raindrop impact and tephra weight. This vegetation weakens slope stability and reduces infiltration. Therefore, more surface water runs off, rather than being absorbed, increasing discharge volume.
