Which consequence results when wind redistribution of tephra deposits creates uneven ground saturation following a volcanic eruption on an Iceland glacier?

💡 Explanation

Jokulhaups occur when tephra distribution causes differential melting and subglacial lake formation; this is because hydroisostasy weakens ice dams, leading to catastrophic release of meltwater, therefore initiating flooding rather than ice formation.
