Which outcome occurs when a proglacial lake overfills?

💡 Explanation

Jökulhlaup flooding occurs because hydrostatic pressure causes basal ice sheet melt, which fills the proglacial lake beyond capacity; therefore, sudden release causes massive flooding, rather than rebound alone which works on longer timescales.
