Which risk increases significantly when low-silica lava erupts subglacially?

💡 Explanation

Jokulhaups risk increases due to increased melting of ice from the higher heat capacity during subglacial low-silica lava eruptions; the efficient conductive heat transfer mechanism rapidly melts ice because the lower viscosity lava permits broader contact, therefore causing larger, faster meltwater accumulations rather than localized steam plumes or cone formation.
