Which risk increases when basaltic lava erupts underwater?

💡 Explanation

Hyaloclastite formation increases underwater because rapid cooling causes brittle fracturing and fragmentation of lava due to thermal stress; therefore, the answer is hyaloclastite formation rather than other lava features because those relate instead mostly to viscosity during subaerial eruptions.
