Which outcome occurs when snowpack rapidly melts along a fault during sudden tectonic movement?

💡 Explanation

A sudden earthquake can cause snow/ice melt, and result in increased lubrication of that fault through increased pore pressure and decreased shear stress (ice front retreat); therefore, glacial outburst floods are more prominent, rather than only seismicity, since melted water volume quickly increases.
