Which risk increases on steep volcanic slopes with substantial pyroclastic deposits?

💡 Explanation

An unstable accumulation of pyroclastic material increases failure by gravitational unloading; therefore debris avalanches develop, because rapid sediment relocation leads to landslides, rather than changes in geothermal gradient or magma composition, or flow type.
