While hiking, which risk increases with substantial pyroclastic material cover near a recently active volcanic caldera?

💡 Explanation

Lahars become more likely because saturated pyroclastic flows readily mobilize into mudflows; this process is bulked by rainfall. Therefore, lahars are the increased risk involved, rather than seismic activity which indicates underground adjustments.

• Which outcome follows increased rainfall intensity on soils?
• Which consequence results when coastal dunes migrate inland onto wetlands?
• Which hydrogeological consequence results when concentrated animal feeding operations (CAFOs) increase?
• Which consequence results when prolonged river sediment deposition exceeds compaction?
• What height reduction occurs behind newly constructed artificial levees?
• Which outcome occurs as transverse dune migration slows at desert margins?
