Which consequence results when volcanic tephra accumulates rapidly?

💡 Explanation

Increased lahar formation will occur because heavy tephra accumulation saturates soil, triggering debris flows; therefore, landslides are more frequent because the increased weight destabilizes slopes, rather than stabilizing seismic activity.
