A heavy rain in an ash-covered, mountainous volcanic region can lead to a lahar, which is a type of mudflow composed of volcanic ash and debris mixed with water. The precipitation can also act as a trigger for the lahar to occur, as it can loosen up the ash and cause it to flow down the slopes of the volcano. Slumps, rockslides, creep, and debris avalanches are not as likely to occur in this particular scenario.
