At the foot of Indonesia's Mount Semeru, what is left of the houses along the main village road are covered in a thick layer of hardened volcanic ash.

Curah Kobokan was among the worst-hit areas when the 3,676-metre (12,060 ft) Mount Semeru erupted on Saturday, sending a cloud of ash into the sky and dangerous pyroclastic flows into villages below.

At least 34 people were killed and 22 people were missing as of Tuesday.
