Light ash fall was noticed in Tegalmulyo and Tlogowoatu villages, Klaten, Central Java, after Mount Merapi spewed lava toward Kali Gendol Sleman in Yogyakarta on Friday night.
Klaten Disaster Mitigation Agency head Bambang Giyanto said the ash fall occurred at around 9.30 p.m. and lasted for 20 minutes.
"Last night we noticed a thin ash fall in Tegalmulyo and Tlogowatu in Kemalang district," Bambang said, as reported by kompas.com on Saturday
The agency then headed to the two villages to distribute around 5,000 masks to the residents.
“Based on our monitoring, there is no rain from the ash anymore this morning. It only happened last night," Bambang said.
