Java volcano: Reactions from Kediri to Bandung
The Indonesian island of Java has been showered with ash and detritus from an eruption of the Mount Kelud volcano, toward the east of Java, last night.
BBC News website readers have been telling us how the regions of Java have been affected, from Kediri, the nearest town to the volcano, to Bandung, Indonesia's third-largest city.

"I'm living in Kediri, the nearest town to the volcano. I was at home when the eruption happened. It was about 23:30 and I heard what I thought was thunder and rain coming down.
"There was thunder and lightning, but it was raining sand, not water. It was quite strange seeing it raining sand.
"Today everything is a light grey colour and sand is just everywhere, on the roof, on the road, in the trees, and it's getting inside our house too.
"Generally the reaction here has been surprise. Sand is being swept off roofs; people are throwing water to clear the road in front of their homes and businesses.
"Around town there has quite a bit of damage. Some shop fronts collapsing under the weight of the sand. Most shops have been closed today as people clean up and clear their roof in case more sand and ash comes.
"Traffic has been quite light as most people stay at home away from work.
"I haven't seen public services helping with the cleaning but there have been a lot of police vehicles driving on my street.
"Another eruption alert has been issued for tonight. I don't know if there are any plans in place, but people aren't expecting a second eruption as there has been an announcement stating that seismic activity has declined."

"Last night, around 22:15, Mount Kelud erupted. The electricity has been bad since.
"This morning as I woke up, everything was white around me; my house gate, the grass and the pavement to my house.
"At 05:00, my mum went for a walk; when she came back, she was covered in dust. Everything is covered in thick ash.
"Lots of flights - about 350 - have been cancelled.
"Just now we had a rain shower, which was quite good.
"The emergency services are giving more advice; they have traffic police out. They are expecting a bigger eruption, but we don't know when."

"I haven't come out of my home. My surroundings are covered in thick ash.
"Last night I had problems sleeping as I heard some faint thumps and felt some tremors.
"I had heard that Mount Kelud in east Java had been quite active recently. Knowing it was around 242km (150 miles) from Yogyakarta, the city I live in, I was not worried. But when I woke up, all I saw outside my window was a monochromatic view in greyish hues. Mount Kelud had showered Yogya with ashes.
"This morning the ash was still drizzling. I could also feel that my bedroom floor was sandy.
"The authorities had suggested that people should wear a mask, eye protection, and a rain coat when they go out.
"Schools and universities were cancelled, shops were closed. It felt a bit like a dead city for a while.
"As a student who cannot cook and lives away from family, this is quite a personal disaster. I thought: 'Where do I get food? My drinking water was finished last night!'
"This is not the first time I experienced an ash shower. Back in 2010, when Mount Merapi, just north of Yogya, erupted, the city looked the same.
"I just hope it will rain soon to wipe the ashy layer off our beloved city's face.
"My thoughts are with those who are the direct victims of this eruption."
