Ash from a series of eruptions of Mount Merapi on the Indonesian island of Java has caused cancellations of flights to and from the capital, Jakarta.
The Indonesian government says the volcanic eruptions have killed 145 people since October 26th and forced more than 200,000 to evacuate their homes.
At least 47 flights of 15 airlines have been cancelled on Saturday and Sunday as volcanic ash has come close to Jakarta, more than 400 kilometers away from Merapi.
President Susilo Bambang Yudhoyono visited the nearby city of Yogyakarta on Saturday to oversee rescue operations.
Local media say Merapi's eruption is its biggest since 1872.
Observatory officials say they have no idea when the eruptions will end.
