In mid November 2010, Mount Bromo volcano began to erupt again. It was the first eruption since June 2004, and unlike most eruptions in recent decades, the eruption turned out to be long lasting. It started with ash emissions, and in increased in intensity in Dec. 2010 and Jan 2011, when huge amounts of ash prompted flight cancellations between and to Bali and Java. At the time of writing (end of Feb. 2011), the eruption is still going strong and it counts now as Bromo's biggest eruption recorded in history since official records began in 1804.
The eruption's has caused widespread damage due to near continuous ash fall, damaging buildings, roads, and destroying farmland. The most heavily affected areas NW of Bromo have been declared disaster areas by the Indonesian government.
