DENPASAR  Indonesia (Reuters) - Indonesia raised its warning for  Baliâs Mount Agung volcano  to the top level four alert on Monday  closed the holiday islandâs airport and told residents around the mountain to immediately evacuate  warning of an âimminentâ risk of a larger eruption.

Baliâs airport was closed for 24 hours from Monday morning  disrupting 445 flights and some 59 000 passengers  due to the eruption and the presence of volcanic ash from  Agung   but local officials said the closure could be extended.
âThe potential for a larger eruption is imminent â it said  referring to the visible glow of magma at Agungâs peak overnight.
Residents were warned to âimmediately evacuateâ a danger zone that circles Agung in a radius of 8-10 km (5-6 miles).
 Agung  rises majestically over eastern Bali to a height of just over 3 000 metres (9 800 feet). Eastern Bali is relatively undeveloped  with traditional rice paddies doting the landscape and the occasional budget resort  unlike the heavily populated southern tourist hub of Kuta-Seminyak-Nusa Dua.
 Agung âs last eruption in 1963 left more than 1 000 people dead and razed several villages.
Analysis suggested the threat should not be as great this time because âenergy at  Mount Agungâs  magma chamber is not as bigâ and with the ash column only around a quarter as high so far as the 20 km (12 miles) reached in 1963  said Sutopo.
Tourism business has slumped in Bali since September when  Agung âs volcanic tremors began to increase.

According to the Volcanic Ash Advisory Centre in nearby Darwin  Australia  there is âash confirmed on the ground at Denpasar Airportâ as well as ash at FL300 (which refers to flight level at 30 000 feet) in the vicinity of  the volcano .
Baliâs I Gusti Ngurah Rai airport  which is about 60 km (40 miles) from  the volcano   will be closed for 24 hours  according to its operator. A total of 445 flights - 196 international and 249 domestic - and 59 000 passengers had been affected.

The alert level on  Agung  had been raised to the maximum in September  but was lowered in October when seismic activity calmed. However  volcanologists now say the volcano has entered a new phase with magma now visible at  Agung âs peak  meaning a greater risk of a larger eruption.

Down the hill  past the town's plaza and up another hill   50-year-old Maria Rivera  watches  her  husband and two friends remove broken furniture and soggy sheets from their home  which was destroyed by the storm. It is 2 p.m.  and the three men toss the debris into a truck one of them owns. City officials never showed up to clear the debris  and crews with the U.S. Federal Emergency Management Agency did not come until this month to assess the damage.
Tears moisten  Rivera 's eyes as  she  gazes at what remains of the home where  she  lived for 19 years with  her  husband and three children.
"I haven't been able to assimilate everything that has happened "  she  says  adding that  she  spends most of the day bracing for darkness. "When night falls  you start growing anxious  depressed. Everything has changed ... Sometimes I go to places that have power and I tell my husband  'I don't want to go back.'"
By 4 p.m.  some generators in  Rivera 's neighborhood start rumbling as darkness approaches on the shortest day of the year. A teenager bounces a basketball and takes a couple of shots on a court before heading home  while several men wrap up reconstruction efforts at a roofless home that federal crews fitted with a blue tarp just two weeks ago.
