After Mount Agung emitted a thick plume of smoke reaching (4, 000m), airlines have been issued a ”red warning” about the danger of volcanic ash in the skies close to Bali.
The eruption of the volcano on the Indonesian island makes around 2,000 passengers stop at Bali airport.
More than 25 flights have been disrupted, because that is the second major emission from the Indonesian island volcano this week
Mount Agung had shown signs of activity three days in this week.
Buildings, roads and cars were covered by the ash, while magma – molten rock – has now been detected close to the volcano’s surface.
“The activity of Mount Agung has entered the magmatic eruption phase”,officials said.
“It is still spewing ash at the moment, but we need to monitor and be cautious over the possibility of a strong, explosive eruption”, they said.
Mount Agung erupted in 1963 that was the last time, and more than 1,000 people died.
Indonesia is home to more than 130 active volcanoes; it sits on so-called Pacific Ring and has volcanoes – more than any other country.
On Sumatra Island there is Mount Sinabung which has been active since 2013 and is currently at its highest alert level
A senior volcanologist: ”we will continue to see eruptions like this on similar scales, but we cannot predict when Mount Agung will really erupt.
The holiday island lost about $110000000 (£83000000) in tourism and productivity during the major evacuation, according to official estimates.
