Bali’s largest volcano Mount Agung has been under the maximum volcanic alert since September 22 and scientists believe an eruption could be imminent.
Volcanologist Dr Janine Kripper, who has been monitoring Agung’s developments closely, said increased seismic activity makes an eruption “more likely than not”.
She tweeted: “There is still no more certainty with the Agung situation.
“As of the last report it is still more likely than not that an eruption will occur, but there is no certainty with this.”
However, in an ominous sign for Bali residents, Agung’s latest seismic activity graph shows a dramatic spike in volcanic movement.
The chart shows Mount Agung was hit by 931 earthquakes on October 12, the second largest amount since the volcano warning was increased.
The graph also shows that yesterday was the first time non-harmonic tremors were recorded under the Bali volcano.
A spokesperson for Bali’s Disaster Mitigation Agency explained that non-harmonic tremors are earthquakes that occur at least three times in quick succession, lasting between 80 and 140 seconds.

This latest graph comes after more than three weeks of dangerously high levels of movement within Mount Agung.
Earlier this month, MAGMA Indonesia said: “On average, there are still 1-3 earthquakes per minute with the total number reaching greater than 600 per day.”
Despite the looming threat of Mount Agung’s likely eruption, Bali officials insist that the island is still safe for travel.

Dewa Gede Ngurah Byomantara, head of Bali’s tourism board, said: “According to information from the National Disaster Mitigation Agency, 98 percent of the tourist areas remain safe in Bali, even if Mount Agung erupts.”
Mount Agung has not erupted since 1963 when a string of deadly explosions killed more than 1,100 people.
Bali Governor Made Mangku Pastika has “guaranteed” that their will be no deaths if Agung erupts again, because the 7.5-mile danger zone has been completely evacuated.
The UK Government has urged Brits in Bali to follow the advice of local authorities.
