Mount Agung in Bali is experiencing unprecedented levels of seismic activity and could erupt in a matter of hours if tremors continue, Indonesias volcanology centre has said.
More than 75,000 people have been evacuated in the last few days as Agung, the highest point of the island, has experienced hundreds of internal volcanic earthquakes.
Instrumentally we have never recorded such high energy or seismicity from Mount Agung, Devy Kamil Syahbana, a seismologist from Indonesias centre for volcanology and geological hazard mitigation, told the Guardian.
Data showed that Mount Agung experienced 844 volcanic earthquakes on Monday, and 300 to 400 earthquakes by midday on Tuesday, he said. We need to pay attention because these kinds of earthquakes indicate the movement of magma and increase the probability of an eruption.
Evacuated people have sought shelter in hundreds of village halls and sports centres and in the homes of relatives in more than nine districts. President Joko Widodo is scheduled to visit evacuees at several camps on Tuesday.
Authorities have urged people to stay out the danger zone, a designated five- to seven-mile radius of the volcano.
The increasing frequency of deep and shallow volcanic earthquakes, as well as local tectonic tremors, is an indication that magma continues to move toward the surface. The alert status of Agung was raised to the highest level on Friday evening following a significant spike in seismic activity.
Kasbani, the head of the volcanology centre, told local media that if tremors continued, an eruption the first in more than half a century could be a matter of hours away.
The volcanology agency is also drawing data from GPS and satellite imagery, including a thermal camera. Readings from these measurements are in line with the increase in volcanic tremors.
Syahbana said it was impossible to say that Agung would definitely erupt, only that the data showed there was an increasing probability that it would.
There is no volcanologist in the world who could predict precisely when a volcano will erupt, he said. Volcanoes are a stochastic system, many complexities are unknown by the human brain and technology.
Mount Agung last erupted in 1963, when more than 1,000 people were killed. That event was preceded by an increased frequency in earthquakes.
One of the difficulties in predicting the likelihood and timing of an eruption on Agung is that monitoring of the volcano began only after the 1963 eruption.
Other volcanoes in Indonesia that have erupted more recently offer a greater wealth of data for seismologists to compare and assess.
But for Agung we have no instrumental documentation, said Syahbana. The only records that we have is of the phenomena that were observed and reported by people around the volcano prior to the 1963 eruption.
Balis Ngurah Rai international airport, which is about 47 miles from the volcano, remains open, with flights running as normal on Tuesday.
In the event of an eruption and ash clouds that could disrupt air travel, authorities have made preparations for flights to be diverted to seven regional airports, including on Java and Lombok islands.
The UK, Australia and the US are among several countries that have issued travel advisories in recent days, warning that volcanic activity on Agung could interfere with travel plans.
Mount Agung is one of many active volcanoes in the ring of fire, a string of volcanoes and seismic activity that runs through the Indonesian archipelago and the edges of the Pacific Ocean.
James Wilson, 28 from Bristol, is staying near Mount Agung with his fiancé and they have plans to climb the nearby Mount Batur on Wednesday morning. He said: Its always been our plan to come to Bali and go up Mount Batur so were quite keen to continue if we can.
Wilson, who is staying in the Volcano Terrace Bali hotel around 10km from Agung, said there are mixed feelings in the local community. He said: Some people are quite relaxed and others are quite worried because of the evacuations. We did see smoke this morning above Agung though, and our hotel shook a bit earlier in what I assume was a tremor.
Im not sure why we havent been evacuated. In some respects it might be foolhardy to stay and in another we want to get on with our holiday as much as we can.
It’s God’s punishment on the world for allowing Trump to become president.
global warming
I don’t want to blame macaroni.
I like macaroni....especially with some ketchup.
Well that’s good because I wouldn’t want to be somewhere where I ain’t there.
good grief, nearly every place I wanted to visit is systematically being destroyed or made unvisitable :(
Tell me that you’re joking about putting ketchup on macaroni.
Ugh !
.
We’re living on an atomic bomb?
That explains why my radio don’t work.
An earth EMP.
That or the batteries are dead.
I think it would be wise for Trump to draft his predecessor to head over to give us his personal perspective on the subject given he has local knowledge of the area. Put him right at the apex of the cone.
I’ve heard the theory that the tidal action of a close moon causes the earth’s core to remain molten. Now why that didn’t work for the moon, I don’t know.
I am happy it’s there.
Just the other day I had a “We’re Living On A Nuclear Bomb Party!!!”
You shoulda seen the fireworks!
I guess so.
We’re all riding a nuclear bomb!
And there ain’t any seat belts!
It’s an acquired taste that only the finest cultured palates can appreciate.
Sort of like snails for poor people.
I thought slugs were snails for poor people.
Ice Ages and Volcanic eruptions seem to statistically occur together. It could simply be because a massive volcanic eruption can trigger the ice age. Or perhaps the same physical phenomenon that trigger ice ages can also trigger volcanic eruptions. At any rate, we know for a fact that Climate Change Scientists are clueless.
Why is it that whenever we try to have a discussion on FR about the finer things in life, somebody always has to bring up slugs?
Slugs will never be fine dining because when you season them with a little salt, they disappear.
Myself, I would use only pepper.
No, you use that on grizzly bear.
Because it is hollow.
Please add Hollywood, San Francisco and Washington DC to your itinerary...;)
