Satellite images reveal Bali's two volcanoes are CONNECTED and share the same "plumbing system" despite being more than ten miles apart (and it could explain the devastating outbreak that killed 1,600 people in 1963 )
- Bali's Agung volcano eruption in 2017 forces the evacuation of 100.00 people
- Satellite images from ESA showed a bubble of magma three miles away
- This suggests that the magma chamber plumbing is associated with nearby volcano Batur
- Two eruptions in short time in 1963 saw more than 1,600 people die
Satellite images reveal plumbing from Bali's Agung volcano can be connected by its neighbor Mount Batur, 18 km away.
Scientists studied the volcano as it awoke from a 50-year sleep and spit ash into the atmosphere for several weeks at the end of 2017.
Images from the European Space Agency revealed an unusual underground bubble four inches (10 cm) in height on the northern flank of the volcano, more than three miles (5 km) from the summit.
This expert's claim shows that the mountain magma can move horizontally as well as vertically, indicating that it is physically connected to Mount Batur.

Satellite images reveal plumbing of Bali & # 39; The Agung volcano can be connected with its neighbor, Mount Batur, located 11 miles (18 km) away. Images from the European Space Agency revealed an unusual underground bubble of four inches on the northern flank of the volcano, more than three miles from the summit, seen in green as a circular pattern to the right of Angung's bottom
A team of scientists led by the University of Bristol, used satellite technology from ESA to look at any superficial fluctuations during the volcanic activity in 2017.
During this period, experts from the University School of Education used Sentinel-1 satellite images from ESA to monitor the basic deformation of Agung.
They say their results could have important implications for forecasts of future outbreaks in the area.
Dr. Fabien Albino of the University of Bristol's Schools School Library, the main author of the paper, said: "Surprisingly, we noted that both the earthquake activity and the earth deformation signal were located five kilometers away from the summit, meaning that magma must move sideways and vertically upwards.
& # 39; Our study gives the first geophysical evidence that Agung and Batur volcanoes may have a connected plumbing system.
& # 39; This has important implications for outbreak forecasts and may explain the occurrence of simultaneous outbreaks, as in 1963
Scientists studied the volcano as it spewed ash for weeks in 2017 to uncover what caused it to break out 50 years of dorm. ESA satellite images showed a bubble of magma three miles away, indicating Batur and Agung are connected.
The activity of the volcano caused fear that it would violently erupt and cause destruction in the 1963 event, which saw 1,600 people lost their living. The event more than 50 years ago was almost immediately followed by a minor outbreak of its neighbor to the northwest
HOW CAN RESEARCHERS PROVIDE VOLCANIC ERUPTIONS?
According to Eric Dunham, an associate professor at Stanford University's School of Earth, Energy and Environmental Sciences, & # 39; Volcanoes are complicated and there are currently no universally applicable means of predicting outbreaks. It will probably never be. "
However, there are indicators of increased volcanic activity that scientists can use to predict volcanic eruptions.
Scientists can track indicators such as:
- Volcanic infrasound : When the lava lake rises in the crater of an open ventilation volcano, a sign of a potential eruption, pitch or frequency of the sounds generated by the magazine tends to increase
- Seismic activity : Prior to an outbreak, seismic activity in the form of small earthquakes increases and almost always shake as magma moves through the "volcano's" plumbing system.
- Gas emissions : As magma approaches the surface and the pressure drops, gases emerge, sulfur dioxide is one of the major components of volcanic gases, and rising amounts are indicative of increasing amounts of magma near the surface of a volcano. is caused by magma, gas or other liquids (usually water) underground or by movements in the Earth's crust due to movement along fault lines. Swelling of a volcano cans signal that magma has accumulated near the surface.

Authorities issued a warning to residents in November 2017 and forced more than 100,000 people to evacuate their homes.
This was after an increase in the number of small earthquakes around the volcano was discovered two months before its main eruption.
The activity of the volcano caused fear that it would violently break out and cause destruction in the 1963 event, which saw more than 1,600 people lose their lives.
The outbreak of 1963 was among the deadliest volcanic eruptions of the 20th century, so scientists discontinued the opportunity to monitor and understand its revival.
The event more than 50 years ago was almost immediately followed by a minor outbreak of its neighbor to the northwest, where the fuel speculation of the two volcanoes was connected.
Experts now believe that they have found the first "geophysical evidence" that this is true.
Dr. Juliet Biggs, who led the satellite study, added: "From remote counting we can map any soil movement, which can be an indicator that fresh magma is moving under the volcano."
