For America and Europe, the fear of Iceland's volcanoes dates back to the 2010 eruption of the unnameable Eyjafjallajökull, which released a cloud of ash that paralyzed passengers on more than 20,000 flights, which meant a million-dollar loss.
Will something similar happen with the Bardarbunga? This was analyzed by some geologists after Icelandic seismographs recorded two earthquakes measuring 4.7 on the Richter scale on October 26 and 27.
Bárðarbunga is an active volcano layer located under the ice sheet of the Vatnajökull glacier, the largest in Iceland. It rises to about 2,000 meters above sea level, making it the second highest mountain in Iceland, only about 10 m below Hvannadalshnjúkur. It is part of a volcanic system 200 km long and 25 km wide. The last time it erupted was in 1910. However, in August 2014, the volcano began to show signs of increasing seismic activity, which forced the Icelandic aeronautical authorities to issue various alerts. Its eruptions came to alter the weather and air traffic in the northern hemisphere of the Earth.
The following video shows its extraordinary last eruption in 2014:
The strong earthquakes were confirmed by the United States Geophysical Service (USGS) which registered them - each one - at 4.6 on the Richter scale.
Pall Einarssonn, from the University of Iceland, told Visir.is that the earthquakes on October 26 and 27 were the most intense since 2015.
"There was nothing like it until tonight," Einarssonn said. “It just shows that this process is in full swing (…) Bárdarbunga is preparing for the next episode of this sequel and it can be in several ways. It is a very versatile volcano, "he added.
According to Pall Einarssonn, it is not known when, but "it is clear that Bardarbunga is preparing for the next eruption (...) The important thing is to be vigilant".
Among the dangers Einarssonn points out is the flow of lava into the Veiðivötn region, which can affect the country's electricity production. What is expelled can also cover vast areas of fishing. In turn, the lava in the direction of Veiðivatna is also worrying.
Bardarbunda is not the same as Eyjafjallajökull, and forecasts of a possible eruption do not necessarily include chaos for flights to and from Europe over the Atlantic, which is reassuring.
The volcanic system is hidden under the ice, and is 200 kilometers long and 25 wide. Its height is 2009 meters above sea level, and its activity places it among the most important of the 130 volcanoes in the country. In 1477 it registered a powerful eruption of level 8 on the international scale.
