COPENHAGEN. After an intense week of movements seismic constants in Icelandactivity remains stable near Grindavikthe most affected city, however, meteorological authorities continue to consider a high probability of a volcanic eruption due to the constant increase in the level of lava towards the earth’s crust.
Experts from the Iceland Meteorological Office (IMO) are closely monitoring how the flow of the magma below the surface, as well as increased levels of sulfur dioxide (SO2) in the atmosphere of the last few days.

For her part, the director of the IMO night surveillance center, Kristín Jónsdóttir, announced yesterday in a meeting with the Civil defense, that recent seismic activity caused the magma It would rise towards the Earth’s crust, which is already fractured and would not require greater effort to reach the surface, reported the local newspaper Iceland Monitor.
The Icelandic official confirmed that the seismic activity has decreased, as has the movement of the lava, so the telluric movements are less numerous and of lower intensity.
“He magma tunnel “It continues to widen and deepen, but it widens and deepens less in the last 24 hours than in the previous 24 hours,” Jónsdóttir reported.
He insisted that “we still believe that there is still a possibility that there is a rash. In the last eruptions we saw that it is precisely when that movement (of the magma) begins to reduce that the moment of rash “It’s getting closer,” he told Icelandic public television RUV.
“While model calculations still indicate that the magma is flowing into the vent, it should be considered likely to enter rash and that this increased probability will last at least the next few days,” he commented for Iceland Monitor.
The data also indicate that the further expansion of the magma occurs west of Hagafell. Therefore, scientists believe that this area, which is the center of the activity, is the most likely source of Volcanic eruptions.
“The consequences of a rash of this type depend on their size and are difficult to predict,” said Kristín.
According to her, the exact recording location is a prerequisite to be able to predict lava flows.
“But if lava arises in the area in question, it can flow towards Svartsengi, Grindavikbut also towards the north and east, depending on where exactly the lava comes out.”
The police have this week allowed the controlled entry of residents so that they can collect their belongings in the city of Grindavík, evacuated a week ago when the outbreak began. seismic activity and caused the government to declare a state of emergency.

Construction work could last between 30 and 40 days, according to the Icelandic digital media Visir. Benedikt Ófeigssonanother IMO official had indicated that it is likely that the magma under Grindavík has come very close to the surface, possibly about 500 meters, and he stated that the increase in SO2 levels in the atmosphere is proof of its proximity.
“SO2 is not released from magma until very close to the surface. Only in the upper kilometer,” he said, quoted by RUV.
Iceland is a volcanic island Located in the North Atlantic, it has a population of about 370 thousand inhabitants and an area of more than 100 thousand square kilometers.
