Powerful earthquake swarm in Bárðarbunga
An earthquake swarm began in Bárðarbunga at seven o'clock this morning, and the largest earthquake, magnitude 4.5, was measured at 6:29 am.
In the early morning, three earthquakes were measured above magnitude 3, when 40 earthquakes have been measured. A statement from the Icelandic Meteorological Office says that the swarm is in the northwestern caldera and is considered quite unusual.
Up to 20 earthquakes above magnitude 3
The intensity of the earthquake swarm in Bárðarbunga decreased significantly at around 9 o'clock this morning; few earthquakes have been measured since then.
Despite the reduced activity, earthquakes are still being measured and ongoing developments will be closely monitored, according to the statement from the Icelandic Meteorological Office.
The earthquake swarm began just after 6 am this morning and peaked at 8.05 am when the largest earthquake, magnitude 5.1, struck.
Seventeen above magnitude three
In addition, seventeen earthquakes above magnitude three have been recorded today, two of which were at or above magnitude 4.
It is noted that the flight color code over the volcano remains yellow, indicating increased activity compared to normal conditions and uncertainty about the development. can be spread that way.”
Not linked to Grímsvötn lakes
There is no connection between the powerful earthquake swarm that began in Bárðarbunga this morning and the flash flood that began in Grímsvötn lakes yesterday.
This is what Magnús Tumi Guðmundsson, professor of geophysics at the University of Iceland, says in an interview with mbl.is.
Bárðarbunga and Grímsvötn lakes are two of the seven main volcanoes under Vatnajökull glacier.
