Since nine o'clock last night there have been over 1200 earthquakes detected. Nine of those have been more than 3M and the biggest of those was last night just before 2:30AM. The last one of those was detected at 6:46 AM and it was 3.2M.
The Natural Disaster Expert with the Met Office, Hulda Rós Helgadóttir, told mbl.is about this and adds that the seismic activity looks like it is going down, compared to last night.
"There is still some activity but after the earthquake just before 2:30 this morning, it has slowed down. There are still earthquakes, but none as big as that one," she says.
Some of the earthquakes have their source southwest of the mountain Keilir on the Reykjanes peninsula. mbl.is/Kristinn Magnússon
Magma moving in conduits the culprit
"Before these series of earthquakes started this weekend we had a few hundred earthquakes per week. Now we have been detecting a few thousand earthquakes per week," she says.
"The earthquakes close to Kleifarvatn are considered earth tremors. The magma moving in conduits by Fagradalsfjall are changing the tension in the Reykjanes peninsula resulting in earthquakes in other areas on the peninsula.
She says that subsequently there is probably no magma by Kleifarvatn causing those earthquakes, but the culprit is the magma moving near Fagradalsfjall.
