All from Iceland Monitor:
Last night an earthquake of the magnitude 4.3 was detected in the southern part of the Bárðarbunga caldera followed by several aftershocks. No signs of volcanic eruption says the Iceland Met Office.
The smaller aftershocks measured between 2.4 and 2.5.
Bárðarbunga last erupted for six months in 2014- 2015.
Strongest earthquake in three years
An earthquake of magnitude 4,9 on the Richter scale was measured on the north side of the caldera Bárðarbunguaskja at 7.24 pm last night. The quake is the stongest one to be measured since the volcanic eruption in the lava field Holuhraun ceased on February 28th, 2015. The eruption had been ongoing since August 31st, 2014.
Bjarki Kaldalóns Fries, specialist of natural disasters at the Icelandic Meteorological Office, said to mbl.is. "On October 27th last year we measured two earth quakes, each of magnitude 4,7, and they were at the time the stongest ones that had been measured in Bárðarbunguaskja since the end of the eruption".
Kaldalóns Fries says they are monotoring the area even though it's unlikely there will be another eruption.
Earlier last night three earth quakes were measured on the north-east side of Bárðarbunga, of magnitude 3,7, 2,9 og 3,8 on the Richter scale. Around 20-30 afterquakes have been measured in the area since the spate began right before 6 pm last night.
