Deep earthquakes in Bárðarbunga volcano system and increased conductivity in Jökulsá á fjöllum glacier river

Today (7-November-2017) there has been deep earthquakes taking place in Bárðarbunga volcano system, just south-east of the main volcano. This earthquakes are not strong and only have the magnitude of 16,4 to 18,8 km. This time none of the earthquakes that happened reached magnitude 1,0.

Location of the deep earthquakes is south-east of the main Bárðarbunga volcano. It is marked by three red dots. Copyright of this image belongs to Icelandic Met Office.

It is also in the news that conductivity in Jökulsá á fjöllum glacier river (map of Jökulsá á fjöllum glacier river can be found here) is at all times high and have been increasing for the last two weeks (14 days) and are now the highest ever recorded. It is unclear at the moment why this is happening as no eruption has been detected from Bárðarbunga volcano during this time. The glacier river is also unusually dark for this time of the year and smell of hydrothermal water has also been detected. Current values are 295µ/cm. This is a risky situation if something more happens under the glacier as this area goes close to Road 1 and connected bridges. If a major flood happens those bridges are going to get lost and there is always a risk of more damage happening, but that depends on factors that are impossible to predict.

Update 1

There is a possibility that this might be a glacier flood from Kverkfjöll volcano. That has not been confirmed as of this moment. Glacier flood from Kverkfjöll volcano happen every few years.
