Increasing conductivity in Skeiðará glacier river (Grímsfjall volcano)

Since 20-January-2014 there has been increase in conductivity in Skeiðará glacier river that comes from Vatnajökull glacier. The reason for this change is that water is leaking from Grímsfjall volcano. Water levels have also been increasing and dropping during this time since this started.

Conductivity is now measured at 416 µS/cm and according to Icelandic Meteorological Office that is an high value coming from Grímsfjall volcano. This water also goes trough several lakes and before it reaches the sensor at Gígjukvísl bride. So at the source of Skeiðará glacier river this value is probably even higher. No major earthquake activity and no harmonic tremor activity has taken place following this water leak from Grímsvötnum glacier lakes. But it appears that some glacier quakes might be taking place at the moment. Such activity can be seen here on IMO website. Currently the volume of water in Grímsvötn glacier lakes is small since the eruption that took place in Grímsfjall volcano in the year 2011. Coverage of that eruption can be found here. At current time nothing more is expected to happen.
