Week overview -

Earthquake activity throughout the country is described in a weekly summary that is written by a Natural Hazard Specialist. The weekly summary is published on the web every Tuesday. It covers the activity of the previous week in all seismic areas and volcanic systems in the country. If earthquake swarms are ongoing or significant events such as larger earthquakes have occurred during the week, they are specifically discussed. More

Remarks of a specialist

Water level in rivers are expected severely rise in all of Iceland tomorrow, Wednesday, especially in the S-part, SE- part and the East-part.

The electrical conductivity in Múlakvísl has decreased significantly and no gas has been measured near Láguhvolar.

Due to malfunction we have turned off the service publishing hydrological data on the map. Instead see the data using our Rauntímavöktunarkerfi.
