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

Considerable precipitaiton is forecasted in South and West Iceland, especially in the southeast part today. Increased run-off is expected in rivers in Southeast Iceland and rivers draining Mýrdalsjökull glacier.

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

HARMONIE - numerical weather prediction model

HARMONIE is a numerical weather prediction model (NWP) that is non-hydrostatic and convection-permitting. It is operated at 2.5 km horizontal resolution over a domain that covers Iceland and the surrounding seas. At this resolution it is possible to simulate explicitly some processes that are important for clouds and precipitation as well as meteorological phenomena related to up- and downdrafts. In order to simulate the interaction between the atmosphere and the surface, the model takes into account different types of land surface as well as processes in and at the surface.
