Earthquake Hazard in Denmark

Publikation: Bog/rapportRapport (offentligt tilgængelig)

Abstrakt

This report provides the seismic hazard map of Denmark compiled by GEUS for the purposes of seismic zoning within the Eurocode 8 context. It was commissioned to assist the drafting of the Danish National Annexes to Eurocode 8. Eurocode 8 is the European Union building standard for design of structures for earthquake resistance. The geology and seismicity is very diverse across Europe, and it is necessary for each country to carry out their own analysis based on local conditions.
The values are intended to give a general indication of the expected hazard level. The map in figure 16 is provided with a return period of 475 years, showing the peak ground acceleration (PGA) for rock site conditions. Values were computed over an area bounded by 53deg.N – 59deg.N and 4deg.E – 18deg. E. The analysis is only carried out for on-shore conditions and the calculations should be re-evaluated after 10 years due to increasing uncertainty; ultimo 2024.
Seismic hazard in Denmark is low with respect to many other parts of the world, but the historical records do tell of earthquakes with large impact e.g. in 1759:

“...To the west of the Kattegat in Aalborg an upper storey of St. Bochs or Budolphi church fell down. This caused great damage to an extension of the building and the collapse of the two ends of the church which were only restored in 1764. Elsewhere in the town arches were cracked and several buildings moved on their "ground wall" foundations...”
