The Meaning of Eurocode 8 and Induced Seismicity for Earthquake Engineering in The Netherlands

The Netherlands is one of the few European countries where seismic loading is not a dominant part of the national codes. Only for very special structures, earthquakes are regarded as a separate loading case. Until now, Eurocode 8 (EC8) is not part of Dutch building laws nor is there an official Dutch translation. Tectonic seismicity mainly occurs in the southern part of The Netherlands. The Dutch code NEN 6702 has a zonation map which shows horizontal peak accelerations of 0.01g to 0.1g for a return period of 5000 years. However, this seismic zonation map is yet not coherent with the EC8 Natio... Mehr ...

The Netherlands is one of the few European countries where seismic loading is not a dominant part of the national codes. Only for very special structures, earthquakes are regarded as a separate loading case. Until now, Eurocode 8 (EC8) is not part of Dutch building laws nor is there an official Dutch translation. Tectonic seismicity mainly occurs in the southern part of The Netherlands. The Dutch code NEN 6702 has a zonation map which shows horizontal peak accelerations of 0.01g to 0.1g for a return period of 5000 years. However, this seismic zonation map is yet not coherent with the EC8 National Annexes for Belgium and Germany. Induced seismicity due to the exploitation of natural gas is mainly observed in the northern part of The Netherlands. Induced earthquakes in the Netherlands have been observed at shallow depths with magnitudes up to ML = 3.5. Recorded strong accelerations are usually short in duration but have incidentally reached 0.3g. Currently, a study group is investigating the suitability of EC8 approach for Dutch conditions, the different seismic engineering approaches in Belgium and Germany, the implication of induced seismicity and a uniform engineering approach for sensitive structures, adopting (seismic) risk assessment.
