Development of a seismic site-response zonation map for the Netherlands

Earthquake site response is an essential part of seismic hazard assessment, especially in densely populated areas. The shallow geology of the Netherlands consists of a very heterogeneous soft sediment cover, which has a strong effect on the amplitude of ground shaking. Even though the Netherlands is a low- to moderate-seismicity area, the seis...

Time-dependent Seismic Footprint of Thermal Loading for Geothermal Activities in Fractured Carbonate Reservoirs

This paper describes and deploys a workflow to assess the evolution of seismicity associated to injection of cold fluids close to a fault. We employ a coupled numerical thermo-hydro-mechanical simulator to simulate the evolution of pressures, temperatures and stress on the fault. Adopting rate-and-state seismicity theory we assess induced...

Reliability based code making for seismic assessment under gas extraction

Until recently earthquakes were not taken into account in the Dutch Building Decree and other Dutch building regulations. Although in 1992, an earthquake happened in Roermond with a magnitude of 5.8 on the Richter scale which damaged buildings, this was not seen by the law makers as an argument for the introduction of regulations for earthquake...

The impact of viscoelastic caprock on fault reactivation and fault rupture in producing gas fields

Summary of the EU project GEISER on induced seismicity in geothermal engineering

GEISER was a European project on understanding and mitigation of induced seismicty in geothermal operations. The project involved several European research institutions as well as industry and was funded by the European Commission within FP7. GEISER addressed a better understanding of the key parameters that control induced seismicity in...

Reliability Based assessment of buildings under earthquakes due to gas extraction

In the northern part of the Netherlands over de last decades shallow earthquakes are induced due to large scale gas extraction from the Groningen gas field. Earthquakes occur due to the compaction of the reservoir rock, which leads to subsidence at surface and strain build-up in the reservoir rock and existing faults. The induced earthquakes...

Geothermal engineering integrating mitigation of induced seismicity in reservoirs - The European GEISER project

The GEISER (Geothermal Engineering Integrating Mitigation of Induced SEismicity in Reservoirs) project is co-funded by the European Commission to address the mitigation and understanding of induced seismicity (IS) in geothermal engineering. The aim of the project is to contribute to the improvement of the concept of EGS by investigating the role...

Testing a logic tree approach for archaeoseismology to the ancient city of Pinara (SW Turkey)

Geologists, seismologists, as well as archaeologists increasingly apply archaeoseismological investigations to study possible natural causes of damage of a site and to assess the regional seismic hazard risks. Archaeoseismological investigations enable the obtaining of diverse data on past earthquakes and allow for an application of different...

Correlation between hydrocarbon reservoir properties and induced seismicity in the Netherlands

Earthquakes induced by gas production are a social concern in the Netherlands. Over the last two decades, a total of about 350 such earthquakes have been recorded, with magnitudes ranging up to 3.5 on Richter's scale. The new Dutch mining law prescribes the operators to give a quantitative estimation of the likelihood of future seismic activity ...
