“…This point should be mentioned in light of the recent results of surface deformation in this area, which is consistent with a dynamic uprise of the deep mantle below the volcanic field [Kreemer et al, 2020, Ritter et al, 2001, Dahm et al, 2020. Using the local seismic network of the University of Cologne and relocation process, Hinzen et al [2021] show that whereas seismicity is lacking where the surface uplift is the largest (∼1 mm/yr), clusters of seismicity concentrate where gradients of vertical movements are measured. Peculiar events such as deep low frequency earthquakes have been identi-fied and located from 10 to 40 km of depth revealing vertical paths of ascending magma [Hensch et al, 2019].…”

“…Over the instrumental time, we determine a b-value of 1.24 (Supplementary Figure 7a), larger than the one (0.93) from the previous study of Rabin et al [2018]. The difference of 0.3 between both values can be due to the use of ML and M w as underlined by Hinzen et al [2021] for the North Rhine Region. The seismicity is spatially distributed over the whole region with small areas of more concentrated seismic events, without a clear identification of the active faults (Figure 6).…”

The region of northeastern France is affected by low-magnitude background seismicity, with the rare occurrence of moderate earthquakes, which gives this region a non-negligible seismic risk. We provide an overview of the seismicity and seismotectonics of this intraplate domain and of its subregions: the Upper-Rhine Graben (URG), the external range and foreland of Jura, the Vosges, northern France and southern Belgium. Previously published catalogues over historical and instrumental times are used, and the epicentral distribution of earthquakes is compared to known tectonic structures, and the recently computed deformation field. Although no large earthquakes with M w > 6.0 occurred since the 1356 Basel seismic event (Io IX, MKS), the recent identification of active faults suggests periods of high seismic strain rates in the past. The origin of the seismic activity in each of these sub-regions, characterized by low to very-low strain rates, is attributed to pre-existing faults reactivated under specific natural or anthropogenic conditions.

“…Two large active faults bound the Roer Valley Graben: the Peel Boundary fault to the north-east and the Feldbiss fault to the south-west. The earthquakes are generally limited in magnitude (M L <4.0) and occur at depths of around 10 km (Hinzen et al, 2020). Occasionally the earthquakes are powerful enough to cause damage.…”

We present an overview of induced seismicity due to subsurface engineering in the Netherlands. Our overview includes events induced by gas extraction, underground gas storage, geothermal heat extraction, salt solution mining and post-mining water ingress. Compared to natural seismicity, induced events are usually small (magnitudes ≤ 4.0). However, due to the soft topsoils in combination with shallow hypocentres, in the Netherlands events exceeding magnitude 1.5–2.0 may be felt by the public. These events can potentially damage houses and infrastructure, and undermine public acceptance. Felt events were induced by gas production in the north of the Netherlands and by post-mining water ingress in the south-east. Notorious examples are the earthquakes induced by gas production from the large Groningen gas field with magnitudes up to 3.6. Here, extensive non-structural damage incurred and public support was revoked. As a consequence, production will be terminated in 2022 leaving approximately 800 billion cubic metres of gas unexploited. The magnitudes of the events observed at underground gas storage, geothermal heat production and salt solution mining projects have so far been very limited (magnitudes ≤ 1.7). However, in the future larger events cannot be excluded. Project- or industry-specific risk governance protocols, extensive gathering of subsurface data and adequate seismic monitoring are therefore essential to allow sustainable use of the Dutch subsurface now and over the decades to come.

“…Tectonic seismicity occurs mainly in the Roer Valley Graben (yellow circles, Figure 2) which is part of a larger basin and range system in Western Europe, the Rhine Graben Rift System. At the beginning of the Quaternary, the rate of subsidence in the Roer Valley Graben has significantly increased (Geluk et al, 1995;Houtgast and Van Balen, 2000) and the rift system still shows active extension (Hinzen et al, 2020). The largest earthquake recorded (M w=5.8) in the Netherlands was in Roermond in 1992, due to extensional activity along the Peel Boundary Fault (Paulssen et al, 1992).…”

Abstract. 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 seismic wave propagation and in particular on the amplitude of ground shaking, resulting in significant damage on structures despite the fact that the events are of small magnitude. Even though it is a low-to-moderate seismicity area, the seismic risk cannot be neglected, in particular, because shallow induced earthquakes occur. The aim of this study is to establish a nationwide site-response zonation by using the lithostratigraphy, earthquake- and ambient vibration recordings. In the first step, we constrain the parameters (velocity contrast and shear-wave velocity) that are indicative of ground-motion amplification in the Groningen area. For this, we combine ambient vibration and earthquake recordings using resp. the horizontal-to-vertical spectral ratio method (HVSR), borehole empirical transfer functions (ETFs) and amplification factors (AFs). This enables us to define an empirical relationship between measured earthquake amplification from the ETF and AF, and amplification estimated with the HVSR derived from the ambient seismic field. Therewith, we show that the HVSR can be used as a first proxy for amplification. Subsequently, HVSR curves throughout the Netherlands are estimated. The resulting peak amplitudes largely coincide with the in-situ lithostratigraphic sequences and the presence of a strong velocity contrast in the near-surface. Next, sediment profiles representing the Dutch shallow subsurface are categorized into five classes, where each class is representing a level of expected amplification. The mean amplification for each class, and its variability, is quantified using 66 sites with measured earthquake amplification (ETF and AF) and 115 sites with HVSR curves. The site-response (amplification) zonation map for the Netherlands is designed by transforming published geological 3D grid cell models into the five classes and an AF is assigned to most of the classes. This presented site-response assessment on a national scale is important for a first identification of regions with increased seismic hazard potential, for example at locations with mining or geothermal energy activities.
