...Zack Spica; Mathieu Perton; Nori Nakata; Xin Liu; Gregory C. Beroza ABSTRACT The Groningen gas field in the northern Netherlands is subject to production‐induced earthquakes and has quickly become one of the seismologically best‐instrumented areas on Earth. Accurate quantification of seismic hazard...

... stations of the Loppersum array, and for several stations of the Wittewierum array. The results are shown in Figure  A1 and discussed in Appendix  A . One notable finding of this analysis is that the level of noise is high at almost all stations and frequencies, likely because of the vicinity...

(a) Map view of the Groningen gas field area. White areas depict urban centers. The location of the Groningen gas field in the northern part of the Netherlands is shown in the map in the lower left corner of the figure (red contour). The blue contour depicts the outline of the gas field. The vertical gray dashed line depicts the location where the section of the velocity model shown in Figure 2a has been taken. Orange triangles depict the G‐array. The 1D velocity model at station G23 (encircle) is shown in Figure 2b. Vertical view of one shallow borehole of this array is shown in the orange box on the right side. Green triangles depict the borehole array operated by the Royal Netherlands Meteorological Institute (KNMI) since 1991. The pink box on the map is zoomed in the upper right corner of the figure. It depicts the Wittewierum array and its 100 vertical‐component geophones. It is reported as “Wi” in the legend of the figure. Small blue triangles depict the Loppersum (northern) and Borgsweer (eastern) arrays. They are reported as “TA” (standing for Transportable Array) in the legend of the figure. Two white triangles in the middle of the Loppersum array depict the deep borehole arrays, namely SDM (western) and ZRP (eastern). A vertical view of these arrays at reservoir depth is shown in the upper left corner of the figure. (b) Summary of the start and end times of the different arrays used in this study. G, G‐array; Wi, Wittewierum; Lop, Loppersum. SDM and ZRP are the two deep borehole arrays. The gray rectangle corresponds to a period when the G‐array was under construction.

Image
(a) Location of the Groningen gas field in the northern Netherlands. (b) Map view of the Groningen gas field area. Blue contour shows the boundary of the gas field. Orange triangles depict the shallow borehole sites of the G‐array, which consists of 70 accelerographs at the surface collocated with a borehole in which three to four geophones are installed at depth intervals of 30, 50, or 75 m. Small red triangles depict stations of the Loppersum array, reported as Transportable Array (TA) in the legend. (c) Loppersum array (black triangles) and the surrounding stations of the G‐array (orange triangles). The two green triangles depict the deep borehole locations: ZRP (western) and SDM (eastern). The line of five stations close to the shallow borehole G18 are shown in red. Inversion results for these stations are highlighted in Figure 3. A detailed description of some of the seismic arrays in the Groningen area is provided in Spica et al. (2018).

...Laura Gulia Abstract The Groningen gas field, located in the northeast of The Netherlands, is the Europe’s largest onshore gas field. It was discovered in 1959 and production started in 1963: Continuous production leads to reservoir compaction and subsidence, gradually loading preexisting fault...
