“…Figure 15 shows values of misorientations of all stations in the study area obtained with the use of three described methods; the permanent station GKP is outside the study area, but it is shown for comparison, as previous studies also reported its significant misorientation - Vecsey et al (2014) reported 41 • , Wilde-Piórko et al (2017) reported 39 and 45 • , and the result of this study is 34-37 • . For many stations, the results derived from the three methods are more or less consistent but with some conspicuous exceptions.…”

Abstract. The paper presents information about the seismic experiment “AniMaLS” which aims to provide a new insight into the crust and upper mantle structure beneath the Polish Sudetes (NE margin of the Variscan orogen). The seismic network composed of 23 temporary broadband stations was operated continuously for about 2 years (October 2017 to October 2019). The dataset was complemented by records from eight permanent stations located in the study area and in the vicinity. The stations were deployed with an inter-station spacing of approximately 25–30 km. As a result, recordings of local, regional and teleseismic events were obtained. We describe the aims and motivation of the project, the station deployment procedure, as well as the characteristics of the temporary seismic network and of the permanent stations. Furthermore, this paper includes a description of important issues like data transmission setup, status monitoring systems, data quality control, near-surface geological structure beneath stations and related site effects, etc. Special attention was paid to verification of correct orientation of the sensors. The obtained dataset will be analysed using several seismic interpretation methods, including analysis of seismic anisotropy parameters, with the objective of extending knowledge about the lithospheric and sublithospheric structure and the tectonic evolution of the study area.

“…It is characterized by a thick three‐layer crust with an additional fast lower crustal layer (Grad et al., 2003). The East European Craton is of Precambrian origin and overlain by a young thin sedimentary cover (Bogdanova et al., 2006) which leads to strong reverberations in the P‐receiver function for SUW (Wilde‐Piórko et al., 2017)…”

Receiver function (RF) analysis is a powerful technique to gain information about the discontinuities in the crust and upper mantle beneath a single three-component seismic station. RFs are essentially time series that are sensitive to the structure near the receiver. The basic principle behind this method is that when a seismic wave is incident upon a discontinuity, mode conversion between the compressional (P) and shear (S) waves will take place in addition to the generation of reflected and transmitted waves. The resulting converted wave (Ps or Sp) will have a time offset with respect to its parent wave, and this time offset is directly proportional to the depth of the discontinuity and the velocity of the layers above. In addition to the direct converted waves, the multiples resulting from reflections and conversions between the discontinuity and the free surface can provide further constraints on the layer thickness and help to resolve the depth-velocity trade-off. The RF can be obtained by deconvolving the vertical component from the radial component of a teleseismic event recorded on a three-component seismometer (Ammon, 1991;Langston, 1979;Owens et al., 1987). Since only a small percentage of the incident energy is converted at a discontinuity, it is difficult to observe these conversions in a single seismogram. A number of RFs can instead be used to measure the crustal thickness and average v v P S / ratios by H-k (crustal thickness-average v v P S / ) stacking for individual stations (Helffrich & Thompson , 2010;Zhu & Kanamori, 2000) or for imaging by common conversion point (CCP) stacking of data from many stations (Dueker & Sheehan, 1997). This, however, requires assumptions on the velocity structure.One method to obtain a detailed velocity structure is to directly invert the calculated RFs using linearized iterative procedures, but Ammon et al. (1990) showed that such inversions of RF contain an inherent tradeoff between the depth to a discontinuity and the velocity above. The primary sensitivity of the RF inversion is to velocity contrasts and relative travel time, not to absolute velocity. This lack of sensitivity to absolute velocity results from the relative S-P travel time constraints along with the limited range of horizontal slowness contained in the data (Ammon et al., 1990). Thus RF data sets are generally inverted jointly with

“…Misorientation of seismometers with respect to the geographic coordinate system is a very important variable for threecomponent seismological analyses that require the rotation of the seismic records from the original geographic coordinates ZNE (vertical, north-south, east-west) into the ZRT (vertical, radial, transverse) or into the ray-oriented LQT (Pwave direction, SV-wave direction, SH-wave direction) coordinate systems. Some examples include earthquake source investigations, anisotropy studies, receiver function analyses or body-and surface-wave polarization studies (e.g., Ekström and Busby 2008;Wilde-Piórko et al 2017, Lim et al 2018). The orientation is usually determined by indirect methods after the installation of the seismometer, and the azimuths of the horizontal components are reported as auxiliary data (e.g., Ekström and Busby 2008).…”

From August 2016 to July 2017, a passive seismic survey was conducted in South Western Iran as a part of a pilot project aimed to improve the imaging in geologically complex areas. Passive seismic methods have shown to be a useful tool to infer the physical properties of the underground geological structures where traditional hydrocarbon exploration methods are challenging. For this purpose, a dense passive seismic network consisting of 119 three‐component borehole seismic stations was deployed over an area of 400 km2 around the city of Dehdasht. This paper focuses on the details of the network design, which was devoted to high‐resolution seismological applications, including local earthquake tomography and seismic attenuation imaging. In this regard, we describe the instrument types and the station installation procedures used to obtain high‐quality data that were used to retrieve three‐dimensional models of P‐ and S‐wave velocity and P‐wave attenuation in the area using tomographic inversion techniques. We also assess the network performance in terms of the seismic ambient noise levels recorded at each station site, and we revise the horizontal orientation of the sensors using surface waves from teleseismic earthquakes.
