The postglacial uplift and surrounding subsidence in Scandinavia is well described as close to regular, and the phenomenon is similar on timescales of tens, hundreds and thousands of years studied via geodesy, seismology and geology. Searches for irregularities in the form of earthquakes claimed in the scientific literature have disclosed many earthquakes right after the Ice Age, 9000 yr ago, and some later cases for further evaluation. In a previous report, the present authors have mentioned doubts about the validity of some of the most significant claimed irregularities. In the present paper, a review is made of these significant claimed irregularities in the south-western flank of the Scandinavian postglacial uplift and subsidence via literature studies of geodetic and geological claims of earthquakes as well as discussions in the field. Geodetic observations exist for all of Scandinavia that describe the phenomenon on a scale of 10s100s of years. Earthquake observations in seismology are of relevance in the same timescales. Geological studies of dated shore lines describe the postglacial vertical earth-surface motion in a quite different timescale of 100s1000s of years. There is a need for integration of these observations geographically. This is happening in the various timescales in the DynaQlim project. The review finds the claims unlikely to be earthquakes concerning the following: (1) geodynamical motion in the Copenhagen area, (2) a palaeo-earthquake in Lжsш and (3) the recently proposed water level discrepancy in the southern part of Denmark. The assessment is less certain, but falls to improbable when concerning (4) proposed palaeo-earthquakes by Hallandsеsen in south-western Sweden. Minimize

For the nonlinear eigenvalue problem T (#)x = 0 we propose an iterative projection method for computing a few eigenvalues close to a given parameter. The current search space is expanded by a generalization of the shift-and-invert Arnoldi method. The resulting projected eigenproblems of small dimension are solved by inverse iteration. The method is applied to a rational eigenvalue problem governing damped vibrations of a structure. Minimize

Decision making on spatial planning problems has to integrate recent advancements on geographical information systems with a framework that supports fair, rational and efficient decision making procedures. Such a framework will assist government and businesses with the retrieval, use and reuse of information in cooperative, distributed planning procedures requiring access to spatial data. This paper gives an overview of a computer-mediated group decision support system for the World Wide Web, namely ZENO. The target is to provide intelligent assistance to human mediators and other kinds cf “trusted third partiesi during the above procedures. The role of the system is to remain neutral and help assure that the interests and goals of all members of a group, regardless of their status, are respected and appreciated. In this paper, the system's features are illustrated with a retrospective model of a real urban planning example, concerning the allocation of a new technology park in the area of the city of Bonn, where more than eighty communities, local and federal authorities, and other organizations have been requested to submit their suggestions, objections and comments on a spatial planning problem.

The presented study is a part of the passive seismic experiment PASSEQ 20062008, which took place around the Trans-European Suture Zone (TESZ) from May 2006 to June 2008. The data set of 4195 manually picked arrivals of teleseismic P waves of 101 earthquakes (EQs) recorded in the seismic stations deployed to the east of the TESZ was inverted using the non-linear teleseismic tomography algorithm TELINV. Two 3-D crustal models were used to estimate the crustal travel time (TT) corrections. As a result, we obtain a model of P -wave velocity variations in the upper mantle beneath the TESZ and the East European Craton (EEC). In the study area beneath the craton, we observe up to 3% higher and beneath the TESZ about 23% lower seismic velocities compared to the IASP91 velocity model. We find the seismic lithosphereasthenosphere boundary (LAB) beneath the TESZ at a depth of about 180 km, while we observe no seismic LAB beneath the EEC. The inversion results obtained with the real and the synthetic data sets indicate a ramp shape of the LAB in the northern TESZ, where we observe values of seismic velocities close to those of the craton down to about 150 km. The lithosphere thickness in the EEC increases going from the TESZ to the NE from about 180 km beneath Poland to 300 km or more beneath Lithuania. Moreover, in western Lithuania we find an indication of an upper-mantle dome. In our results, the crustal units are not well resolved. There are no clear indications of the features in the upper mantle which could be related to the crustal units in the study area. On the other hand, at a depth of 120150 km we indicate a trace of a boundary of proposed palaeosubduction zone between the East Lithuanian Domain (EL) and the West Lithuanian Granulite Domain (WLG). Also, in our results, we may have identified two anorogenic granitoid plutons. Minimize

Upper mantle structure around the Trans-European Suture Zone obtained by teleseismic tomography

Description:

The presented study aims to resolve the upper mantle structure around the Trans-European Suture Zone (TESZ) which is the major tectonic boundary in Europe.

The presented study aims to resolve the upper mantle structure around the Trans-European Suture Zone (TESZ) which is the major tectonic boundary in Europe. The data of 183 temporary and permanent seismic stations operated during the period of the PASsive Seismic Experiment PASSEQ 20062008 within the study area from Germany to Lithuania was used to compile the dataset of manually picked 6008 top quality arrivals of P waves from teleseismic earthquakes. We used the non-linear teleseismic tomography algorithm TELINV to perform the inversions. As a result, we obtain a model of P wave velocity variations up to about ±3% compared to the IASP91 velocity model in the upper mantle around the TESZ. The higher velocities to the east of the TESZ correspond to the older East European Craton (EEC), while the lower velocities to the west of the TESZ correspond to younger Western Europe. We find that the seismic lithosphere-asthenosphere boundary (LAB) is more distinct beneath the Phanerozoic part of Europe than beneath the Precambrian part. To the west of the TESZ beneath the eastern part of the Bohemian Massif, the Sudetes Mountains and the Eger Rift the negative anomalies are observed from the depth of at least 70 km, while under the Variscides the average depth of the seismic LAB is about 100 km. We do not observe the seismic LAB beneath the EEC, but beneath Lithuania we find the thickest lithosphere of about 300 km or more. Beneath the TESZ the asthenosphere is at a depth of 150180 km, which is an intermediate value between that of the EEC and Western Europe. The results imply that the seismic LAB in the northern part of the TESZ is of a shape of a ramp dipping to the NE direction. In the southern part of the TESZ the LAB is shallower, most probably due to younger tectonic settings. In the northern part of the TESZ we do not recognize any clear contact between Phanerozoic and Proterozoic Europe, but further to the south we may refer to a sharp and steep contact on the eastern edge of the TESZ. Moreover, beneath Lithuania at the depth of 120150 km we observe the lower velocity area following the boundary of the proposed palaeosubduction zone. Minimize
