    The SeisComP seismological software package (2008)

    Details
    Publication Date: 2024-06-14
    Description: Abstract
    Description: SeisComP is a seismological software for data acquisition, processing, distribution and interactive analysis. The seismological software package has evolved within a decade from pure acquisition modules to a fully featured real-time earthquake monitoring software. The SeedLink protocol for seismic data transmission has been the core of SeisComP from the very beginning. Later additions included simple, purely automatic event detection, location and magnitude determination capabilities. Especially within the development of the 3rd-generation SeisComP, also known as SeisComP3 automatic processing capabilities have been augmented by graphical user interfaces (GUIs) for visualization, rapid event review and quality control.Communication between the modules is achieved using a dedicated messaging system that allows distributed computing and remote review. For seismological metadata exchange export/import tools to/from QuakeML and FDSN StationXML are available, which also provide convenient interfaces with 3rd-party software. The initial SeisComP3 development took place at GFZ between 2006 and 2008 within the GITEWS project (German Indonesian Tsunami Early Warning System) and continued with increasing engagement of gempa GmbH, a software company established by the initial development team of the GFZ.

    Description: Die Andenkordillere entstand entlang des westlichen Randes von Südamerika aufgrund der Subduktion der ozeanischen Nazca-Platte unter die kontinentale Südamerikaplatte seit dem Jura. Als solche werden die Anden als ein klassisches Beispiel eines Orogens entlang eines aktiven Kontinentalrandes betrachtet. Obwohl die gegenwärtige Physiographie das Ergebnis der Andinen Tektonik ist, sind die Zentralanden das Ergebnis von einem komplexen Zusammenspiel von Präkambrischen und Paläozoischen Terrane-Akretionen und Phasen von Kompression und Extension. Die Puna und die Ostkordillere spielen in diesem Zusammenhang eine entscheidende Rolle in der tektonischen Entwicklung der Zentralanden. Die vorliegende Untersuchung befasst sich mit dem Gebiet der nördlichen argentinischen Puna und der Ostkordillere, von etwa 22°S bis 24°S und 65 °W bis 66°30' W. Es wurden etwa 1200 km Seismik interpretiert, deren Ergebnis als Randbedingung in die Konstruktion des gravimetrischen 3D Modells des Gebietes einging.
    Description: The Andes Mountains developed along the western margin of SouthAmerica in response to the subduction of the oceanic Nazca Plate below the South American plate since the Jurassic times. It is considered as one of the classic examples of a mountain chain developed in an active continental margin. Although their present physiography is given by the Andean tectonics, the Central Andes are the result of complex interplay of Precambrian and Paleozoic terrane accretion and phases of compression and extension. The Puna and Eastern Cordillera represent key elements in the tectonic evolution of the Central Andes. The present study covers a region of the northern Puna and Eastern Cordillera extending from approximately 22°S to 24°S and 65 °W to 66°30'W in Argentina. About 1200 km of seismic lines were interpreted and were used as a geometrical constraint for the construction of a 3D gravity model of the area.

    Description: In der vorliegenden Arbeit wird die Krustenstruktur im östlichen Andenvorland untersucht. Das Gebiet umfaßt den Nordwesten Argentiniens, zwischen dem 22° und 25° südlichen Breitengrad und dem 66° und 62° westlichen Längengrad. Aus morphologischer Sicht befindet sich das Untersuchungsgebiet im Übergang zwischen dem Subandin (Sierras Subandinas) und der südlichen Ostkordillere zum Chaco Vorland (Llanura Chaqueña). Im Untersuchungsgebiet zeichnet sich ein Wechsel in den tektonischen Strukturen ab, welcher als Interaktion zwischen der tertiären Andenorogenese und kretazischen Riftbildungen gedeutet wird. Dieser als Inversionstektonik bekannte tektonischer Stil hat nicht nur oberflächennahe Strukturen hervorgerufen, sondern auch tiefgreifende Massenveränderungen verursacht. Teile dieser Modifikationen sind in der Signatur des Schwerefeldes erhalten geblieben, und somit ist die Interpretation gravimetrischer Meßergebnisse zusammen mit den geologischen Randbedingungen eine Grundvorraussetzung zur Untersuchung dieser tektonischen Interaktion. Zum Verständnis dieser Strukturen war es notwendig, sowohl den Teil des Beckens zu untersuchen, welcher nicht von der andinen Orogenese betroffen ist, als auch jenen der direkt in die letztere miteinbezogen wurde. Aus gravimetrischer Sicht ist die Bougueranomalie des Gebietes stark vom Effekt der Andenwurzel geprägt. Jedoch deuten einige Abweichungen auf die Existenz lokalerer Störkörper hin, die Ziel der Modellierung waren. Ein solcher Störkörper wurde am südöstlichen Rand des kretazischen Rifts identifiziert. Die Modellierung wurde einerseits zweidimensional durchgeführt um einen Überblick über das Gebiet zu bekommen. Eine regionale 3D Modellierung führte dann zu einer präziseren Interpretation des Gebietes. Insbesondere wurde dabei der Effekt überschobener Riftschollen am Ostrand des Beckens untersucht. Diese Überschiebungen drücken sich im gravimetrischen Restfeld als deutliche positive Anomalie aus. Allerdings kann diese Anomalie nicht direkt mit einem Astenosphärenanstieg, welcher durch Riftbildung entstanden sein könnte, in Einklang gebracht werden - wie von einigen Autoren vermutet wurde. Eine weitere modellierte Struktur bildete die Vortiefe, welche durch die Auflast der andinen Überschiebung enstanden ist. Die dadurch hervorgerufenen negativen Anomalien bilden einen deutlichen Kontrast zu der beschriebenen positiven Anomalie im Vorland, der sich auch im Restfeld als starker Gradient äußert. Die 2D Modellierung erbrachte folgende Ergebnisse: im anorogenen Breich des Untersuchungsgebietes wurde die Existenz einer deutliche Asymmetrie des Beckens bestätigt, mit einer nach Südosten geneigten Riftabscherungsfläche. Die Orogenese hinterließ deutliche Spuren in der Reaktivierung der Abscherungen wobei entlang der südostvergenten Störungen tieferes Krustenmaterial emporgeschoben wurde. Mit einer größeren Dichte wird dieser Vorgang als Ursache der positiven Anomalie intepretiert. Westvergente Störungen scheinen nur oberflächennahe Bereiche miteinbezogen haben. Im regionalen 3D Modell wurde ein Ansteigen der Unterkruste unterhalb des Beckens angenommen. Die asymmetrische Anordnung dieses Anstiegs deutet eher auf einen kompressive tektonischen Effekt hin als auf eine residuale Krustenverdünnung. Zusammenfassend kann gesagt werden, daß sich in diesem Breich im Schwerefeld die Effekte des Andengradienten mit denen der überschobenen Basement-Tektonik und der Vorlandtief kombinieren und als solche fur einen starken lokalen Gradienten am Rande des Effekts der Andenwurzel verantwortlich sind.
    Description: In the present study, the structure of the crust beneath the eastern Andean foreland is analyzed. The area comprises part of northwest Argentina, between 22° and 25° S and 66° and 62° W. In terms of morphotectonics, the area studied covers the transition between the Sierras Subandinas (Subandean Ranges) and the southern part of the Cordillera Oriental (Eastern Cordillera) to the Chaco plains (Llanura Chaqueña). In the area, a pervasive change controls the tectonic features, which is interpreted as a consequence of the interaction between the Andean orogeny and preexistent Cretaceous rifting. This inversion tectonics did not only result in a particular suite of near to surface structures but also modified deeply the mass distribution within the crust. This changes in mass distributions and hence density contrasts is evidenced by the gravity field. As such, a careful analysis of gravity data together with the geological boundary conditions are the basis for an analysis of this tectonic interaction. Understanding these structures implied to analyse not only the part of the rift involved in the Andean compressive orogenesis but also that part where original extensional features are still preserved. From a gravimetrical point of view, the Bouguer-anomaly of the area shows a strong overprint related with the Andean root. Some smaller changes in the field however indicate the existence of local sources, which where the target of the modelling. Such a change had been indentified at the southeastern edge of the Cretaceous rift. Modelling was performed towfold. As such, a 2D model was made in order to get an insight into the regional aspects of the area. A more detailed 3D model led to a more precise interpretation of the area. In particular, the effect of the inverted rift tectonics at the eastern edge of the basin was studied. These upthrusts correlate with a readily identifiable positive anomaly within the residual field. The anomaly neverthless cannot be directly related with an astenospheric uprise, preserved since the rifting stage, as suggested by some authors. In addition, the foredeep related with the tectonic load of the Andean overthurst, was modelled. The negative anomalies generated during this process, show a strong contrast in comparison with the positive anomaly described above, depicted also by a prominent gradient in the residual field. 2D modelling led to the following results. In the region, where Creataceous rifting structures were not overprinted by the Andean orogeny an obvious asymmetry of the basin was defined, being the master detachment dipping to the northeast. The orogeny left evidences of reactivation, where the structures of the southeastern edge were the pathways of the uplift if deeper crustal material with a higher density. This process may be responsible for a part of the positive anomaly mentioned. Structures located at the western and northwestern edge of the basin seem to have only involved nearer-to surface structures. The 3D model assumed a slight uprise of the lower crust beneath the basin. The asymmetry in goemetty seem to stand more for a tectonic effect than for a remanent thinned crust. As a summary, the gravity field in this area shows the combined effects of the regional Andean gradient with the more local effects of the basement tectonics (inverted rifting) and the overthrusted foredeep. Hence, at least these three factors seem to be responsible for the strong local gradient in a lateral position of the Andean root.

    Column-store support for RDF data management (2008)

    Details
    Publication Date: 2024-04-19
    Description: This paper reports on the results of an independent evaluation of the techniques presented in the VLDB 2007 paper "Scalable Semantic Web Data Management Using Vertical Partitioning", authored by D. Abadi, A. Marcus, S. R. Madden, and K. Hollenbach [1]. We revisit the proposed benchmark and examine both the data and query space coverage. The benchmark is extended to cover a larger portion of the query space in a canonical way. Repeatability of the experiments is assessed using the code base obtained from the authors. Inspired by the proposed vertically-partitioned storage solution for RDF data and the performance figures using a column-store, we conduct a complementary analysis of state-of-the-art RDF storage solutions. To this end, we employ MonetDB/SQL, a fully-functional open source column-store, and a well-known -- for its performance -- commercial row-store DBMS. We implement two relational RDF storage solutions -- triple-store and vertically-partitioned -- in both systems. This allows us to expand the scope of [1] with the performance characterization along both dimensions -- triple-store vs. vertically-partitioned and row-store vs. column-store -- individually, before analyzing their combined effects. A detailed report of the experimental test-bed, as well as an in-depth analysis of the parameters involved, clarify the scope of the solution originally presented and position the results in a broader context by covering more systems.
