Continuous automatic classification of seismic signals of volcanic origin at Mt. Merapi, Java, Indonesia
… Gegensatz zu Standardverfahren, bei denen in der Seismologie üblicherweise nur der Startzeitpunkt eines seismischen Ereignisses detektiert wird, werden in dem untersuchten Verfahren seismische Ereignisse in ihrer Gesamtheit erfasst und zudem im selben Schritt bereits klassifiziert.

Source parameters of the major historical earthquakes in the Tien-Shan region from the late 19th to the early 20th century
The Tien-Shan and the neighboring Pamir region are two of the largest mountain belts in the world. Their deformation is dominated by intermontane basins bounded by active thrust and reverse faulting. The Tien-Shan mountain belt is characterized by a very high rate of seismicity along its margins as …

Der obere Mantel in der Eifel-Region untersucht mit der Receiver Function Methode
Die Eifel ist eines der jüngsten vulkanischen Gebiete Mitteleuropas. Die letzte Eruption ereignete sich vor ungefähr 11000 Jahren. Bisher ist relativ wenig bekannt über die tieferen Mechanismen, die für den Vulkanismus in der Eifel verantwortlich sind. Erdbebenaktivität deutet ebenso darauf hin, …

Recognition and investigation of temporal patterns in seismic wavefields using unsupervised learning techniques
Modern acquisition of seismic data on receiver networks worldwide produces an increasing amount of continuous wavefield recordings. Hence, in addition to manual data inspection, seismogram interpretation requires new processing utilities for event detection, signal classification and data …

Development of techniques for earthquake microzonation studies in different urban environment
The proliferation of megacities in many developing countries, and their location in areas where they are exposed to a high risk from large earthquakes, coupled with a lack of preparation, demonstrates the requirement for improved capabilities in hazard assessment, as well as the rapid adjustment …

Inversion of seismic source parameters for weak mining-induced and natural earthquakes
The purpose of this thesis is to develop an automated inversion scheme to derive point and finite source parameters for weak earthquakes, here intended with the unusual meaning of earthquakes with magnitudes at the limit or below the bottom magnitude threshold of standard source inversion routines. …

Source array and receiver array analysis of Vogtland/ West Bohemia earthquake clusters
Die Region Vogtland/ West Böhmen im Grenzgebiet zwischen Deutschland und Tschechien ist bekannt für ihre geologische Aktivität. Holozäner Vulkanismus, Gasaustritte an Mofetten und Quellen und wiederkehrende Erdbebenschwärme sind Ausdruck geodynamischer Prozesse im Untergrund. Während des …

Statistical analysis of natural and induced seismicity catalogues
Hlavním cílem této práce je analýza statistických vlastností přírodních a indukovaných seismických katalogů. Porovnáváme časové a magnitudové vlastnosti různých druhů zemětřesných katalogů a hledáme jejich podobnosti a odlišnosti. Na deset různých seismických katalogů přírodního a indukovaného …

Analysis and modeling of transient earthquake patterns and their dependence on local stress regimes
Investigations in the field of earthquake triggering and associated interactions, which includes aftershock triggering as well as induced seismicity, is important for seismic hazard assessment due to earthquakes destructive power. One of the approaches to study earthquake triggering and their …

The character of the core-mantle boundary : a systematic study using PcP
Assuming that liquid iron alloy from the outer core interacts with the solid silicate-rich lower mantle the influence on the core-mantle reflected phase PcP is studied. If the core-mantle boundary is not a sharp discontinuity, this becomes apparent in the waveform and amplitude of PcP. …

Detection and Kirchhoff-type migration of seismic events by use of a new characteristic function
The classical method of seismic event localization is based on the picking of body wave arrivals, ray tracing and inversion of travel time data. Travel time picks with small uncertainties are required to produce reliable and accurate results with this kind of source localization. Hence recordings, …
