Interactive visualization of scattered moment tensor data

چکیده
Moment tensors derived from seismic measurements during earthquakes are related to stress tensors and keep important information about surface displacement in the earth’s mantle. We present methods facilitating an interactive visualization of scattered moment data to support earthquake and displacement analysis. For this goal, we combine and link visualizations of spatial location and orientation information derived from moment tensor decompositions. Furthermore, we contribute new tensor glyphs highlighting the indefinite character of moment tensors as well as novel tensor clustering and averaging techniques to aid interactive visual analysis and ease the challenges of interpreting moment tensor data.

Visualization and multivariate clustering of scattered moment tensors
Moment tensors are indefinite tensors derived from seismic measurements and encode important information about earthquakes and surface displacement in the earth’s mantle. Appropriate analysis of scattered moment tensor fields requires multi-scale visualization to identify related seismic events. For this matter we provide a visualization of the tensor field at different scales based on multivar...
متن کاملMulti-field visualization
Modern science utilizes advanced measurement and simulation techniques to analyze phenomena from fields such as medicine, physics, or mechanics. The data produced by application of these techniques takes the form of multi-dimensional functions or fields, which have to be processed in order to provide meaningful parts of the data to domain experts. Definition and implementation of such processin...
متن کاملTensor Approximation in Visualization and Graphics: Background Theory
This compendium on tensor approximation (TA) gives an overview on typical tensor approximation notation and definitions. TA is a tool for data approximation in higher orders. Precisely speaking, TA is an higher-order extension of the matrix singular value decomposition and is a generalization of a data factorization of multidimensional datasets into a set of bases and coefficients. TA consists ...

متن کاملInteractive Visualization of Multidimensional Data
Interactive data visualization concerns the real time manipulation of sampled and computed data for comprehensive display. The goal of the visualization is to bring to the user a deeper understanding of the data as well as the underlying physical laws and properties. In this survey paper I focus on two problem areas relating to interactive data visualization. The rst is in data reduction and de...
