SEISPRHO is an interactive computer program for processing and interpreting high-resolution seismic reflection profiles developed using the Delphi/Kylix multiplatform programming environment. For this reason, it is available under Windows and Linux operating systems. The program allows the users to handle SEG-Y data files (and other non-standard formats) carrying out a processing sequence over ...

An explicit procedure is presented for computing both model and data resolution matrices within a Paige-Saunders LSQR algorithm for iterative inversion in seismic tomography. These methods are designed to avoid the need for an additional singular value decomposition of the ray-path matrix. The techniques discussed are completely general since they are based on the multiplicity of equivalent exa...

Existing seismic instrumentation systems do not yet have the capability to recover the physical dynamics with sufficient resolution in real time. Currently, seismologists use centralized tomography inversion algorithm for which the data is gathered either manually from each station or by using limited number of expensive broadband stations. This scheme can take months to generate tomography and...

The 3 August 2014 Ludian earthquake with a moment magnitude scale (Mw) of 6.1 induced widespread landslides in the Ludian County and its vicinity. This paper presents a preliminary analysis of the distribution patterns and characteristics of these co-seismic landslides. In total, 1826 landslides with a total area of 19.12 km2 triggered by the 3 August 2014 Ludian earthquake were visually interp...

As part of the project “Management of Georisk” (MANGEONAD) of the Federal Institute for Geosciences and Natural Resources (BGR), Hanover, high resolution shallow shear-wave reflection seismics was applied in the Indonesian province Nanggroe Aceh Darussalam, North Sumatra in cooperation with the Government of Indonesia, local counterparts, and the Leibniz Institute for Applied Geosciences, Hanov...

SUMMARY Seismic inversion produces model estimates which are at most unique in an average sense. The model resolution matrix quantiies the spatial extent over which the estimate averages the true model. Although the resolution matrix has traditionally been deened in terms of the singular value decomposition of the discretized forward problem, this computation is prohibitive for inverse problems...

In this thesis, we study the theory of Isotropic Multiresolution Analysis (IMRA) and its application to image analysis problems that require rotational invariance. Multiresolution Analysis (MRA) is a mathematical tool that gives us the ability to process a signal or an image at multiple levels of resolution and detail. IMRA is a new type of MRA for which the core resolution sub-space is invaria...

2. Summary The Earth consists of the crust, mantle (Note #1), outer core and inner core (Note #2). The D" (pronounced “Dee double prime”) layer is the name given to the lowermost several hundred km of the mantle, directly below which is the molten outer core, which is composed primarily of iron. The temperature and chemical composition within D" vary rapidly as the distance to the core-mantle b...
