We present a complete inventory of the historical Strasbourg seismograms housed at École et Observatoire des Sciences de la Terre (EOST), University Strasbourg, France. Although published seismological records date back to 1892, station was officially created in 1900, with structure specifically built for monitoring. The presence highly motivated and active scientists from outset, along unique ...

Seismic modeling plays an important role in geophysics and seismology for estimating the response of seismic sources a given medium. In this work, we present MATLAB-based package, FDwave3D, synthetic wavefield seismogram 3D anisotropic media. The simulation is carried out using finite-difference method over staggered grid, it applicable to both active passive surveys. code package allows incorp...

We present a graphical user interface to facilitate the processing of teleseismic shear-wave splitting observations. In contrast to a fully automated technique, we present a manual, per-event approach that maintains user control during the sequence of processing. The SplitLab environment is intended to undertake the repetitive processing steps while enabling the user to focus on quality control...

A slight modification to Fourier spectral factorization enables deconvolution to preserve and enhance seismogram polarities. It spikes the center lobe of the Ricker wavelet. It works by tapering at small lags the antisymmetric part of the time-domain representation of the log spectrum.

AbstructThe impact of pictorial knowledge representation is demonstrated for two examples of time series analysis in seismology. The approaches perform a) automated recognition of known event signatures and b) high-resolution onset timing of later phases. Both methods work well under extreme conditions of noise and achieved human-like performance in recognizing known situations. Crucial for thi...

SUMMARY Wave trains in high-frequency seismograms of local earthquakes are mostly composed of incoherent waves that are scattered by distributed heterogeneities. Their waveforms are very complex and significantly different from those computed for conventional layered structures; however, their envelopes are repeatable, frequency dependent, and vary regionally. Well-logs obtained from deep boreh...
