The algorithm has been tested in six significant earthquakes (Kozani-Grevena 1995, Aigio 1995, Athens 1999, Lefkada 2003 and Kefalonia 2014) of the Greek territory with analog and digital accelerograms. In addition, the possibility to also perform a signal-to-noise ratio is added as well as to perform causal or acausal filtering. The algorithm is written in Matlab environment, is fast enough and can be used for batch processing or in real-time applications. Besides the corrected time histories, Peak Ground Acceleration, Peak Ground Velocity, Peak Ground Displacement values and the corrected Fourier Spectra are also calculated as well as the response spectra. ![]() ![]() ![]() above the seabed sites on the reduction of vertical motions spectra. The KiK-net data are the waveforms of the 2011 Tohoku-Oki earthquake recorded at the surface by the TKYH12 station. The algorithm follows the basic steps of the correction procedure (instrument correction, baseline correction and appropriate filtering). The paper is devoted to the problem of numerical modeling of earthquake response of. ![]() The main feature of the proposed algorithm is the automatic selection for the cut-off frequencies based on a minimum spectral value in a predefined frequency bandwidth, instead of the typical signal-to-noise approach. The present study focuses on the automated correction of accelerograms, analog and digital. Strong motion recordings are the key in many earthquake engineering applications and are also fundamental for seismic design.
