ShakyGround offers several levels of output which enable the user to check and to evaluate immediately the results of a simulation. Having concluded the numerical processing ShakyGround produces a screen similar to the one below. This screen forms the standard output, which is produced in any case. It consists of a plot concerning the response spectra showing their statistical variation, and a tabel with important signal parameters, i. e., peak ground acceleration, velocity and displacement, RMS-values of the thre types of signal, the duration of strong ground motion (calculated following the concept of HUSID-plots), finally corresponding magnitude values (MS deduced from the seismic moment, MWA as obtained from the simulated signals). All these results can be saved to a georeferenced data base, where they can be easily accessed for futher processing in GIS-applications.

An important tool offered by ShakyGround is the graphical visualization of the single simulated seismograms and response spectra. The possibility of inspecting the single time series and response spectra can be used in order to check whether ShakyGround works properly and the choice of the parameters has been suitable. Since the time series and response spectra are written as plane ASCII files it will be easy to transport them to other sophisticated data processing and visualization programs. Choosing "View Results" ShakyGround creates a screen as shown below, where the user can scroll the written seismograms and response spectra one by one. Note that the accelerograms can be visualized together with the velocity, displacement and WOOD-ANDERSON seismograms, as shown in the figure. Choosing a seismogram length different than the one proposed as default, the trace can be visualized in their total length or may be zoomed.

The user may decide to see not all the signal types together but choose, for example, to see only accelerograms and velocity seismograms. He can do this clicking the proper boxes in order to get a picture similar to the one reproduced here. The graphical interface for the visualization of the standard out as well as the single seismograms and reponse spectra allows the editing of the figures in a manner that they can be directly imported in other documents. This is extremely useful for the preparation of publications and expertises since many intermediate steps of data and graphical processing are avoided. ShakyGround thus becomes a truly interactive tool in environments based on WINDOWS operating systems.
