Seismic Handler (SH) is an interactive analysis program for preferably continuous waveform data. It was developed at the Seismological Observatory
Gräfenberg and is in use there for daily routine analysis of local and global seismic events. In original form Seismic Handler was
command line based, but now an interactive version is available.
Main features
Reading traces from continuous data streams in Steim-compressed
MiniSEED files. Additionally supported formats are event data from GSE, AH and Q (private format of SH) files.
Zoom in and out traces in time and amplitude.
Application of a set of standard filters (simulation filters and
Butterworth filters) on broadband input traces.
Reading phases on original or preprocessed traces.
Determination of signal/noise ratio
Computation of teleseismic beam traces using array-beamforming or FK-algorithm, determination of slowness and back-azimuth of an incoming wavefront.
Location of teleseismic events using global travel time tables based on array methods or relative travel times, determination of focal depth using depth phases
Location of regional and local events using LocSAT program, flexible interface provided for integration of own location programs.
Integration of an own external programs (e.g.: map display, phase diagrams).
Displaying theoretical travel times.
Determination of amplitudes and
magnitudes (ml or mb and Ms).
Saving analysis results into an output text file for further processing.
