Seismic Handler

Main features

• Reading traces from continuous data streams in Steim-compressed MiniSEED files. Additionally supported formats are event data from GSE, AH and Q files.
• Zoom in and out traces in time and amplitude.
• Application of a set of standard 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.
• Displaying theoretical travel times.
• Determination of amplitudes and magnitudes.
• Saving analysis results into an output text file for further processing.
• Supported operating systems: Solaris and Linux

  Additional features

• Rotation of 3-component seismograms
• Particle motion diagrams
• Vespagram-like trace summation
• Trace spectrum display
