Geogiga Microtremor 7.0 - Microtremor Observation Analysis Software

Geogiga Microtremor uses the spectrum analysis to get the predominant period and frequency of a site from ground motions. The amplitude or power spectrum and H/V ratio can be plotted together.

Main Features:

Frequency filter including Butterworth and Ormsby filters with the option of band pass, low pass, high pass, band reject, and notch
Undo/Redo multi-step operations on seismic data
QC time segments
Analyze amplitude or power spectrum
Display H/V ratio
Output predominant period and frequency
Support SEG-2, SEG-Y, and other data formats
Display seismic data with many controls
Print and save data image
