Microtremor
Microtremor Measurements
Estimate the site predominant frequency using HVSR with a few clicks
Data input
- Load 3-component data
- Support SEG-2, SEG-Y, SEG-D, ASCII, SAF, miniSEED, and other data formats
Data processing
- Frequency filtering with multi-step undo and redo
- Select time segments tapered with Hanning, Hamming, or boxcar window
- Analyze amplitude or power spectrum
- Generate HVSR (horizontal-to-vertical spectral ratio)
Output
- Predominant period, frequency, and amplitude
- Overburden thickness
