High-frequency waves attenuate rapidly and reveal details about shallow rock layers and soil properties. Engineers use response spectra to determine how structures of varying heights will react to specific frequency bands.
Seismic Waves Frequency Research Methodology Overview
Surface Waves: Ground Shaking and Damage Potential Surface waves usually possess lower frequencies, often between 0. Body Waves: Primary and Secondary Motion P-waves, or primary waves, are compressional motions that travel fastest and typically exhibit higher frequencies ranging from 1 to 20 Hz.
The output is often visualized in a seismic spectrogram, which plots frequency against time to reveal how the energy of the wave changes. Rayleigh waves roll along the ground like ocean waves, while Love waves move the ground horizontally in a shearing motion.
Seismic Waves Frequency Research Methodology Overview
S-waves, or secondary waves, move through solids with shear motion and generally produce lower frequencies between 0. High-frequency signals (above 1 Hz) are utilized for near-surface imaging and engineering site assessments.
