Long-period earthquake ground motion
WebHanks (1975) recovered 234 components of long-period ground motion in the source region of the 1971 San Fernando earthquake (MW=6.6), and the neighboring Los Angeles basin in California. He coined the term “long-period strong ground motion” in this paper (Zama 1993). Long-period ground WebAn earthquake motion is the shaking motion on the ground surface, and each earthquake motion has its own dominant period. Generally, the period of an earthquake motion is classified in Japan as follows; approximately, between 0.5-1.0 seconds is short period, between 1.0-2.0 seconds is slightly short, between 2.0-5.0 seconds is slightly …

The work described in this paper is part of the group project “Fundamentals of Earthquake Engineering for Hong Kong”, which is financially supported by the Hong Kong Polytechnic University. WebReal earthquakes, of course, have finite duration and a range of frequencies, and therefore as expected the ratios of spectral to ground-motion peaks are much less than 10. Neverthe-less, it seems intrinsically more probable that the ground-motion peaks should be related to the spectral peaks than to spectral values at a fixed period.
