We propose a method of calculating seismic intesities by using response spectra in various period ranges. In the original JMA scale, weak, middle and strong ground motions are measured by human body sense and indoor objects motions, moderate damage to buildings, and heavy damage to buildings, respectively. These indices correspond to ground motions in period ranges of 0.1-1s, 0.5-1s and 1-2s. We then formulate low, middle and high intensities with average response spectra in the period ranges. We also propose an algorithm to synthesize these intensities into a single instrumental seismic intensity.
