There are very significant differences between strong and small-moderate earthquakes, for example, the ground motion of small-moderate earthquakes attenuate fasert, transmit a smaller distance and have more high frequency components. The authors use 132 small-moderate horizontal recordings on rock in Europe to study the attenuation relationship. Local magnitudes are between 4 and 6, hypocenter distances are less than 70 km. The authors obtain the attenuation equations for PGA and 5% damp SA at spectra periods between 0.04 and 4 seconds.
