We estimate short-period spectral level A, fmax, and Q-value for path of outerrise, intraslab and intetplate earthquakes in the Tohoku district using spectral inversion methods. Q-value of outersise eathquakes is remarkably high in the high frequency range. A of outerise earthquakes are consistent with A of previous reverse-faulting interplate earthquakes. A of normal-faulting earthquakes around the plate boundary are large and comparable with intraslab earthquakes. A of intraslab and outerrise earthquakes are dependent on focal depths. fmax has no dependency on seismic moments nor fault types and the average fmax is 11 Hz. We also develop the attenuation relation of response spectra, peak ground acceleration and peak ground velocity for outerrise earthquakes.
