   FFoorrmmaatt::

        A dataframe with 182 observations on 5 variables.

         [,1]     event        numeric      Event Number
         [,2]     mag          numeric      Moment Magnitude
         [,3]     station      factor       Station Number
         [,4]     dist         numeric      Station-hypocenter distance (km)
         [,5]     accel        numeric      Peak acceleration (g)

   DDeessccrriippttiioonn::

        This data gives peak accelerations measured at various
        observation stations for 23 earthquakes in California.
        The data have been used by various workers to estimate
        the attenuating affect of distance on ground accelera-
        tion.
