• The polarity of the peak ground motion parameters is

now displayed.

• The absolute significant (effective) duration is now

computed.

• The cut-off frequency and order of the high-pass

Butterworth filter can be chosen interactively using

Fourier amplitude spectra of the signal and the noise

(estimated from the pre-event portion of the time-

history).

• The units used to display accelerations, velocities and

displacements can be chosen.
