Glossary

The PGA (Peak Ground Acceleration) denotes the maximum ground acceleration recorded during the seismic shaking by the three components of the seismic station.

The PGD (Peak Ground Displacement) denotes the maximum ground displacement recorded during the seismic shaking by the three components of the seismic station.

The PGV (Peak Ground Velocity) denotes the maximum ground velocity recorded during the seismic shaking by the three components of the seismic station.

Feature of the station indicating proximity to structures which could influence the seismic response of the soil (i.e. Free-field, Close to structure, No information, Inside structure, and Strcture related free-field)

The bearing, relative to north, along which the double-sided pulse in the velocity trace is detected.

Waveform characterized by double-sided pulse in the velocity trace.
