Visualisation of resonant basin response at the Parkway array, New Zealand

Seismograms recorded by a temporary dense seismometer array at Parkway, New Zealand, are displayed in various frequency bands, as moving pictures of the ground motion due to earthquakes, thus improving our understanding of the amplified response of a small alluvial basin. Transverse waves, longitudinal waves and a “cellular mode of resonant response” are seen. The separately available movies are essential for the paper to be appreciated properly.
