The influence of multiple impedance contrasts on mHVSR site period estimates in the Canterbury Plains of New Zealand and implications for site classification

An experimental study of the fundamental period of vibration of geologic strata above multiple impedance contrasts is presented for the Canterbury Plains, a deep, complex sedimentary basin on the South Island of New Zealand. Microtremor …

Amplification of strong ground motions at Heathcote Valley during the 2010–2011 Canterbury earthquakes: Observation and 1D site response analysis

Abstract The strong motion station at Heathcote Valley School (HVSC) recorded intense ground accelerations (peak value of 1.4 g in horizontal and 2.2 g in vertical component) during the 22 February 2011 Christchurch earthquake. More importantly, …
