Recent field investigations were carried out to define the shear wave velocity (VS) profile and site periods across the Canterbury region, supplementing earlier efforts in urban Christchurch. Active source surface wave testing, ambient wave field (passive) and H/V spectral ratio methods were used to characterise the soil profile in the region. H/V spectral ratio peaks indicate site periods in the range of 5-7 seconds across much of the Canterbury Plains, broadly consistent with those based on a 1D velocity model for the region. Site periods decrease rapidly in the vicinity of the Canterbury foothills and the Banks Peninsula outcrops. In Christchurch, the Riccarton Gravels result in a significant mode of vibration that has a much shorter period than the site period of the entire soil column down to basement rock.

Earthquake damage. As a result of the September 2010 earthquake, with further damage from the February 2011 event.

Castle Rock above Heathcote, showing damage (and two very large pieces in the foreground) that came down during the 7.1 quake on 4th September.
Nearly two weeks after the 7.1 earthquake, and a week after demolition started, this is the end of The Valley Inn in Heathcote.
