The M6.3 February 22nd Earthquake caused exceptionally violent shaking in Christchurch. The motions recorded within the city are amongst the strongest ever recorded anywhere: over twice the acceleration of gravity at the CanNet/GeoNet instrument at Heathcote Valley School and close to 1g downtown. Several factors combined to make the shaking especially severe in the eastern hill suburbs, the eastern suburbs of Christchurch and the central city area.
