Shows the face of a man with a large tear rolling down his cheek ; in the tear is the word 'Christchurch'. Context - On 22 February 2011 at 12:51 pm (NZDT), Christchurch experienced a major magnitude 6.3 earthquake, which resulted in severe damage and many casualties. A National State of Emergency has been declared. This followed on from an original magnitude 7.1 earthquake on 4 September 2010 which did far less damage and in which no-one died. Quantity: 1 digital cartoon(s).

At 4.35 a.m. on the 4th of September 2010 Christchurch residents were shaken awake by a magnitude 7.1 earthquake, the largest earthquake to hit urban New Zealand for nearly 80 years. It was a large earthquake. On average the world only has 17 earthquakes a year larger than magnitude seven. Haiti’s earthquake in January 2010 was magnitude 7.1 and Chile’s earthquake in February was magnitude 8.8. Although it was a big quake, Christchurch was lucky. In Haiti’s earthquake over 230,000 people were killed and in Chile 40,000 homes were destroyed. Happily this was not the situation in Christchurch, however the earthquake has caused considerable damage. The challenge for the Landscape Architecture community is to contribute to the city’s reconstruction in ways that will not only fix the problems of housing, and the city’s urban, suburban and neighbourhood fabric but that will do so in ways that will help solve the landscape problems that dogged the city before the earthquake struck.

Surface rupture of the previously unrecognised Greendale Fault extended west-east for ~30 km across alluvial plains west of Christchurch, New Zealand, during the Mw 7.1 Darfield (Canterbury) earthquake of September 2010. Surface rupture displacement was predominantly dextral strike-slip, averaging ~2.5 m, with maxima of ~5 m. Vertical displacement was generally less than 0.75 m. The surface rupture deformation zone ranged in width from ~30 to 300 m, and comprised discrete shears, localised bulges and, primarily, horizontal dextral flexure. About a dozen buildings, mainly single-storey houses and farm sheds, were affected by surface rupture, but none collapsed, largely because most of the buildings were relatively flexible and resilient timber-framed structures and also because deformation was distributed over a relatively wide zone. There were, however, notable differences in the respective performances of the buildings. Houses with only lightly-reinforced concrete slab foundations suffered moderate to severe structural and non-structural damage. Three other buildings performed more favourably: one had a robust concrete slab foundation, another had a shallow-seated pile foundation that isolated ground deformation from the superstructure, and the third had a structural system that enabled the house to tilt and rotate as a rigid body. Roads, power lines, underground pipes, and fences were also deformed by surface fault rupture and suffered damage commensurate with the type of feature, its orientation to the fault, and the amount, sense and width of surface rupture deformation.

After the magnitude 7.1 earthquake struck Canterbury on 4 September 2010, most media reports claimed that no lives had been lost. But In fact, this first earthquake killed at least 3000 chickens, eight cows, one dog, a lemur and 150 aquarium fish. University of Canterbury associate professor Annie Potts, along with co-author Donelle Gadenne, wrote Animals in Emergencies: Learning from the Christchurch Earthquakes, revealing what happened to the animals during and after the series of quakes. Annie Potts will give a public lecture, 'Animals and natural disasters: Learning from recent earthquakes', on Thursday 16 March, 7pm at UC Ilam campus, Christchurch.

Went for a drive down to South New Brighton/Southshore after work today to see what interesting birds I could find on the Estuary (godwits, skuas, terns etc), but passing Jellico Street, I saw this.
