From My Little Blue Window By Elvis Costello Well, I was a gloomy soul Never thought I see a brighter day The dark interior Blows those silver clouds away 'Til now this was my view But I'm counting on you How am I ever going got make you see? Nothing in this ugly world comes easily I want you to be... My lovely hooligan Come by and...

Known by the locals as the "Owner's House" of the large Farnley Brick and Tile Works which was situated nearby. Established by the Austin brothers in 1863 the brickworks were named after the town of Farnley in Yorkshire England, from where the family had come. I remember the brickworks as a child and I think they were demolished in the 1970's. V...

The Avon-Heathcote Estuary is of significant value to Christchurch due to its high productivity, biotic diversity, proximity to the city, and its cultural, recreational and aesthetic qualities. Nonetheless, it has been subjected to decades of degradation from sewage wastewater discharges and encroaching urban development. The result was a eutrophied estuary, high in nitrogen, affected by large blooms of nuisance macroalgae and covered by degraded sediments. In March 2010, treated wastewater was diverted from the estuary to a site 3 km offshore. This quickly reduced water nitrogen by 90% within the estuary and, within months, there was reduced production of macroalgae. However, a series of earthquakes beginning in September 2010 brought massive changes: tilting of the estuary, changes in channels and water flow, and a huge influx of liquefied sediments that covered up to 65% of the estuary floor. Water nitrogen increased due to damage to sewage infrastructure and the diversion pipeline being turned off. Together, these drastically altered the estuarine ecosystem. My study involves three laboratory and five in situ experiments that investigate the base of the food chain and responses of benthic microalgae to earthquake-driven sediment and nutrient changes. It was predicted that the new sediments would be coarser and less contaminated with organic matter and nutrients than the old sediments, would have decreased microalgal biomass, and would prevent invertebrate grazing and bioturbation activities. It was believed that microalgal biomass would become similar across new and old sediments types as the unstable new sediments were resuspended and distributed over the old sediments. Contact cores of the sediment were taken at three sites, across a eutrophication gradient, monthly from September 2011 to March 2012. Extracted chlorophyll a pigments showed that microalgal biomass was generally lower on new liquefied sediments compared to old sediments, although there was considerable site to site variation, with the highly eutrophic sites being the most affected by the emergence of the new sediments. Grazer experiments showed that invertebrates had both positive and negative site-specific effects on microalgal biomass depending on their identity. At one site, new sediments facilitated grazing by Amphibola crenata, whereas at another site, new sediments did not alter the direct and indirect effects of invertebrates (Nicon aestuariensis, Macropthalmus hirtipes, and A. crenata) on microalgae. From nutrient addition experiments it was clear that benthic microalgae were able to use nutrients from within both old and new sediments equally. This implied that microalgae were reducing legacy nutrients in both sediments, and that they are an important buffer against eutrophication. Therefore, in tandem with the wastewater diversion, they could underpin much of the recovery of the estuary. Overall, the new sediments were less favourable for benthic microalgal growth and recolonisation, but were less contaminated than old sediments at highly eutrophic sites. Because the new sediments were less contaminated than the old sediments, they could help return the estuary to a noneutrophic state. However, if the new sediments, which are less favourable for microalgal growth, disperse over the old sediments at highly eutrophic sites, they could become contaminated and interfere with estuarine recovery. Therefore, recovery of microalgal communities and the estuary was expected to be generally long, but variable and site-specific, with the least eutrophic sites recovering quickly, and the most eutrophic sites taking years to return to a pre-earthquake and non-eutrophied state. changes in channels and water flow, and a huge influx of liquefied sediments that covered up to 65% of the estuary floor.

Text reads 'City's old chimneys are considered the no. 1 earthquake danger'. Below are several angry-looking chimneys which sing 'Chim chim-in-ey. Chim chim-in-ey, chim chim cher-oo! When the big shake's on - we're coming to get you!' Context - Invercargill City council building services manager Simon Tonkin has seen first-hand the massive damage falling chimneys inflicted on homes and nearby vehicles following the massive Christchurch quake, and says that Invercargill's old brick chimneys are the No1 danger to the city's residents and homes if a major earthquake strikes and should be removed if they are not being used.

Maybe it should be titled "Pray Here"! The old church buildings next to the Christchurch Basilica (Cathedral of the Blessed Sacrament) have been demolished and replaced with ANOTHER Wilson's Car Park. Hundreds of sites in the city where buildings have been demolished after the earthquakes have been replaced in the short term by car parks!

"Open Theatre" - The Odeon Built in 1883 and known as the Tuam Street Hall or Theatre and was New Zealand's oldest masonry, purpose built theatre. In 1930, it became the St. James Theatre, It became The Odeon Movie Theatre in 1960. Demolition started in September 2012 after the Christchurch earthquakes of 2010/2011 but seems to have stopped!?
