Impact on Natural Environments- Gravelly Plains The alluvial (gravelly) plains to the west were the areas most affected by the Sept. 4th Earthquake. The Feb 22nd E.Q had little impact. The Greendale fault trace could be clearly seen from the air as a 29-30km line of cracks, tears and pressure ridges. -Land also one side of the fault was lifted 1-1.5m vertically. -The land also moved 4.5m horizontally -Changes that occurred: streams change course, trees fell over, GPS satellites showed the township of Rolleston had moved 3 metres closer to Darfield. -Shaking caused: new springs, changed water levels in wells, more silt in rivers and streams. Impact on Natural Environments- Gravelly Plains

Hill country- uplift and erosion After the Sept. 4th Earthquake there were small slips, landslides and river sedimentation. The largest earthquake was on the Kaikoura coast., where tonnes of rock and rubble spilled into the sea. Feb 22nd caused 1.5m of uplift along the north eastern side of Port Hills Large landslides and rock falls around Sumner and Redcliffs. Hill country- uplift and erosion

Sandy Environment of the eastern plains. Liquefaction makes sediment behave as liquids. They will flow towards low points like rivers or harbours. Sand, silt and water gushed up to the surface in Kaipoi and CHCH’s eastern suburbs (New Brighton, Avonside, Parklands, Burwood) Large holes appeared on previously flat surfaces, water tables rose, previously dry land turned into swaps.
