Christchurch residents are being warned of potential safety risks associated with rock falling from Shag Rock on Sumner Beach.

Large sections of the vertical face on several sides of Shag Rock subsided in the last fortnight and geotechnical investigations indicate there is a significant risk of further such incidents, says City Council Transport and Greenspace Manager Alan Beuzenberg.

"Fortunately, no-one was injured when the rock fell."

He says the recent rock fall was caused by natural erosion, and no doubt compounded by the winter rain, wave attack and frost/ice on the vertical faulted rock face.

"The rock falls are part of the natural weathering of Shag Rock. The Council has been monitoring the potential risks at Shag Rock since 2003 and while rock falls are not unexpected, they can not be predicted."

He says signage is in place warning residents and visitors to the area of the potential risks from rock falls and advising them to keep clear of Shag Rock and not to climb it.

"Council asks residents and visitors that for their own safety they observe the signs and safety precautions which have been put in place."

The Council and ECan are currently discussing options for the future management of the risks.
