More fault lines in Hamil­ton

Hamilton Press - - FRONT PAGE - STUFF

Hamil­ton’s not known for earth­quakes, but it’s on top of more fault lines than we knew.

Univer­sity of Waikato re­searchers with echo sounders have found 25 po­ten­tial fault zones in the bed of the Waikato River.

At least four of those might still be ac­tive, Dr Vicki Moon and Dr Willem de Lange say.

One is in north Hamil­ton, around Os­borne Road, and the Kuku­taruhe Fault cuts through Hamil­ton from Tem­ple View to Ro­to­tuna.

Another two are in the south­east­ern Te Tatua o Wairere fault zone - a fault run­ning be­tween Rukuhia and Hill­crest, and a second branch­ing out to­wards Tama­here.

This in­for­ma­tion doesn’t nec­es­sar­ily mean Hamil­ton is likely to get stronger earth­quakes, nor are they more likely, de Lange said.

Ini­tial results say the max­i­mum earth­quake mag­ni­tude for the city would re­main at 6.8.

‘‘but there could be more shak­ing and more dam­age to in­fras­truc­ture such as sew­er­age pipes, roads, and other ser­vices’’.

That would af­fect re­cov­ery ef­forts.

Dr Willem De Lange.
