Rockwell said his work highlighted that earthquakes came in clusters. "I would encourage people to say, 'look I'm going to measure how much time it takes me to get from my place or my work place up to higher ground," Orchiston said. "There's so much incredible science going on in this space and for me my interest is in how to translate that into a way that has public good. University of Otago scientist Caroline Orchiston said the science was all about providing a public service. "People normally are just stunned by the fact that they went through a magnitude-9, and you're not thinking about it when you're on the beach that there might be something coming at them," Rockwell said. Visiting San Diego State University professor Tom Rockwell said the first moments following a powerful quake on the subduction zone would be vital to survive a tsunami. "We know from tsunami modelling from a hypothetical earthquake from the Hikurangi subduction zone that the travel times could be very short to the coast, so seven minutes for some of the south Wairarapa coast," Cochran said.Ĭochran said it would take between 10 to 30 minutes to reach Cloudy Bay in Marlborough but Blenheim was not at risk due to being too far inland.Ĭochran was speaking at an international earthquake conference in Blenheim earlier this month, on the anniversary of the Kaikōura quake.
Tsunami modelling of a magnitude-9 rupture on the Hikurangi subduction zone showed people living in coastal communities would not have much time to escape.
