Abstract
The Mw 7.1 New Zealand earthquake was the largest earthquake in New Zealand in 60 years and occurred in the sparsely populated Fiordland region of New Zealand. The earthquake caused no deaths and only minor damage in the town of Te Anau, although it was felt through out most of the south island of New Zealand. Surprisingly, it was felt in Sydney, 1800 kilometre away, with some people evacuating buildings. People in Sydney did not feel body or surface waves but felt the T phase from the event. Human perception of a T phase is very rare, with the 1977 Mw8.1 Tonga event being felt in Tahiti 2600 km away (Talandier and Okal 1979), being one of the few well documented instances. The Sydney recording of T phase, whilst larger than the body waves, would still be considered weak motion and not normally felt. I suggest that for someone to have felt this event required the coincident of several factors which enhanced the resulting shaking.
