Japan-Taiwan-New Zealand Seismic Hazard Assessment Meeting


29 November 2023

Papatea Fault rupture – Kaikōura Earthquake, November 2016

Wednesday 29 November to Sunday 3 December 2023

Napier Conference Centre, Ahuriri / Napier, Aotearoa New Zealand

The Taiwan-Japan-New Zealand Seismic Hazard Assessment Meeting is an annual event aimed at sharing research and finding collaboration opportunities between these three tectonically similar countries.

The topics discussed have an applied societal focus for reducing the risk of earthquake disasters.

Aotearoa New Zealand will be holding the 2023 Taiwan-Japan-New Zealand Seismic Hazard Assessment meeting at the Napier Conference Centre.

Ahuriri / Napier is a city located along the active Hikurangi subduction margin in the Hawke's Bay region of the North Island.

The city of Ahuriri / Napier(external link)  was largely destroyed in the 1931 magnitude 7.8 earthquake(external link) and is known for its unusually high concentration of 1930s Art Deco buildings. Napier was selected as the location of this year's meeting for its earthquake history and plate tectonic setting.

As with previous meetings we will run the meeting in conjunction with a 2-day fieldtrip, so delegates can experience some of the Aotearoa New Zealand geology and culture. The fieldtrip will start from Napier on Saturday 2 December and finish in Auckland on Sunday 3 December.


  • General information

    Meeting participants will be asked to arrange their own transport to Napier and from Auckland (if you are not attending the fieldtrip you will need to arrange return transport from Napier).

    In addition, attendees will arrange their own accommodation in Napier. You will require accommodation in Napier for the nights of 28, 29, 30 November and 1 December. Below are links to a number of accommodation options relatively close to the Napier Conference Centre.

    If none of these options suit your requirements, Napier has a thriving AirBNB supply of detached (mostly wooden) houses for rent.

    Travel and accommodation for the fieldtrip will be organised by the conference committee. Meeting participants will be asked to cover the cost of the fieldtrip accommodation via the registration portal.

    There will be a modest registration fee for the meeting that will be set at a level to encourage participation. The fee will be set prior to opening of the registration.
