| Outline of Final Research Achievements |
We continued a dense seismic observation in the northern part of the South Island in New Zealand, and installed 3 new stations around the north-western end of the South Island where no seismic stations are operated. By analyzing recorded data, we obtained the results that support the hypothesis that water upwelling from subducting plates reaches to the lower crust and generates intraplate earthquakes. The Kaikoura earthquake Mw(7.8) occurred within our seismic network on December, 14th, 2016. We installed 4 new stations near the hypocenter of the main shock, and succeeded the maintenance of seismic stations to which accesses are difficult owing to road closed, and obtained valuable data. We estimated detailed hypocentral distributions and stress fields before and after the main shock.
