Tremors of such force to cause a massive landslide in the canyon, which is located at the bottom of the Cook Strait, 10 km from the coastal areas of the city. Derailment of land just can cause a wave that hit the capital in 12 minutes after the earthquake.
Geologist Joshu Mountjoy indicates that about one in every 100 years in the canyon at the bottom of the Cook Strait is a landslide that moves 50 million cubic meters of rock. However, in the XX century, the region has not happened so strong earthquakes that could cause a tsunami.
