It probally started because New Zealand is on a fault line so there is alot of activity so one plate dropped or rose and sent large wavs across the land hitting Napier.
yes the Hawkes bay earthquake is the some as the Napier earthquake
The Napier-Hastings fault. Its' a blind fault and only ruptured he surface along a 15km stretch of the fault.
It is Napier and Hastings who were involved of course
no
An earthquake
not likely
yes it was
1931
they did nothing
the earthquake happened in 1931
the cost of the repairs in the 1931 earthquake was equal to the cost of repairs in the napier earthquake hope this helped ;)
there were 525 after shocks two weeks after the amin earthquake
