Being on the hill must have been rough. Have a friend who moved to the city a few years ago and was super excited to find a bit of bare land up on the hill with a great view into the estuary to build a house on - explained why it was bare, didn’t seem to deter him.
It’s interesting how the geography affected things - another friend had a batch in Akaroa on the other side of the peninsula that barely felt the quakes - theory being the peninsula is a dead volcano, so it’s mostly really spongy basalt that effectively acted as a dampener and absorbed most of the energy
The MAD doctrine aims to make the intentional use of nukes in war unworkable, but in doing so makes their accidental use due to mishap, misunderstanding or miscommunication much more likely, and the more people that are party to the MAD doctrine the more likely accidents are.
You don’t need to look very hard to find examples of cases where billions of people would have been killed if not for people choosing to ignore doctrine even when the information they had at hand said that they should use their weapons
