Dagny, the neighbors we were on chatting terms with pre-earthquake are doing ok. Can't say for the rest as a natural disaster is apparently not enough to make them sociable
The police say domestic violence incidents are up 50% so yes, much of the population is somewhat stressed.
The house next door already needed to be repiled as a result of the September quake so I would expect that it is damaged further. One further down the street also already had some bad foundation damage and is much worse now but the tenants are staying put as it is impossible to find another rental property, and they still have their jobs.

At least 70,000 people have left the city so far. Many of them will return if their jobs are still available - 50,000 people worked in the inner city area that is currently cordoned off, and businesses are already trying to relocate if they can, or are working out of employee's houses.

I live on the south side of town, a few blocks from the cordoned off inner city area. We got power back on within 12 hours. Some eastern suburbs still have no electricity because the power lines ran underground there and soil liquefaction has caused serious damage to the underground infrastructure. Basically they fixed the easy stuff first, and anything else is going to take a lot longer.
