Due to knowledge that future quakes are likely to occur, various measures have had to be put into places.
Earthquake simulations are run to see the panic which would occur in the real situation. People can practice organising emergency services for the situation. They are also to see how children react. Lots of screaming and running around.
The emergency services are being trained to act as best they can, by staying calm instead of running around, for instance.
The earthquake has had the greatest effect on the poor long term.
Even before the earthquake, there were large inequalities. The earthquake worsened this.
Half of the population was below the poverty line; after the earthquake, this rose to 80%.
