I just realised that yesterday was anniversary of the Kobe earthquake in 1995. Strange I yesterday happened to write about Japan. Coincidence, but still.
This is an interesting article commemorating the disaster, with stuff I never heard of, but important insight, also for future disaster relief. I did visit a friend of a friend who was a wheelchair user and she lived in one of the newly constructed temporary cube like shelters. It was not adjusted at all for a person with disability. She had help from volunteers.
As for more vulnerable categories, a professor I knew very well said no university teachers had died, many students had. As many live in old or cheap houses on soft ground. A figure I heard was over thirty. But I have no data on paper to confirm this. Limited economic resources usually increases the risk of disaster hitting harder.
28 years! That is a quite long time.
