I was noticing in these pictures that there were still good roads, lots of cars, and electricity towers. What housing is going up to replace these? Isn't it possible to come up with a lighter construction, using foam concrete, steel roofs, paper tubes etc. Could the incremental cost be less than a car, tv set? Of course, in the case of a big landslide, there isn't much you can do, but each village could have a 'safe building' to go to when they feel the foreshocks.
