Thanks. A friend and I went through the cordon this afternoon to look at the complex - looks like the problem is the combination of severe liquefaction and a seriously damaged church in close proximity to the houses, rather than damage to the house itself. I am now making lists of things to grab within selected time limits (I always wanted to win one of those 5 minutes with a trolley in a large department store competitions, but I think my priorities will be slightly different this time)
