Well, Steve has been experiencing a LOT of after-shocks, some of which are still big enough to move things around and I found I had to grab hold of my cup of tea to stop it shaking onto the floor last night. In fact these after-shocks are still opening up new cracks in roads and causing buildings to fall.
As for my height position, I have run a few surveys but I'm getting varying readings and I wonder if the after-shocks are messing up the survey results. The latest one which was during a fairly stable period was 6.8 MSL. The mast could have sunk a bit or even this whole area could have done as I live on reclaimed marsh-land. My Mothers 3 year old house looks like it has sunk a bit at one and and risen at the other, ie. it looks like it has tipped slightly as her house is built on a concrete pontoon. It wouldn't surprise me if they adjust the height of MSL but I would have thought they would have moved it the other way in an attempt to forestall fears of the effects of Global Warming.
