The fault zone location computer programs I am presently working with point mainly to longitudes. They do not do very well with latitudes. My present theory is that this has something to do with how the sun and moon gravities exert strain on the Earth’s crust. Solid Earth Tide and ocean tide crests and troughs for example are lines which run largely north and south.

Some fairly strong signals were detected on 2004/07/11. And my Data.html Web page has been updated.
