In Sudoku Earthquake we take a normal 9 x 9 Sudoku puzzle and shake it up.
In each puzzle we've placed a jagged "fault line" of from eight to fourteen spaces zig-zagging from one edge of the puzzle to another. The digits that appear along the fault line are listed below the puzzle. In addition to normal Sudoku rules, you also need to place each of the digits listed for the fault line somewhere along it.
