Inside Science 145, “Seeing with seismics”, incorrectly describes the Moho as
the boundary between the Earth’s core and mantle
(Â鶹´«Ã½, 10 November).
The Moho is in fact the boundary between the Earth’s crust and mantle, some
2800 kilometres above the core/mantle boundary.
Also: In our article “Sound defence”
(17 November, p 24)
we stated that a non-lethal acoustic weapon was being developed by American
Technologies. The company name is in fact American Technology Corporation.
