Shadow Zone

A seismic shadow zone is an area of the Earth's surface where seismographs cannot detect an earthquake after its seismic waves have passed through the Earth. When an earthquake occurs, seismic waves radiate out spherically from the earthquake's focus. The primary seismic waves are refracted by the liquid outer core of the Earth and are not detected between 104° and 140° (between approximately ) from the epicenter. The secondary seismic waves cannot pass through the liquid outer core and are not detected more than 104° (approximately ) from the epicenter. P waves that have been converted to s-waves on leaving the outer core may be detected beyond 140 degrees.

Shadow Zone is the third album by the band Static-X, released on October 7, 2003. Marked by many personnel and stylistic changes, the album sports a much more melodic sound than any other work in their catalog, while still staying in the confines of their industrial metal and nu metal sound.
