The Beijing Anomaly is a seismic wave anomaly in the Earth's mantle, from ~700-1400 km depth, characterized by relatively high attenuation and decreased sound speed. Seismic waves are Waves that travel through the Earth, most often as the result of a tectonic Earthquake, sometimes from an Explosion EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 The mantle is a part of an Astronomical object. The interior of the Earth, similar to the other Terrestrial planets, is Chemically divided It is centered beneath northern China, just northwest of Beijing.

The seismic properties of the anomaly are similar to those of the asthenosphere, which contains water absorbed from subducting slabs. The asthenosphere (from an invented Greek a + ' sthenos "without strength" and Greek word σφαίρα (sphera meaning globe is the In Geology, a subduction zone is an area on Earth where two tectonic plates meet and move towards one another with one sliding underneath the other The discoverers of the anomaly, Jesse Lawrence of Scripps and Michael Wysession of Washington University, propose that it has a similar water content, from subducting lithosphere from the Pacific plate. Scripps Institution of Oceanography (sometimes referred to as SIO, Scripps Oceanography or just Scripps) in La Jolla California, is one of the The lithosphere (IPA, from the Greek λίθος for "rocky" + σφαίρα for "sphere" is the solid outermost shell of a rocky Planet. The Pacific Plate is an oceanic Tectonic plate beneath the Pacific Ocean. This would imply that the amount of water in this region of the mantle is comparable to that in the Arctic Ocean (although the water content is no more than 0. The Arctic Ocean, located in the Northern Hemisphere and mostly in the Arctic north polar region is the smallest and shallowest of the world's five major 1% by volume). Other possible causes of the anomaly include small-scale chemical heterogeity and abnormally small particle size. ^[1][2]
