Karl Bernhard Zoeppritz was a German geophysicist who made important contributions to seismology, in particular the formulation of the Zoeppritz equations.
These equations relate the amplitudes of Pwaves and Swaves at each side of an interface, between two arbitrary elastic media, as a function of the angle of incidence and are largely used in reflection seismology for determining structure and properties of the subsurface.

San Francisco Earthquake of 1906
The San Francisco earthquake of 1906 was a major earthquake that struck San Francisco and the coast of northern California at 5:12am on Wednesday, April 18, 1906. The most widely accepted estimate for the magnitude of the earthquake is a moment magni...
