Inge Lehmann ForMemRS (13 May 1888 – 21 February 1993) was a Danish seismologist and geophysicist. In 1936, she discovered that the Earth has a solid inner core inside a molten outer core. Before that, seismologists believed Earth's core to be a single molten sphere, being unable, however, to explain careful measurements of seismic waves from earthquakes, which were inconsistent with this idea. Lehmann analysed the seismic wave measurements and concluded … WebSummary The mathematics behind Inge Lehmann’s discovery that the inner core of the Earth is solid is explained using data collected around the Earth on seismic waves and their travel time through the Earth.

WebDanish seismologist Inge Lehmann “the only Danish seismologist,” as she once referred to herself—studied the shock waves and was puzzled by what she saw. A few P- waves, which should have been deflected by the core, were in fact recorded at seismic stations.
WebThe Lehmann discontinuity is an abrupt increase of P -wave and S -wave velocities at the depth of 220 km (140 mi), discovered by seismologist Inge Lehmann. [2] [3] [4] The thickness is 220 km [citation needed]. It appears beneath continents, but not usually beneath oceans, [5] and does not readily appear in globally averaged studies.
