Known simply as “P’ (P-prime),” the paper suggested a new discontinuity in the seismic structure of the Earth, now known as the Lehmann discontinuity, a region that divides the core into inner and outer parts.

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 … Web26 de mar. de 2024 · The measurements of seismic waves taken by different observatories around the globe, however, just didn’t add up mathematically.
