Whose discovery of seismic waves transformed the study of earthquakes?
Quick Answer
Beno Gutenberg is credited with major advances in seismology, including identifying Earth's core boundary in 1914. His work helped make earthquake waves a tool for studying Earth's interior.
The Full Story
German-American seismologist Beno Gutenberg made foundational contributions to understanding how earthquake waves travel through Earth. In 1914, he determined the depth of the Earth's core-mantle boundary, now called the Gutenberg discontinuity, at about 2,900 kilometres. That discovery came from analysing the paths of seismic waves from earthquakes. Gutenberg's work showed that earthquakes are not only destructive events but also probes of Earth's interior structure. His research remains central to modern seismology.
