Continental Mantle Earthquakes Mapped

Researchers from Stanford University have created the first global map of rare continental mantle earthquakes. The study highlights deep seismic activity occurring beneath the Earth’s crust.

Continental Mantle Earthquakes:

Dimension	Key Details
Depth Range	Occur more than 80 km below the Mohorovičić discontinuity
Comparison with Crustal Earthquakes	Most earthquakes originate in the Earth’s crust at depths of about 10 to 29 kilometres
Moho Definition	Mohorovičić discontinuity separates the crust from the warm, semi-solid mantle
Surface Impact	Do not cause serious shaking at the surface
Scientific Significance	Provide insights into earthquake origins and the internal structure of the Earth
