About Continental Mantle Earthquakes:
- These are seismic events which originate in the mantle beneath continents.
- Origin: These earthquakes often occur more than 80 km below the Mohorovicic discontinuity (boundary between the crust and the mantle).
- Impact: They are too deep to cause much shaking or danger at Earth's surface.
- Occurrence: They occur worldwide but are regionally clustered, particularly beneath the Himalayas in southern Asia and the Bering Strait between Asia and North America.
- Significance: The new map will help scientists learn more about the mechanics of mantle earthquakes.
What is Mohorovicic discontinuity?
- It is the boundary lying between the crust and the mantle of the earth across which seismic waves change velocities.
