Why
The research confirms that deep earthquakes can occur within Earth's mantle in continental settings, challenging previous assumptions about seismic activity at such depths and conditions.
The Frontline Impact
How this affects you
This discovery validates the existence of continental mantle earthquakes, a rare type of seismic event that occurs much deeper than previously thought possible, and suggests a new way to understand the interaction between Earth's mantle and cratons.
