The study mapped hundreds of deep continental earthquakes, which are rare events that occur at depths of 300-700 km within the Earth's mantle.

Scientists map rare earthquakes deep within Earth’s mantle for the first time
A Stanford-led study has mapped hundreds of rare deep continental earthquakes within the Earth's mantle for the first time. This provides new insights into how earthquakes originate beneath the Earth's crust, which is crucial for understanding the planet's internal structure and dynamics. The findings can help improve earthquake monitoring and prediction capabilities, making it relevant for competitive exams related to science, technology, and disaster management.

Exam-ready takeaways
The researchers used a new method to detect these deep quakes by analyzing seismic waves recorded by global monitoring networks.
The study found that deep quakes are more common beneath continental regions compared to oceanic areas, providing insights into differences in Earth's internal structure.
Deep quakes are thought to be caused by phase transitions in minerals within the mantle, rather than tectonic plate movements near the surface.
Understanding deep quakes can help improve models of the Earth's interior and enhance earthquake monitoring and prediction capabilities.
How to study
Turn news into exam marks
Revise monthly events by exam family instead of reading random updates.
Pair one-liners with mock tests so mistakes become the next revision list.
Keep state job pages, calendar pages and GK packs connected in one path.
