Most earthquakes on Earth start in the shallow, brittle part of the planet. However, there are several regions where earthquakes happen deep in the mantle. Where are these regions? Why do these earthquakes get so deep? In this week’s blog post, Ayako Tsuchiyama from the Massachusetts Institute of Technology (MIT) takes us on a journey into the mysterious world of deep earthquakes. Growing u ...[Read More]
