Here's a breakdown:
* Deepest Recorded Earthquake: The deepest earthquake ever recorded was a magnitude 7.9 earthquake that occurred on August 24, 1996, near Iquique, Chile. This earthquake reached a depth of 660 km (410 mi), placing it within the transition zone of the Earth's mantle.
* Other Deep Earthquakes: Several other earthquakes have been recorded at depths exceeding 600 km. Many of these occur within the Pacific Ring of Fire, particularly along the Peru-Chile Trench and the Japan Trench.
Why do deep earthquakes occur?
Deep earthquakes are caused by the collision of tectonic plates. When one plate slides beneath another (subduction), the descending plate experiences immense pressure and friction. This friction generates heat and stress, which can trigger earthquakes at great depths.
Important Note: While deep earthquakes are less common than shallower quakes, they can still be significant. Their effects are often limited to the immediate area, but they can still cause some ground shaking and minor tsunamis.
