At ocean-ocean convergences, one plate usually dives beneath the other, forming deep trenches like the Mariana Trench in the North Pacific Ocean, the deepest point on Earth. These types of ...

This oceanic trench was created by a dramatic geological process called subduction—where one massive slab of Earth’s crust (the Pacific Plate) slid under a smaller one (the Mariana Plate). This ...

This volcanic arc delineates the boundary between the Pacific and North American tectonic plates. A subduction zone, composed of the deep Aleutian Trench coupled with a landward line of volcanoes ...

and earthquake epicenters along the boundaries where the plates meet, called fault lines. The Ring of Fire is home to the deepest ocean trench, called the Mariana Trench. Located east of Guam ...

A study found that tectonic plates beneath the Chishima Trench are not slipping past each other but appear to be locked ...

A five-year study of the Chishima Trench, which runs parallel to the east coast of Hokkaido about 150km (93 miles) offshore, ...
