At a convergent boundary between oceanic and continental crust where subduction is occurring.
The pronounced submarine feature along the eastern margin of the Nazca Plate that indicates a convergent plate boundary is the Peru-Chile Trench, also known as the Atacama Trench. This deep oceanic trench marks the subduction zone where the Nazca Plate is being forced beneath the South American Plate. The presence of this trench is a clear indicator of the tectonic activity associated with convergent boundaries, characterized by intense geological processes, including earthquakes and volcanic activity.
Trenches such as the Peru-Chile trench are found at destructive (also known as convergent) subductive plate margins where the denser oceanic plate is being subducted beneath the lighter continental plate. Trenches are common at subduction zones.
Some of the major fault lines in the Ring of Fire include the Pacific Plate boundary, which consists of the San Andreas Fault in California, the Japan Trench, and the Peru-Chile Trench. These fault lines are known for frequent seismic and volcanic activity due to the intense tectonic movement along the Pacific Plate and its neighboring plates.
Subduction of nazca plate beneath TE south American plate since nazca plate is an oceanic plate, which means it is more dense than the south American plate, which is continental. Oceanic plates have 3.0g/cm^3 of density. Continental have 2.8g/cm^3 of density. Denser plate always sinks beneath less dense plates :)
A convergent plate boundary.
The Peru-Chile Trench is a convergent plate boundary, where the Nazca Plate is subducting beneath the South American Plate. This subduction zone is associated with frequent earthquakes and volcanic activity.

The Trench and Andes are on the boundaries of the Nazca and South American Plates. Both of those landforms are the result of a subducting Nazca Plate.

The 1960 southern Chile earthquake occurred due to the subduction of the Nazca Plate beneath the South American Plate along the Peru-Chile Trench. This subduction zone is part of the larger Pacific Ring of Fire where tectonic plates meet and seismic activity is common.

Ocean ridges and deep ocean trenches force slab pull and slab push to facilitate plate tectonics. The ocean ridges raise the ocean floor pushing the plate toward the trench, which is lower pulling the plate into the subduction zone.
