what features are associated with subduction zones?
Since this is not my area of expertise, I searched Google under the key words "subduction zones" to get this:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
Subduction zones are a tectonic boundary where two lithospheric plates converge, and one plate is forced beneath the other into the Earth's mantle. They are characterized by several distinct features:
1. Trenches: Subduction zones often have deep oceanic trenches, which are long, narrow depressions on the seafloor. These trenches form where the overriding plate bends and descends into the mantle.
2. Volcanic Arcs: Subduction zones are commonly associated with volcanic activity. As the subducting plate sinks into the mantle, it releases water and other volatiles, which can cause melting and the formation of magma. This magma then rises to the surface, creating a curved line of volcanoes known as a volcanic arc.
3. Earthquakes: Subduction zones are seismically active regions, prone to frequent and powerful earthquakes. These earthquakes occur as a result of the immense stress caused by the plates shifting and interacting along the subduction boundary.
4. Compression and Deformation: Subduction zones involve the compression and deformation of the lithosphere due to the converging plates. This process can lead to folding, faulting, and the creation of mountain ranges on the overriding plate.
To understand these features associated with subduction zones, one can study geology, seismology, and plate tectonics. Geological surveys, satellite data, and seismic monitoring can provide valuable information about the locations and characteristics of subduction zones worldwide. Scientific literature, textbooks, and online resources from reputable sources can offer detailed explanations about subduction zone features and the underlying geological processes.
