Most trenches are long, narrow and deep,3-4 km (2-2.5 mi) below the surrounding sea floor. The greatest dept anywhere in the ocean is found in the Mariana Trench southeast of Japan. It plunges more thanb 11 km(6.8 mi) below sea level. Frequent earthquakes and volcanic eruptions occur along the trenches.
