The boundaries of the depression approximately coincide with the isobath of 6000 m. The average steepness of the slopes is about 7 °. On the slopes - numerous ledges, terraces, as well as valleys descending to the maximum depth. The epicenter of many strong earthquakes [2] .
It was investigated mainly in the 1950s by Soviet expeditions on the Vityaz vessel.
