Pitcairn hotspot

The hotspot is currently located at Adams and Bounty, which are ~60 kilometers East-Southeast of Pitcairn Island.

This is where material is thought to be sourced from the core-mantle boundary, rising to surface as a localized plume.

Bathymetry records have estimated the volume of erupted lava due to volcanic activity to be about 5900 km3 within a radius of about 110 kilometers.

[3] The larger edifices show much more extensive volcanic activity and a wider range of compositions than the smaller.

[8] Using methods of modeling of lead isotopes, the date set for different rocks around Pitcairn hotspot were estimated to be from 0.6 and 0.7 Ma.
