If I have to guess, it would be that the below Indonesia (where the bulge is according to the article) there is more radiative cooling happening either due to a thinner crust or higher concentration of more thermally conductive elements in the inner and outer core/mantle/crust. These effects can be localized because the soup from which the Earths&#x27; insides were made was &quot;liquid&quot; to a point and so an even mix of elements is highly unlikely even after…</p><p><a href="https://hackerpaper.kaipfister.de/p/0709.3333/">Paper and discussion history</a>.
