By measuring small changes in the magnetic field, scientists have historically observed the core flowing mainly westwards. But in 2010, it unexpectedly changed direction deep beneath the Pacific Ocean and started moving strongly eastwards. The reasons for this unexplained reversal in the flow of molten material are still a mystery but satellites, including ESA\u2019s Swarm and CryoSat, provided data that has now been analysed and published.<\/p>\n<p>The study, published in the <i>Journal Studies of Earth\u2019s Deep Interior<\/i>, analyses both ground observations and satellite data between 1997 and 2025. The video shows the large scale of flow in the molten core between 1997 and 2025. The overturn of the flow below the Pacific and the main stable structures of the flow have been isolated. Each arrow indicates the movement of the core liquid horizontal to Earth\u2019s surface.<\/p>\n<p><b>Read full story:<\/b> Insights into Earth\u2019s molten outer core from space<\/p>\n<\/p><\/div>\n<p>\t\t\t<label style=\"display: block; font-size: 0.9em; color: #8197A6; margin: 3rem 0 -1rem 0;\">Embed code<\/label><br \/>\n\t\t\t\t\t\t\t<textarea rows=\"4\" cols=\"60\"><iframe loading=\"lazy\" title=\"Change in Earth\u2019s molten core flow 1997\u20132025\" width=\"1110\" height=\"624\" src=\"https:\/\/www.youtube.com\/embed\/adcbctPjPb8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/textarea><\/p><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Videos\/2026\/05\/Change_in_Earth_s_molten_core_flow_1997_2025?rand=772187\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The molten core, which swirls about 2200 km beneath our feet, generates Earth\u2019s geomagnetic field as it moves.
