Making a 3D map in the Earth's heart, revealing the path of lava

By tracking the path of 273 strong seismic events over the past 20 years, scientists at UC Berkeley have for the first time created a 3D map of the structure inside the Earth.

By tracking the path of 273 strong seismic events over the past 20 years, scientists at UC Berkeley have for the first time created a 3D map of the inner structure of the Earth and that explains the magma due to Volcanic eruptions from where there are.

Scientists have created 3D maps in the heart of the Earth

We all know that when volcanoes are active, magma will erupt 'from the ground' to the surface. But it is not yet known how the crater can be linked to the core of the lava pouch 2900km below the surface of the Earth. And more importantly, they learned that most lava flows do not go straight from the bottom up , but originate from '2 main sources' and spread out over the ground at volcanic hotspots.

As can be seen from the map (in the video), the two red areas are the two sources of Earth's lava. It is located below the Earth's crust and above the iron core. This high-detail map shows not only a network of hotspots on the planet, but also the path of 1000km long dams stretching from 600 to 1000km, five times wider than the previously predicted. These lava flows have a temperature of 400 degrees Celsius higher than the surrounding rock layers.

The 1800-mantle beam section is located below the Pacific Ocean and the network is linked to terrestrial volcanic hotspots.

The researchers admit that this map is still not perfect because there are still many volcanic hotspots that are not listed. However, this is a huge step forward, increasing the knowledge of lava flows which is still a mystery to previous geologists. The team hopes to produce a more detailed version with the help of gravity-sensing satellites.
