Most of what we know about the interior of the Earth comes from the study of seismic waves from earthquakes. These waves contain vital information about the internal structure of the Earth.

However, their task is difficult: they need to wait for an earthquake to record data, and when this happens, it only provides information in a piecemeal manner; the data is restricted to a tiny region and most of the time, it’s impossible to distinguish weaker echoes from noise.

A research team recently used a novel algorithm called the Sequencer that was initially developed to find interesting trends in astronomical datasets and revealed structures deep inside the Earth, paving the way towards a new map showing what Earth’s interior looks like. Using the technique, scientists analyzed thousands of seismograms, or records of vibrations of the ground following an Earthquake, collected over the past 30 years.

The algorithm aided scientists in parsing through thousands of seismograms for echoes to create a new map showing details of the Earth’s mantle, just above the liquid iron core, at a depth of 3,000 kilometers.
