Recent research has revealed unexpected geological activity beneath the Midwest and Ohio Valley, suggesting that the North American craton, typically thought to be stable and unchanging, may be undergoing erosion. This study utilized data from over 6,000 seismometers to analyze seismic waves from earthquakes, uncovering evidence that a previously lost geological plate could be extracting rock from the bottom of the craton. The findings challenge the long-held view of cratons as eternal landforms and highlight the dynamic nature of Earth's geology.
Scientists have uncovered surprising evidence indicating that the geological core of North America, a long-lasting craton, may be undergoing erosion beneath our feet.
The research team utilized data from over 6,000 seismometers, revealing that a geological plate might be siphoning rock from the North American craton.
