One of The Hot, Dense Blobs Deep Inside Earth Has Been Revealed With New Imaging - ScienceAlert
For the first time, scientists have taken a proper look at an ultra-low velocity zone.
The latest in computational modeling techniques were used to produce the image, techniques applied to a high-frequency signal that was recorded as seismic waves rippled through the ultra-low velocity zone.Better imagery of these deep and mysterious zones should help in that field of research too, and scientists are also studying basalt rock on the surface in Hawaii to look for evidence of core leaking.The study of ultra-low velocity zones is limited in some respects by where earthquakes occur and where seismographs are installed, but the team is keen to apply their high resolution imagery enhancements to other deep pockets of Earth.
