Seismic imaging in northeastern China revealed both the top (X1) and bottom (X2) boundaries of a tectonic plate (blue) that formerly sat at bottom of…
Lava flowing across black rocks. International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the…
2007 – 2018 Global sea level has been rising at a rate of 0.1 inches (3.3 millimeters) per year in the past three decades. The…

Rock-melting forces occurring much deeper in the Earth than previously understood appear to drive tremors along a notorious segment of California’s San Andreas Fault, according…
Since the crystals of microdiamond are finer than 1 micron, they were confirmed by the latest analytical techniques such as Raman spectroscopy, soft X-ray spectroscopy,…

University of Texas at Dallas geoscientists used earthquake data and a computationally intensive technique called a full waveform inversion to create 3D images of the…
Earthquakes send sound waves through the Earth. Seismograms record the echoes as those waves travel along the core-mantle boundary, diffracting and bending around dense rock…
