New research from Cornell and the Smithsonian Institution deepens the geological understanding of Earth’s continents by testing and ultimately eliminating a popular hypothesis about why continental an...
Earthquakes are notoriously hard to predict, and so too are the usually less-severe aftershocks that often follow a major seismic event.
Nearly 175 community members joined a town forum Nov. 3, held in person and online, to hear updates on the Cornell University Borehole Observatory – known as CUBO. The observatory represents a major s...

2022年8月29日至9月2日，中国-巴基斯坦地球科学研究中心（以下简称“中巴中心”）联合中国地震局地球物理研究所在北京举办了中-巴地震监测与防震减灾技术培训班。
Cornell is one step closer to determining the feasibility of using deep geothermal energy to heat the Ithaca campus.
Swelling colloids – mixtures, such as milk and paint, in which particles are suspended in a substance and which can grow up to 100 times larger under certain temperatures – could be used to fix flow p...
By examining earthquake models from a fresh perspective, Cornell engineers now show that the earthquake fracture energy – once thought to relate to how faults in the Earth’s crust weaken – is related ...

Major environmental events write their own headlines. With loss of life and crippling infrastructure damage, the aftershocks of earthquakes reverberate around the world — not only as seismic waves, bu...
When an 8.2-magnitude earthquake struck off the coast of Chignik, Alaska, on July 29, geophysicist Geoffrey Abers did the logical – if not simple – thing.
He raced to Alaska with a group of collabora...

23 March 2007，A 3.8 billion-year-old sequence of rocks from Greenland is helping scientists pinpoint when the Earth's plate tectonics system kicked into gear, according to new research in the 23 March...
15 March 2007，All tectonic activity on Earth is driven by subduction zones, where one plate is sucked underneath another into the Earth's mantle. Now, for the first time, a team led by Wouter Schellar...
March 15, 2007，Tiny earthquakes called non-volcanic tremors recently discovered in fault zones from California to Japan are generated by slow-moving earthquakes that may foreshadow catastrophic events...
