Do Earthquakes Have a ‘Tell’?（图）
Earthquakes Tell
2017/10/25
Researchers have long had good reason to believe that earthquakes are inherently unpredictable. But a new finding from Northwestern University might be a seismic shift for that old way of thinking.An ...
In the past 540 million years, the Earth has endured five mass extinction events, each involving processes that upended the normal cycling of carbon through the atmosphere and oceans. These globally f...

Earthquake Triggers Slow Motion Quakes New Zealand
2017/9/20
Slow slip events, a type of slow motion earthquake that occurs over days to weeks, are thought to be capable of triggering larger, potentially damaging earthquakes. In a new study led by The Universit...

A University of Oklahoma geophysics professor, Xiaowei Chen, details the foreshock activities leading up to the Pawnee earthquake, and highlights the complicated relationship between seismicity and wa...
Study finds Earth’s magnetic field ‘simpler than we thought’
Earth’s magnetic simpler than we thought
2017/7/24
Scientists have identified patterns in the Earth’s magnetic field that evolve on the order of 1,000 years, providing new insight into how the field works and adding a measure of predictability to chan...
水重量变化触发美加州地震
水重量 美加州地震
2017/6/20
水有力地塑造了美国加利福尼亚州——厄尔尼诺带来的降雨使该州洪水泛滥，严重的干旱则将其蒸干。如今，一项最新研究表明，水或许还扮演了另一重角色：触发地震。
刚从加州大学伯克利分校博士毕业的地球物理学家Christopher Johnson和同事收集了来自由661个散布在加州的GPS传感器构成的网络的数据。这些组件敏感到足以探测出水的重量、地下水开采、潮汐和其他因素导致地面何时上升或下降了几毫米。随后...

Understanding slow-slip earthquakes in subduction zone areas may help researchers understand large earthquakes and the creation of tsunamis, according to an international team of researchers that used...
Seasonal rain and snow trigger small quakes on California faults（图）
Seasonal rain snow small quakes California faults
2017/7/21
California’s winter rains and snow depress the Sierra Nevada and Coast Ranges, which then rebound during the summer, changing the stress on the state’s earthquake faults and causing seasonal upticks i...
