California's tectonic stress has reached record level, earthquake model reveals
California's tectonic stress has reached record level, earthquake model reveals Gaby Clark Scientific Editor Robert Egan Associate Editor Earthquakes usually occur along fracture zones in Earth's crust, where large tectonic plates slide past one another and become locked. Stress builds up over long periods and is suddenly released in the form of an earthquake. In Southern California, the San Andreas and San Jacinto faults are among the most significant of these zones, accommodating most of...
Earth has a mysterious triple symmetry that may influence its climate
A line that runs through Africa, Europe, Alaska and both poles divides Earth into two halves that reflect the same amount of light – and this newly discovered symmetry may play a critical role in the planet’s climate. It was previously known that the northern and southern hemispheres have almost equal reflectivity, or albedo, but Jianhao Zhang at the National Oceanic and Atmospheric Administration in the US and his colleagues have now uncovered a second line of symmetry along the 27° east...
