With an average of four mini-earthquakes per day, Southern California`s San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the Southern San Andreas fault, according to an article in the journal Nature Geoscience.
"Those minor to moderate events along the San Jacinto [...]

Recent simulated earthquake tests conducted by UC San Diego engineers are expected to lead to retrofit schemes that make historic buildings safer. The structural engineers tested a structure similar to those that were built in California in the 1920s that have masonry-infilled walls and reinforced concrete frames.
Based on data collected from tests performed on the [...]

Ji ShaoCheng of the Université de Montréal`s affiliated engineering school École Polytechnique is part of a team studying last May`s devastating earthquake in China.
On May 12, 2008, at 2:28 p.m., China`s Szechwan province changed forever. In the space of 90 seconds, an earthquake equivalent to 1,200 H-bombs pulverized the earth`s crust for more than 280 [...]

Physics 10: Physics for Future Presidents. Spring 2006. Professor Richard A. Muller. The most interesting and important topics in physics, stressing conceptual understanding rather than math, with applications to current events. Topics covered may vary and may include energy and conservation, radioactivity, nuclear physics, the Theory of Relativity, lasers, explosions, earthquakes, superconductors, and quantum physics. [...]
