You Didn't Feel Continental Mantle Earthquakes, But They Happened. A Lot
A 1979 seismic event was a different kind of earthquake, and it is has intrigued scientists ever since.
A new look at old data has provided some additional answers.
On Feb. 24th, 1979, seismographs recorded a magnitude 3.8 earthquake under Randolph, Utah, located near the Idaho and Wyoming borders.
Yet no one felt a thing and the seismic data made no obvious sense. Because its focal depth was 50 miles below sea level, the hypocenter wasn't in Earth’s crust, it was well into the upper mantle.

How To Overcome Leadership Battles
In times of social rancor and strife, most will fight each other, but societies are saved by those who think about the bigger issue.
There is a lesson humans could learn from wasps. Polistes canadensis wasps are more like China than a democracy, so when their ruler dies, power struggles and social turmoil result. Amidst the violence and chaos, individuals compensate by helping the group rather than fighting each other.
