Foreshocks predict earthquakes!

      

After a destructive earthquake, scientists sifting through the rumbles that preceded the big event often find foreshocks.
Foreshocks are smaller temblors that strike in the days and hours before a moderate-to-large earthquake. They’re puzzling. Not all earthquakes have foreshocks, and despite decades of effort, no one has successfully found a way to predict earthquakes using foreshocks.

New radiation ring around earth

High above Earth’s surface float two rings of energetic charged particles, and for about four weeks in September, they were joined by a third. The temporary ring may have formed in response to a solar shock wave that passed by Earth, researchers report online February 28 in Science.
The discovery could force scientists to revisit decades of ideas about the structure of the Van
