The National Institute of Information and Communications Technology (NICT/Japan) reported the collape of the magnetosphere on June 4 and 5th. The magnetosphere is the magnetic field surrounding the Earth that shields us from the effects of geomagnetic storms and other solar emissions. See Wikipedia info http://en.wikipedia.org/wiki/Magnetosphere.
While this field undergoes constant change, this is highly unusual – and caused by prolonged impact by solar winds. One hypothesis (http://www.solartyphoon.com/solar4.htm) is that a total collapse will cause induced current on the Earth's surface measured in the tens or hundreds of volts per linear mile, transferring enormous amounts of heat into the Earth's inner core, and trigger massive earth crust displacement.
