Summary:
On July 23, 2012, a huge magnetic storm propelled by two nearly simultaneous coronal mass ejections on the sun plowed through Earth’s orbit. Luckily, Earth was on the other side of the sun at the time. Had the outburst hit Earth, however, it would have rivaled the largest magnetic storm to strike Earth in recorded history, possibly wreaking havoc with the electrical grid, satellites and GPS.
 
Earth dodged a huge magnetic bullet from the sun on July 23, 2012.

 

According to University of California, Berkeley, and Chinese researchers, a rapid succession of coronal mass ejections — the most intense eruptions on the sun — sent a pulse of magnetized plasma barreling into space and through Earth’s orbit. Had the eruption come nine days earlier, it would have hit Earth, potentially wreaking havoc with the electrical grid, disabling satellites and GPS, and disrupting our increasingly electronic lives.

Summary:  A new study suggests that the magma sitting 4-5 kilometers beneath the surface of Oregon’s Mount Hood has been stored in near-solid conditions for thousands of years, but that the time it takes to liquefy and potentially erupt is surprisingly short — perhaps as little as a couple of months.
