Massive Solar flares have been link to a phenomenon known as “Sunquakes” These unimaginable quakes that coincide with solar flares generate massive amounts of radiation and particles from the Suns volatile surface. The flares or mass coronal ejections, are responsible for the Northern Lights or Aurora Borealis seen over the skies of the Northern hemisphere of late.
The ejections can cause interference with electronic equipment. The Sun is said to have a 12 year cycle of Solar Storm intensity. The next peak in Solar activity is in 2012. (according to NASA)
Powerful earthquake-like events on the sun’s surface, called sunquakes, can be set off by huge belches of charged particles from the solar atmosphere, scientists say.
Researchers had previously linked sunquakes to solar flares, eruptions on the sun that can send powerful bursts of x-rays, ultraviolet light, and matter into space. On February 15, 2011, researchers spied two sunquakes and a solar flare that occurred around the same time—but the flare wasn’t hot enough to have spawned the seismic waves.
“The heat and radiation from solar flares is thought to drive a pressure wave to the surface, like thunder from a lightning bolt. But for this February 15th event, it wasn’t like that,” said Sergei Zharkov, a space scientist at University College London, who presented the new findings about sunquakes last month at the 2012 National Astronomy Meeting in Manchester, U.K.
Instead it appears the February sunquakes were linked to a coronal mass ejection, or CME, a huge cloud of charged solar particles that erupted from the sun’s upper atmosphere.
“This is the first time we’ve seen a sunquake associated with a coronal mass ejection,” Zharkov said. “It’s the first clear counterexample.”
