CMEs Galore

Coronal mass ejections were popping out from the Sun at a pace of two per day on average (Apr. 18-23, 2013). We counted ten CMEs for the five days, but some of the eruptions were complex and difficult to differentiate from one another. Almost all of them blew particles out to the left, most of them probably originating from the same active region. These were taken by the STEREO (Ahead) spacecraft's coronagraph, in which the black disk blocks the Sun (represented by the white circle) so that we can observe the fainter features beyond it.

There's been a connection made between certain types of earthquake activity and CME's. New "Sunquake" Trigger Found: Huge Solar Belches

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. (See video: "Solar Flares Cause 'Sunquakes.'")

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."

You are a bit out of date I'm afraid:

Many have wondered whether solar activity can be linked to earthquakes, but a recent study found no direct relationship between the two.

Scientists assembled historical records of the Sun’s interaction with Earth, looking at sunspots, solar wind, and magnetic storms. They then compared these with historical records of earthquake occurrence. They found no significant pattern between solar activity and more or larger earthquakes. There is no demonstrated way to use space data to predict future earthquakes.

It was a connection between sunquakes and CME's, not Earthquakes..

Fair enough, but that is NOT what you said:
