Scientists have discovered that sunquakes are caused by huge eruptions of magnetic field and charged particles in the solar system.

A study led by UCL’s Mullard Space Science Laboratory has shown for the first time that sunquakes, which are powerful earthquakes caused on the sun’s atmosphere can be produced during eruptions of magnetic field and charged particles, as the immense magnetic structure blasts off into the solar system.

According to royal astronomical society, the first observation of a sunquake was reported in the late 1990s. Researchers then believed that solar flares alone caused sunquakes. But now the new study has shown that eruptions of charged particles known as coronal mass ejections are also able to produce sunquakes.

The authors studied an eruption that took place on 15 February 2011 and found that sunquakes that were triggered by magnetic field were 1,000 times more powerful than the Great East Japan Earthquake that struck in March 2011.

It was found that the sunquakes were triggered at the two ends of the erupting rope of Read more…
