Thanks to the OP for bringing it up to attention on ATS.
Usually, the shockwave from a CME strikes Earth within 15mins of the even to a fews later. It's electrically charged pressure waves alter that of our
Magnetosphere. Much of the time, our Magnetosphere could deflect it, but there were a couple of recorded times it did not, and penetrated through it,
disrupting and interfering with Earth's electrical systems.
However, in recent times, the solar cyclic activities had increased and is stronger, so too are its effects. It may be more than electrical systems it
affects and may be interfering with our planet's core, which is a dynamo itself and generates a field of its own.
Started back in March, there was an experiment to see if the combined human electric and human electromagnetic field could complement our
magnetosphere as a shield against solar winds of high energy particles bombarding our planet, culminating and ended on Earth hour 27th Mar.
There is not enough scientific evidence to claim that CME will cause Earthquakes, but equally, there is not enough evidence to claim that CME DOES NOT
cause Earthquakes. Geomagnetic storms cause auroras, and such 'changes to the skies' had been observed in quake hit areas prior to devastation.
While there was no conclusive evidence that the experiment worked, the CME on the 15th Mar did not do damage to California, Japan and Sri Lanka. No
lives were lost. On the 25th Mar Manila suffered a 6.0 Earthquake, and yet no lives were lost.
The recent Earthquake in China had seen a terrible loss of lives, many of them only innocent kids. I hope that with the next announcement of a CME,
let us all - of the religious faiths, the spiritual beliefs, and atheist creed, come together and try out the experiment again. We are all human
first, before our differences set us apart, but yet one race....
