Hint : our solar system is approaching the dense , star-rich area called the Orion Arm , threfore a more dynamic and stronger Gravitational space ... good luck !
Next thing the scientists will tell us is that the tormented magma will be squized upwards becaming Lava and warming the air and water ... oh NO , A Natural Global Warming ! ... and stronger earthquakes and volcanism .
Oh yes , the Fukushima too ...

Researcher: Gravity of moon, sun likely unleashed Tohoku quake
.... The gravity of the moon and the sun likely triggered the Great East Japan Earthquake last year, according to a Japanese researcher.
Sachiko Tanaka, of the National Research Institute for Earth Science and Disaster Prevention, studied the correlation between gravitational pull and earthquakes off the coast of the Tohoku region over a 36-year period.
She said she found that the quakes before the disastrous temblor on March 11, 2011, tended to strike when the gravitational effects were strong.
The Earth goes through two cycles of expansion and contraction by about 20 centimeters a day due to the gravitational pull of the moon and the sun. Although the force from the gravity is only around one-thousandth of the typical stress that has built up in a tectonic plate, it could be enough to set off an earthquake, she said.
“As stress that can cause a huge earthquake has built up in a plate, a small force could be a trigger,” Tanaka said.
She said studies of the gravitational effects and the frequency of earthquakes could provide signs that a huge quake is approaching.
Specifically, Tanaka analyzed about 500 temblors with a magnitude of 5.0 or greater between 1976 and 2011 in a 500-kilometer-by-200-km area of the fault that caused the magnitude-9.0 earthquake on March 11 last year.
She detected no correlation between the gravity and earthquake occurrences in the 25 years from 1976 ...
