Personally think this events are connected and gamma rays or cosmic rays, EM radiation from space can cause strongest earthquakes on Earth ..
Scientists have detected a flash of light from across the Galaxy so powerful that it bounced off the Moon and lit up the Earth's upper atmosphere. The flash was brighter than anything ever detected from beyond our Solar System and lasted over a tenth of a second. NASA and European satellites and many radio telescopes detected the flash and its aftermath on December 27, 2004. Two science teams report about this event at a special press event today at NASA headquarters. A multitude of papers are planned for publication.
"This might be a once-in-a-lifetime event for astronomers, as well as for the neutron star," said Dr. David Palmer of Los Alamos National Laboratory, lead author on a paper describing the Swift observation. "We know of only two other giant flares in the past 35 years, and this December event was one hundred times more powerful."

SGR 1806-20
On December 27, 2004, the radiation from an explosion on the surface of SGR 1806-20 reached Earth.[2] In terms of gamma rays, the burst had an absolute magnitude around −291. It was the brightest event known to have been sighted on this planet from an origin outside our solar system. The gamma rays struck the ionosphere and created more ionization, which briefly expanded the ionosphere. The magnetar released more energy in one-tenth of a second (1.3×1039 J) than our sun has released in 100,000 years (4×1026 W × 3.2×1012 s = 1.3×1039 J). Such a burst is thought to be the largest explosion observed by humans in the galaxy since the SN 1604 supernova observed by Johannes Kepler in 1604.
A similar blast within 3 parsecs (10 light years) of Earth would destroy the ozone layer and would be similar in effect to a 12 kt of TNT (50 TJ) nuclear blast at 7.5 km. The nearest known magnetar to earth is 1E 1048.1-5937, located 9,000 light-years away in the constellation
