If I remember right, your math regarding time was off by a day or so for that EQ to be related to the GRB at that time.
Quoting: Anonymous Coward 78703378 It's not MY MATH, by the way.
If you will read the article I linked to Dr. Laviolette's
report on the 2004 Sumatra Quake/Tsunami--he explained
that scientists believe there is a super-luminous gravity
wave event THAT PRECEEDED the actual detection by the
Swift Telescope for the magnatar gamma ray explosion.
Things are changing a good deal in science with regard
to "speed of light" and other delivery times of certain
cosmic energies that before 2004 were thought to be impossible.
Read the referenced links and you will understand.
And...it isn't just gamma ray bursts they are discovering
"new science" about...new information about the sun is
way way changing as well:
