Along with what EvilSWAT mentioned; the quake appears to have been a "strike-slip" quake, essentially like rubbing your hands together horizontally, not vertically. Given this, the likelihood of another tsunami was very minimal, as they are caused by vertical impacts on the plates which cause the ocean to rise and fall.
That said, I'm sure that the tremors would have been very worrisome for anyone nearby, so be careful guys
