According to the data on the USGS earthquake website, this one is pretty much entirely sideways motion - the different sides of the fault are sliding past each other rather than moving towards each other. So there should be pretty minimal vertical motion of the sea floor, which is what causes tsunamis.
So there is most likely no (or very little) tsunami danger.

There have been some very big earthquakes recently. Do you think rising sea levels will bring more large earthquakes like this? The loading of the oceans is one of the most common triggers of earthquakes or so I'm led to believe.
