I expect after review by a seismologist they will revise the data/description.
I don't think it's possible to infer from seismic that a shock took place way above ground. I would be suspecting a data error.
Watch this space if it really bothers you. I used to get notifications that a magnitude had been changed or a tentatively-ID'd EQ had been deleted after review by a seismologist, on the stronger quakes that I subscribed to.
