when the depth is zero it means the quake has not been reviewed by a seismologist yet
These parameters provide information on the reliability of the earthquake location. Zero values usually indicate that the contributing seismic network did not supply the information.
seems closest to the matter, bizarrely confuse me lol ) but thanks, though.
Erzz The depth error, in km, defined as the largest projection of the three principal errors on a vertical line. See Erho
Sometimes it is simply a very shallow event with poor depth resolution, but more often it is not actually an earthquake, but a quarry blast. These explosions are recorded by the seismic network and located by the software. When they are reviewed by a seismic analyst, they are labeled as a quarry blast in the earthquake catalog.
