Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
TimeMag. / DepthLocationSource
So far, we have no data about this quake from any other agency. For small quakes reported only by the relevant national agency, this is normal. For magnitudes above around 4.5, there should normally be at least 2 or 3 international agencies to report the same quake.
Note: for quakes of 2012 and earlier, our database often contains only records from USGS.
