Magnitude
There's been some edit conflict going on regarding the magnitude of the earthquake. The USGS, arguably one of the most reliable seismological centres in the world, lists this as a magnitude 6.0 event on the Moment magnitude scale (Mw). GeoNet, however, lists an upgraded magnitude of 6.3 on the Richter magnitude scale (ML). There is a subtle difference between the two, and the magnitude has been incorrectly updated to Mw 6.3. Since the USGS is by far a more notable source for earthquake data, and is consensually preferred as a main source by WP:QUAKE, I believe the magnitude given by the USGS should be used, while the magnitude from GeoNet (and other agencies) could be added as an additional note. ★ Auree talk

I feel that the GNS Science upgraded should be the main source for the magnitude. The USGS listing is only a computer generated estimate at the time of the earthquake. The upgraded GNS Science reading was calculated by seismologists from the readings of various seismographs located in the actual area. Therefore it is clear that the GNS Science reading would be the more accurate and reliable of the two. FEAR6655 —Preceding undated comment added 03:06, 14 June 2011 (UTC).


 * Sorry but GeoNet is the one which should be used as it is NZ based and is just as reliable as the USGS. Also NZ isn't a US state or territory and WP:QUAKE is not a policy or guideline. Bidgee (talk) 03:08, 14 June 2011 (UTC)
 * Fair enough, but since GeoNet uses the Richter scale, it should also be updated to ML, not Mw. ★ Auree  talk 03:15, 14 June 2011 (UTC)
 * I've just done that, as I've had to do with the other quakes (since people were misusing Mw for ML data). Bidgee (talk) 03:17, 14 June 2011 (UTC)
 * I now see 3 separate magnitudes (5.5, 5.6 and 5.7) with mixed magnitude scales for the weaker preceding earthquake throughout the article. I'm not sure what it's supposed be, but I think it was upgraded to magnitude 5.7 ML ★ Auree  talk 03:23, 14 June 2011 (UTC)
 * Never mind, it's supposed to read as 5.6 ML. ★ Auree  talk 03:23, 14 June 2011 (UTC)
