Reviewing data is very important, especially when you are following trends or compiling graphs.
I did it for a while on my NZ earthquakes blog a few years back, but it was too much work, especially when the Christchurch quakes hit, actually it
might have been the 2009 Dusky Sound 7.6 that made me throw the files away.
But I've got back into it, partly with the help of QVS DataPro to get the Preliminary data, its faster.
Here is a prime example of what difference a review can make.
One event. Source: Geonet
Date/Time UTC: 01/03/2014 02:33:59
Latitude, Longitude: -36.51749, 178.80264
Energy Released (TTNT): 3.6594
Location: Auckland-Coromandel-Whakatane Seamount
Status: reviewed, Updated on: 05/03/2014 04:39:10
When: 01/03/2014 02:33:47 UTC (12 second difference)
Lat/Long: -35.6084 179.764 (different location)
Depth: 33 km (shallower)
Mag: 4.0942 ML (bigger)
No. of Phases used: 53
Location: Whangarei-Rumble3-Healy (now in a totally different GL Region)
now the most significant difference
Energy Released: 20.8789 tonnes of TNT
17.2 Tonnes of TNT makes a BIG difference in the energy released when building a monthly/yearly ER graph.
the difference of TTNTER, thats about a M4.04, on top of the M3.59 !!!!!
*I believe I don't need ex tags, as I created the data myself, source is mentioned
