a little gif animation to show how the JMA/NIED review changes things
animation shows the preliminary versus reviewed, the preliminary one is the one with the lighter orange bar at 19:25.
the graphs show the bigger quakes in a lighter hue of orange, so bigger the quake the lighter the hue . And a couple of others were added or upgraded
or downgraded in sizeThat 5.6 at 19:25 downgraded to 5.2 so being smaller the bar is darker, and the new one added on the graph in front of the 5.2
was a 3.7 Southwestern Ryukyu Isl
I have noticed that generally the review reduces the magnitude reading compared to the automatic reading, note also the 3.6 and 15:07 and 3.5 at 15:15
also went down, to 2.9 and 3.4 repectively.
for clarity here are the 2 images together, preliminary on the top, reviewed below
the first half of the preliminary graph had reviewed data to 18:00hrs, that is why no change there.
therefore caution should be taken when looking at preliminary (automatic) data
