The Feat Color Scans Whitebeard KOed a Vice Admiral with a Quake powerful enough to have its aftershocks be perceptible to a human well off into the distance beyond Marineford.

As you might be able to tell, the farmer's able to tell the Earthquakes are occurring during the day, outdoors, much as described as being a magnitude 4-4.9 from where they're located.

Distance Between Islands = 182 pixels
Distance Between Islands/Alabasta = 7.913
Distance Between Islands =
27,431,601.45 meters Why not just scale directly from Alabasta? If you noticed above? There are no islands large enough near Alabasta to be visible from our bird's eye view. To account for this, we need to scale from the distance between islands on the Grand Line as shown on the globe. Where I scaled is likely not even Alabasta, but the odds are pretty good that Alabasta's not even an island large enough to be seen on the scale of the globe anyway.
Distance Between Islands = 6 pixels

Grand Line =
44,809,520.969 meters The Island was apparently remote enough where it had no clue that Whitebeard was even in a naval conflict with Marineford,
despite every sea in the setting discussing the issue like its the fucking apocalypse, so it seems like a generous low end to suggest just somewhere vaguely off panel is functionally how far away the remote island is from Marineford proper. Mind you, the direction isn't defined, so I just used the 3 chosen for the purpose of serving as our approximations.

Where A(mm) is the height of the largest seismic wave (s wave) in millimeters (mm) and delta(t) is the S-P time difference.
Look to GM's version for what I'll use as the s wave height (5000 mm)
Whitebeard's Quakes (Calculations & Assumptions) Chahige wanted me to take a look at Whitebeard's quakes in more detail, since the damage that they appear to cause probably doesn't even come close to reflect the energy involved looking at...

The S-P time difference is derived by dividing the Distance to Remote Island in miles by 5.7.
