Sundogs are made commonly by refraction of light from plate-shaped hexagonal ice crystals in high and cold cirrus clouds or, during very cold weather, by ice crystals called diamond dust drifting in the air at low levels. These crystals act as prisms, bending the light rays passing through them with a minimum deflection of 22°. If the crystals are randomly oriented, a complete ring around the sun is seen — a halo. But often, as the crystals sink through the air, they become vertically aligned, so sunlight is refracted horizontally — in this case, sundogs are seen.

I've never heard of clouds being a precursor for earthquakes, but the picture is beautiful. Do you have a link to an article or something as to why someone would believe that these type clouds appear before an earthquake? I've seen them before and an earthquake didn't happen.

Uh, his name is a cloud.
You should get a cloud guide.
Or go here. This guy explains the optics behind everything you can see in the sky.
Atmospheric Optics
Look for the brightly coloured circumhorizon arc (also a circumhorizontal arc but never 'fire rainbow') when the sun is very high in the sky - higher than 58°. Near to noon in mid summer is a good time in middle latitudes. The halo is beneath the sun and twice as far from it (two hand spans) as the 22º halo.
It is a very large halo and always parallel to the horizon. Often only fragments are visible where there happen to be cirrus clouds - the individual patches of cirrus are then lit with colour that can be mistaken for iridescence.
High sun infralateral arcs occupy a similar position in the sky. The infralateral arc curves upwards from the horizon slightly and this is best checked for visually because lens distortions invariably also show the circumhorizon arc as curved.
The rarity, or otherwise, of the arc depends on where you are. At medium latitudes like much of the USA it is not rare - it can be seen several times each summer. In contrast, further north in much of Europe the circumhorizon arc is a rarity and impossible to see north of Copenhagen. See the charts in 'How rare?' for the visibility at your location.

I have read many of your threads and posts, and enjoyed them, so it is with all due respect I ask you, are saying if you read it on ATS it must be true?
Mamatus is correct. There have been reports of 'lights' a phenomena visible at night, prior to earthquakes, but clouds, not so much. Clouds and earthquakes are not related. It has to do with the sun reflecting on the ice in the clouds, refraction.edit on 16-5-2013 by Iamschist because: (no reason given)
