Volcanic Rays

Add to Cart Add to Lightbox Download

Sunsets with a purple hue like this one have been common lately. They are caused by extra ash in the stratosphere from the eruptions of Raikoke and Ulawan Volcanoes this past summer. The purple color usually peaks 15 minutes after sunset or before sunrise. When there are clouds at the horizon their shadows can cast long crepuscular rays across the sky.
