Red Red Sun

Combine a sunset with a layer of vog (volcanic haze), and we get red sunsets. When the winds blow from the south-southeast (Kona winds), vog gets blown up to O‘ahu from Hawai‘i (the Big Island) where there is an active, erupting volcano, Kīlauea, in the eastern part of the Big Island. Plus there is another active volcano, Mauna Loa, in the center of the island. The vog actually looks like smog seen in Los Angeles, Tokyo, or Beijing. Thankfully, the vog only happens when the Kona's blow, and the tradewinds blow them out to sea.
