Russia's Sarychev Peak volcano started erupting on June 12, 2009. The following explains why our recent sunrises and sunsets (we certainly haven't seen many of these recently) have been quite spectacular. |
| PURPLE SUNSETS: High up in the stratosphere,
sulfur dioxide emissions from Russian's Sarychev Peak
volcano have circumnavigated the northern hemisphere. As a
result, purple sunsets are appearing at all longitudes. How do volcanoes turn the sky purple? Fine, sulfurous aerosols in the stratosphere scatter blue light. Blue mixes with ordinary sunset red to produce the lavender hue. It has been a full month since Sarychev Peak erupted and the purple is still being sighted on a regular basis from Russia, Canada, Iceland, northern-tier US states and many countries in Europe.
