In the December 2001 issue of National Geographic, Dr. Rick Aster, Earth and Environmental Science, is quoted in the lead article on Antarctica. National Geographic is one of the most widely disseminated periodicals in the world, with an English language circulation of approximately 8.6 million.
The copyrighted article begins, "Nearing the crater rim, Rick Aster paused for a warning: 'Don't try to run if it erupts. Just stand still, look up, and be ready to step aside if anything comes your way. This thing can throw lava bombs the size of a sofa.'
Aster, a geophysicist from the New Mexico Institute of Mining and Technology, issued this warning at the summit of Moutn Erebus, a massive volcano thrusting nearly two and a half miles above the Ross Sea off the coast of East Antarctica."
