"Fun, informative and excellent format! Thanks for a great and useful app. Suggested entry for a future update: ``Vog``, the hazardous but often invisible ``Volcanic Smog`` that occurs in places with active volcanoes - something the travel brochures fail to warn potential visitors about in tropical paradises within the``Ring of Fire``. The Natives all know, but keep it on the quiet so as not to harm tourism."

"Scientifically accurate, with real world occurrences provided, but written so someone can understand the phenomena if they are interested enough to read to learn about it. I think its fun."
