Alexandria, VA – A complex interaction between lava and water, rather than a fight between mythical troll-beasts of lore, is responsible for the occurrence of rare terrestrial basalt pillars. EARTH Magazine uncovers the truth behind the pillars in the February issue.

One of the greatest controversies in science is what's underneath the Yellowstone supervolcano. The controversy surrounds a unique relationship between a mantle plume (like the one that powers Hawaiian volcanoes) and the subduction zone off the Washington-Oregon coast. Cutting-edge research using a common kitchen ingredient is explored in the latest issue of EARTH Magazine.

It's not every day that lava flows through a college campus parking lot. But, since January 2010, Syracuse University has been bringing the lava to Central New York. Using commercially available basalt gravel and a coke-fired furnace, the geologists involved with the Syracuse University Lava Project are able to produce a wide range of flow morphologies and other features at a scale comparable to natural flows.

Volcanism is often implicated in periods of abrupt cooling. After the 1991 eruption of Mount Pinatubo in the Philippines, for instance, global temperatures dropped by half a degree Celsius due to airborne particulate matter blocking solar radiation. However, these effects don't normally last more than a few years. Yet, a recent study blames volcanism for a 500-year cold period referred to as the Little Ice Age.

Beautiful views and exotic thrills draw millions of tourists to volcanic sites each year. Previously frequented by smaller numbers of experienced hikers and trained tour guides, today's volcanic sites are plagued by throngs of novice hikers, who are often ill-prepared and uneducated about the risks of volcano geotourism. These groups of vacation-goers often display a lackadaisical attitude about safety that can put their lives at risk.

Supervolcanoes are one of nature's most destructive forces. In a matter of hours, an eruption from a supervolcano can force thousands of cubic meters of molten rock above ground, and scar landscapes with massive calderas and craters. These catastrophic eruptions have a global impact, and yet scientists still do not fully understand them. Today, a team of scientists studying Bolivia's Uturuncu volcano are trying to shed some light on how supervolcanoes can become so powerful.
