Incandescent lava fountains play above an eruptive fissure at Krafla volcano in NE Iceland on September 6, 1984. After a quiet interval of 33 months, an eruption began on September 4 along a fissure extending from Leirhnjúkur 8.5 km to the north. Initially, the fissure was active along its entire length, but later lava production was highest at the northern end of the fissure. Photo by Michael Ryan, 1984 (U.S. Geological Survey).

Volcano vs. Supervolcano 1. Volcano: Common volcanos such as Láscar and Uturuncu are formed when water is released from oceanic plates in subduction zones. Supervolcanos are also found near subduction zones, or above mid-plate hotspots.

Volcanic explosivity index
Explosions Volcanic, Volcanic Explosions, Volcanic Eruption, Widely Known Explosions
The Volcanic Explosivity Index is used to compare the size of explosive volcanic eruptions. Image; The spheres in the illustration represent the volume of erupted tephra for some of the most widely-known explosive volcanic eruptions. Although most people believe that Vesuvius (79 AD - the Pompeii eruption), Mount St. Helens (1980) and Mount Pinatubo (1991) were enormous, they are very small compared to ancient eruptions such as Wah Wah Springs, Toba, Yellowstone or Long Valley Caldera.

Stunning Infographics and Data Visualization
This Geologic Time Spiral Infographic shows the geologic timeline of the Earth, which is 4.6 billion years old. It attempts to visualize a very difficult concept, the idea of how long 4.6 billion years really is. Because of human's large number bias and inability to comprehend such large numbers, we cannot really grasp how long 4.6 billion years really is. If the time of earth was put onto a 12-hour clock, human existence would equate to less than one-tenth of a second.

Geek gift: Gallium- melting point is 85 degrees, melts in your hand. purchase link http://www.mcssl.com/store/gallium-source/gallium-metal
11 cheap gifts guaranteed to impress science geeks: Gallium is a silvery metal with atomic number 31. It's used in semiconductors and LEDs, but the cool thing about it is its melting point, which is only about 85 degrees Fahrenheit. If you hold a solid gallium crystal in your hand, your body heat will cause it to slowly melt into a silvery metallic puddle. Pour it into a dish, and it freezes back into a solid. Price: $80
Gallium: A metal with a melting point of a little over 27 degrees centigrade. Meaning it melts from solid state to liquid state in your hand. I've had my hands on this stuff a few times and its counter-intuitive physical state is lots of fun!
An interesting gift idea for a science fanatic. 20 grams of 99.99% pure Gallium Metal. At this purity Gallium metal will melt just from the warmth of a human hand.

In this beautiful close up by gemstone hobbyist Jeff Schultz, we see a stunning Mexican fire opal. When illuminated just right, it looks like a sunset above the clouds. Fire opals are transparent to translucent with warm body colors of yellow, orange, orange-yellow or red. The most popular source of fire opals is the state of Querétaro in Mexico.

Veszelyite. One of the minerals called phosphates. All phosphates have the phosphate group, PO4, in their chemical composition. Many phosphates form from the chemical alteration of other minerals in the presence of oxygen. Group: Phosphates. Image Number: 97-35129. Catalog Number: 148368. M. Stuart

Smithsonite. The mineral was named after James Smithson, the British chemist and mineralogist who first recognized it as a distinct mineral, different from calamine(hemimorphite). It is mined for zinc. James Smithson (1754-1829) was the founder of the Smithsonian Institution. Group: Carbonates, Image Number: MSA 62

Liddicoatite. Slice from a single crystal of liddicoatite. The colour-zoning reveal the crystal's history, just as the rings in a tree records its past. Crystals may start and stop growing many times. In most cases, there is no way of knowing how long each phase lasted. This particular crystal changed color as it grew. The pink portion of the liddicoatite formed when the solution feeding it was manganese rich. The green part grew when the solution became iron rich.
