Unrest growing among world’s supervolcanoes: Santorini in Greece, Uturuncu in Bolivia, the Yellowstone and Long Valley calderas in the U.S., Laguna del Maule in Chile, Campi Flegrei in Italy – almost all of the world’s active supervolcanic systems are now exhibiting some signs of inflation- a potential early indication that an eruption could be building in these volcanic systems for the near future.
November 2, 2013 – GEOLOGY – One of these days, a field of volcanoes you have never heard of will wake up, and if it fulfills its geologic potential, the consequences will be heard around the world. Curiously, Laguna del Maule, situated along the spine of the Andes, doesn’t even look like a volcano. No towering peak, no plume of smoke or steam, no stench of sulfur. But 36 times in the past 20,000 years, volcanic vents surrounding the lake basin have created monster fields of lava
Just 50 kilometers north of Laguna del Maule, a similar volcanic field, called Calabozos, has had three super-eruptions in the past million years, spewing about 1,000 cubic kilometers of ash in total. Those eruptions rank among the largest in a million years. -WF
The lava pool beneath Yellowstone National Park is more than twice as big as scientists previously believed, that’s according to new research from the Geological Society of America. Scientists from the University of Utah say the lake of molten lava is nearly 50 miles long and 12 miles wide.
...Could global warming be comming from the inside and not the pollution?
Mount Sinabung in Indonesia has erupted for the third time in as many months, spewing ash over 4 miles into the air and covering nearby villages in gray powder. The volcanic activity began on Sunday and more than 1200 people have been evacuated so far. The volcano surprised scientists in 2010 when it rumbled back to life after being dormant for centuries. Sinabung is one of 120 active volcanoes in the country which is located on the Pacific “Ring of Fire.
A remote Russian volcano may be readying for a new eruption, according to NASA's Earth Observatory. On Nov. 5, NASA's Earth-Observing 1 satellite spotted ash above the 9,702-foot-tall (2,958 meters) Zhupanovksy volcano, which recently woke from a decades-long slumber. The snowy peaks also shows signs of phreatic explosions — the stupendous blasts that result from hot lava meeting snow, ice or water, the Earth Observatory reported.
