USGS California Volcano Observatory Opens
February 10, 2012 | USGS
“More than 500 volcanic vents have been identified in the State of California. At least 76 of these vents have erupted, some repeatedly, during the last 10,000 years. … Sooner or later, volcanoes in California will erupt again, and they could have serious impacts on the health and safety of the State’s citizens as well as on its economy.” Quoted from the USGS press release. |

Tree Rings for Measuring Climate Response to Volcanic Eruptions
February 8, 2012 | National Science Foundation
“Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change because large enough temperature drops lead to greatly shortened or even absent growing seasons, according to climate researchers, who compared tree-ring temperature reconstructions with model simulations of past temperature changes.” |

New Eruption Dates for Ubehebe Crater
February 3, 2012 | Wired Science
Recent research on Ubehebe Crater of California’s Death Valley reveals that it last erupted about 800 years ago instead of the previously-believed date of several thousand years ago. Erik Klementti comments on this new date. |

Continued Eruption at Puyehue-Cordón Caulle
February 3, 2012 | NASA Earth Observatory
“Eight months of ceaseless activity have covered the landscape around Chile’s Puyehue Cordón Caulle Volcanic Complex in ash. The light-colored ash appears most clearly on the rocky, alpine slopes surrounding the active vent and Puyehue’s 2,236 meter (7,336 foot)-tall caldera.” Quote from the Earth Observatory image release.

Satellite Image of Kilauea Caldera
February 1, 2012 | NASA Earth Observatory
“Shown here are two natural-color views: a close-up of the Kilauea Caldera and the Hawaiian Volcano Observatory, and a wide-area view showing Mauna Ulu and Pu’u ’O’o. Within the Kilauea Caldera lies Halema’uma’u Crater. A small plume of water vapor emerges from this crater and blows toward the southwest.” Quoted from the NASA image release.

Volcanic Hazards in California
January 31, 2012 | USGS
“More than 500 volcanic vents have been identified in the State of California. At least 76 of these vents have erupted, some repeatedly, during the last 10,000 yr. Past volcanic activity has ranged in scale and type from small rhyolitic and basaltic eruptions through large catastrophic rhyolitic eruptions.” Quoted from the USGS report.

New Island in the Red Sea
January 10, 2012 | NASA Earth Observatory
A January 7th satellite image of the Red Sea shows the new volcanic island about 40 miles off the cost of Yemen. The pushpin on the Google Map at right shows the location of the new island. For an image showing steam and ash escaping from the vent visit the Earth Observatory website. If you look closely at the zoomed in map you will see that the island is located in the center of the Red Sea Rift. |

Deep Well Injection and Earthquakes in a Geothermal Field
December 26, 2011 | Oregon Public Broadcasting
An article on the Oregon Public Broadcasting website describes the proposed use of fluid injection as part of an enhanced geothermal system that will utilize wells drilled on the flank of Newberry Crater. The U.S. Department of Energy is putting $22 million into the project. USGS has a recently installed seismic array that will monitor earthquakes produced by the injection.
