Space Imaging has kindly provided Volcano World with some excellent IKONOS satellite images of Earth's volcano es. We are grateful for their contribution and support. (volcano.und.nodak.edu/)
The VW staff would like to thank everyone for their continued support and apologize for the brief interruption in updates while we were transitioning both equipment and staff. We will continue to work with our volcano web partners from around the world to keep VW fresh and add web features as they become available. There are several new features coming to VW in the coming months including a volcano blog, GIS layers, local area volcano maps, and more! The RSS site feed and weekly updates will all be back online starting December 15th! (volcano.und.nodak.edu/)
This radar image of Titan shows Ganesa Macula, interpreted as a cryovolcano (ice volcano ), and its surroundings. Cryovolcanism is thought to have been an important process on Titan and may still be happening today. This mosaic was made from images obtained by the Cassini radar mapper on two flybys. The lower part of the image was from the flyby on Oct. 26, 2004, while the upper part was from the Jan. 13, 2007, flyby (volcano.und.nodak.edu/)
JAKARTA (AFP) Farmers residing on the slopes of a smouldering Indonesian volcano are thanking the mountain for getting rid of a pest that had devastated the area's coconut palms, a report here said Tuesday.Gamkonora volcano on Halmahera island in Indonesia 's North Maluku province erupted in July, shooting rocks, ash and smoke into the air for days and prompting thousands to flee their homes."Almost all our coconut trees were previously ruined by the sexava pest. Now we are completely free of this pest, following Gamkonora blanketing the area with ash in July," the state Antara news agency quoted a local farmer, Yakup, as saying (volcano.und.nodak.edu/)
Recognizing that there are potentially dangerous volcano es within the United States and its Territories that have inadequate or no ground-based monitoring, the USGS Volcano Hazards Program, with CUSVO, is preparing a plan for a National Volcano Early Warning System (NVEWS). (volcanoes.usgs.gov/)
Jim Kauahikaua, the Scientist-in-Charge of the Hawaiian Volcano Observatory, hasjust released a new hazard assessment, Lava flow hazard assessment, as of August 2007, for Kilauea East Rift Zone eruptions, Hawai'i Island .The most recent episode in the ongoing Pu'u 'O'o Kupaianaha eruption of KÄ«lauea Volcano is currently producing lava flownorth of the east rift zone. Although they pose no immediate threat to communities, changes in flow behavior could conceivably cause future flows to advance downrift and impact communities thus far unaffected. This report reviews lava flow hazards in the Puna District and discusses the potential hazards posed by the recent change in activity. Members of the public are advised to increase their general awareness of these hazards and stay up-to-date on current conditions.

A National Volcano Early Warning System (NVEWS) is being formulated by the Consortium of U.S. Volcano Observatories (CUSVO) to establish a proactive, fully integrated, national-scale monitoring effort that ensures the most threatening volcano es in the United States are properly monitored in advance of the onset of unrest and at levels commensurate with the threats posed. Volcanic threat is the combination of hazards (the destructive natural phenomena produced by a volcano ) and exposure (people and property at risk from the hazards) (volcanoes.usgs.gov/)
Try your hand at predicting an eruption of Mount St. Helens volcano using data collected by scientists of the USGS Cascades Volcano Observatory. This presentation uses data from several eruptive episodes of Mount St. Helens in the 1980's to show the way in which a series of eruptions were accurately predicted by USGS scientists as far as 3 weeks in advance.

Two Hundred years ago on October 16, 1805, Lewis and Clark and the men of the "Corps of Discovery " reached the Columbia River. On October 18, 1805, the men began their journey down the Columbia River where they reached the Pacific Ocean on November 15, 1805. On the journey the men saw five different Cascade Range volcano es. They even named Mount Jefferson after their benefactor, Thomas Jefferson . The Cascades Volcano Observatory's "The Volcano es of Lewis and Clark" begins on the Clearwater River in early October, and uses the 1814 Biddle publication of the journey to follow Lewis and Clark down the Clearwater, Snake, and Columbia Rivers. This web presentation includes old illustrations, maps, and information about the landscape and the volcano es which Lewis and Clark saw. (vulcan.wr.usgs.gov/)
The Cascade magmatic arc is a belt of Quaternary volcano es that extends 1,250 km from Lassen Peak in northern California to Meager Mountain in Canada, above the subduction zone where the Juan de Fuca Plate plunges beneath the North American Plate. Newly published Professional Paper 1744, Quaternary Magmatism in the CascadesâGeologic Perspectives by Wes Hildreth, presents a synthesis of the entire volcanic arc, addressing all 2,300 known Quaternary volcano es. Wes Hildrethâs insightful understanding of volcanic processes and his uncompromising scientific integrity make him uniquely qualified to present this synthesis. During more than three decades of volcano logical studies, he has carried out comprehensive investigations of Mount Adams, Mount Baker, the Three Sisters , and the Simcoe Mountains Volcanic Field. He also brings a broad experience in other volcanic arcs, having conducted integrated field and laboratory investigations at several major volcanic centers in the Andes and the Aleutian arc (volcanoes.usgs.gov/)
According to a new USGS report on NVEWS , since 1980, 45 eruptions and 15 cases of notable volcanic unrest have occurred at 33 U.S. volcano es. About half of the most threatening U.S. volcano es are monitored at a basic level and a few are well monitored with a suite of modern instruments. However, the report cautions, monitoring capabilities at many hazardous volcano es are sparse or antiquated, and some hazardous volcano es have no ground-based monitoring whatsoever.
