Since 1997, Jonathan has been haunted by a question: could a volcano erupt a la Dante's Peak and turn a local creek into a river of hot acid? This week, Professor Chris Jackson answers all of Jonathan's burning questions about how volcanoes are formed, what happens when they erupt, and how Pierce Brosnan's character in Dante's Peak would have fared against a real pyroclastic flow.Chris Jackson is Chair in Sustainable Geoscience at the University of Manchester and spent 16 years at Imperial College. Chris works in the general area of sedimentary basin analysis. When not studying rocks, Chris gives geoscience lectures to the public and schools, and he's appeared on several Earth Science-focused television productions and podcasts. Chris is engaged in efforts to improve equality, diversity, and inclusivity in Higher Education. He runs, too!

The images used to create this enhanced color composite of Io were acquired by NASA's Galileo spacecraft during its seventh orbit (G7) of Jupiter. Low sun angles near the terminator (day-night boundary near the left side of the image) offer lighting conditions which emphasize the topography or relief on the volcanic satellite. The topography appears very flat near the active volcanic centers such as Loki Patera (the large dark horse-shoe shaped feature near the terminator) while a variety of mountains and plateaus exist elsewhere. The big reddish-orange ring in the lower right is formed by material deposited from the eruption of Pele, Io's largest volcanic plume. North is to the top of this picture which merges images obtained with the clear, red, green, and violet filters of the solid state imaging (CCD) system on NASA's Galileo spacecraft. The resolution is 6.1 kilometers per picture element. The images were taken on April 4th, 1997 at a range of 600,000 kilometers. The Jet Propulsion Laboratory, Pasadena, CA manages the Galileo mission for NASA's Office of Space Science, Washington, DC. JPL is an operating division of California Institute of Technology (Caltech). Concurrent results from Galileo's exploration of Io appear in the October 15th, 1997 issue of Geophysical Research Letters.

The author has identified the following significant results. A large nuee ardente eruption occurred at Santiaguito volcano, within the test area on 16 September 1973. Through a system of local observers, the eruption has been described, reported to the international scientific community, extent of affected area mapped, and the new ash sampled. A more extensive report on this event will be prepared. The eruption is an excellent example of the kind of volcanic situation in which satellite thermal imagery might be useful. The Santiaguito dome is a complex mass with a whole series of historically active vents. It's location makes access difficult, yet its activity is of great concern to large agricultural populations who live downslope. Santiaguito has produced a number of large eruptions with little apparent warning. In the earlier ground survey large thermal anomalies were identified at Santiaguito. There is no way of knowing whether satellite monitoring could have detected changes in thermal anomaly patterns related to this recent event, but the position of thermal anomalies on Santiaguito and any changes in their character would be relevant information.

Impact cratering is one of the major geological processes that has affected the Martian surface throughout the planet's history. The frequency of craters within particular size ranges provides information about the formation ages and obliterative episodes of Martian geologic units. The Barlow chronology was extended by measuring small craters on the volcanoes and a number of standard terrain units. Inclusions of smaller craters in units previously analyzed by Barlow allowed for a more direct comparison between the size-frequency distribution data for volcanoes and established chronology. During this study, 11,486 craters were mapped and identified in the 1.5 to 8 km diameter range in selected regions of Mars. The results are summarized in this three page report and give a more precise estimate of the relative chronology of the Martian volcanoes. Also, the results of this study lend further support to the increasing evidence that volcanism has been a dominant geologic force throughout Martian history.

Steep sided volcanic cones along the Chilean-Argentinean border add texture to this ''study in blues.'' Of the approximately 1,800 volcanoes scattered across this region, 28 are active. This scene was acquired on February 1, 2002, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) aboard NASA's Terra satellite.

A distance of about 80 kilometers (50 miles) separates Shiveluch and Klyuchevskaya Volcanoes on Russia's Kamchatka Peninsula. Despite this distance, however, the two acted in www.spacemart.com/reports/Volcanic_Eruptions_In_Kamchatka_999.html unison on April 26, 2007, when the Advanced Spaceborne Thermal Emission and Reflection Radiometer asterweb.jpl.nasa.gov (ASTER) on NASA's terra.nasa.gov Terra satellite caught them both erupting simultaneously. ASTER ''sees'' a slightly different portion of the light spectrum than human eyes. Besides a portion of visible light, ASTER detects thermal energy, meaning it can detect volcanic activity invisible to human eyes. Inset in each image above is a thermal infrared picture of the volcano's summit. In these insets, dark red shows where temperatures are coolest, and yellowish-white shows where temperatures are hottest, heated by molten lava. Both insets show activity at the crater. In the case of Klyuchevskaya, some activity at the crater is also visible in the larger image. In the larger images, the landscapes around the volcanoes appear in varying shades of blue-gray. Dark areas on the snow surface are likely stains left over from previous eruptions of volcanic ash. Overhead, clouds dot the sky, casting their shadows on the snow, especially southeast of Shiveluch and northeast of Klyuchevskaya. To the northwest of Klyuchevskaya is a large bank of clouds, appearing as a brighter white than the snow surface. www.volcano.si.edu/world/volcano.cfm?vnum=1000-27= Shiveluch (sometimes spelled Sheveluch) and www.volcano.si.edu/world/volcano.cfm?vnum=1000-26= Klyuchevskaya (sometimes spelled Klyuchevskoy or Kliuchevskoi) are both composed of alternating layers of hardened lava, solidified ash, and rocks from earlier eruptions. Both volcanoes rank among Kamchatka's most active. Because Kamchatka is part of the Pacific www.pbs.org/edens/kamchatka/ring.html ''Ring of Fire,'' the peninsula experiences regular seismic activity as the Pacific Plate slides below other tectonic plates in the Earth's crust. Large-scale plate tectonic activity causing simultaneous volcanic eruptions in Kamchatka is not uncommon.

The borderland between Rwanda, the Democratic Republic of the Congo, and Uganda contains eight volcanoes, including Mount Nyamulagira and Mount Nyiragongo, which were both erupting on May 25, 2004. The volcanoes are both located north of Lake Kivu in Virunga National Park. The dense tropical forests of the park are home to endangered mountain gorillas. The www.awf.org/news/17081 African Wildlife Foundation does not believe that the eruptions will threaten the gorillas' habitat, but cautions that ash may contaminate drinking water sources and food crops, forcing local people to turn to the park for material. Mount Nyamulagira is Africa's most active volcano. Its neighbor 14 kilometers (9 miles) to the northwest, Nyiragongo has the world's fastest flowing lava. In 2002, 500,000 people in Goma were displaced when Nyiragongo erupted. Neither of this week's eruptions have been reported to have caused damage, though ash falls have been reported within 60 kilometers (37 miles) of the volcanoes. The modis.gsfc.nasa.gov Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's terra.nasa.gov/ Terra satellite captured this image of the eruptions on May 25, 2004. The large image shows the scene in true color. Red dots around Mount Nyiragongo indicate a thermal anomaly, and may be flowing lava or fires near the volcano. The inset shows the scene immediately around the volcanoes in false color to differentiate between cloud and the aerosol plumes. The plumes, which are a darker orange than the surrounding clouds, may be ash and steam or smoke from the fires around the volcanoes. Vegetation is dark green. The high-resolution image shows the scene in natural color at MODIS' maximum resolution of 250 meters per pixel.

Encyclopedia of Earthquakes And Volcanoes (3rd Edition)

Volcanoes are unquestionably one of the most spectacular and awe-inspiring features of the physical world. Our paradoxical fascination with them stems from their majestic beauty and powerful, if sometimes deadly, destructiveness. Notwithstanding the tremendous advances in volcanology since ancient times, some of the mystery surrounding volcanic eruptions remains today. The Encyclopedia of Volcanoes summarizes our present knowledge of volcanoes. Through its thematic organization around the melting of the earth, it provides a comprehensive source of information on the multidisciplinary influences of volcanic eruptions--both the destructive as well as the beneficial aspects. The majority of the chapters focus on the geoscience-related aspects of volcanism (radioactive heat source, melting rock, ascent of magma, surface phenomena associated with exiting magma, extraterrestrial volcanism, etc.). In addition, complementary chapters discuss the multidisciplinary aspects of volcanism; these include the history of volcanology, geothermal energy resources, interaction with the oceans and atmosphere, health aspects of volcanism, mitigation of volcanic disasters, post-eruption ecology, and the impact of eruptions on organismal biodiversity. In addition to its appeal to educators, students, and professional and amateur scientists, the Encyclopedia of Volcanoes functions as an important information resource for administrators and officials responsible for developing and implementing volcanic hazard mitigation around the world. * The first and only reference work to cover all aspects of volcanology * More than 80 separate peer-reviewed articles--all original contributions by leading authors from major institutions of science around the world, commissioned for this work * An integrated transition from the volcanic process through hazards, risk, and societal impacts, with an emphasis on how volcanoes have influenced and shaped society * Convenient single-volume format with topics arranged thematically--articles provide coverage of nine different aspects of volcanology * Each entry in the Encyclopedia begins with an outline of the article content and a concise definition of the subject of the article * 3,000 Glossary entries explain key terms * Further Reading lists appear at the end of each entry * Extensive cross-referencing system links related articles * Sixteen pages of color will convey the science and excitement of this often violent phenomena * Large 8 1/2" x 11" page size, easy-to-read double-column format
