Terrestrial Volcanoes Terrestrial Volcanoes By turns hot embers from her entrails fly, And flakes of mountain flame that arch the sky.-Virgil's Aeneid Volcanoes destroy and volcanoes create. Ironically, these volcanic soils and inviting terranes have attracted, and continue to attract, people to live on the flanks of volcanoes. On August 24, A.D. 79, Vesuvius Volcano suddenly exploded and destroyed the Roman cities of Pompeii and Herculaneum. In the United States on March 27, 1980, Mount St. The word volcano comes from the little island of Vulcano in the Mediterranean Sea off Sicily.

Views of Terrestrial Volcanoes Llullaillaco Volcano The summit of South America's Llullaillaco Volcano has an elevation of 22,110 feet above sea level, making it the highest historically active volcano in the world.

San Andreas Fault Homepage: Information, photos, maps, fault location and more! National Geographic: Eye in the Sky--Volcanoes Volcanoes are awesome manifestations of the fiery power contained deep within the Earth. These formations are essentially vents on the Earth's surface where molten rock, debris, and gases from the planet's interior are emitted. When thick magma and large amounts of gas build up under the surface, eruptions can be explosive, expelling lava, rocks and ash into the air. Less gas and more viscous magma usually mean a less dramatic eruption, often causing streams of lava to ooze from the vent. The mountain-like mounds that we associate with volcanoes are what remain after the material spewed during eruptions has collected and hardened around the vent. A large eruption can be extremely dangerous for people living near a volcano. Volcanoes tend to exist along the edges between tectonic plates, massive rock slabs that make up Earth's surface. About 1,900 volcanoes on Earth are considered active, meaning they show some level of activity and are likely to explode again.
Thuban is a former Pole Star | Brightest Stars Thuban is not a particularly bright star, but it holds a special place in the hearts of stargazers. That’s because Thuban was the Pole Star some 5,000 years ago, when the Egyptians were building the pyramids. Among the many mysteries surrounding Egypt’s pyramids are the so-called “air shafts” in the Great Pyramid of Giza. These narrow passageways were once thought to serve for ventilation as the pyramids were being built. In the 1960s, though, the air shafts were recognized as being aligned with stars or areas of sky as the sky appeared for the pyramids’ builders 5,000 years ago. The Great Pyramid of Giza, an enduring monument of ancient Egypt. This diagram shows the so-called air shafts in the Great Pyramid. One of the “air shafts” follows a crooked course through the Great Pyramid, so you couldn’t have sighted stars through it. The 26,000-year precession cycle causes the north celestial pole to move counter-clockwise relative to the backdrop stars. How to see Thuban.

Mount St Helens Feature Pictured is the ash-and-gas plume produced during the plinian phase of the climactic eruption of Mount St. Helens that began shortly after 8:32 a.m. Pacific Daylight Time on May 18, 1980. Photograph taken by Robert M. Twenty years ago in late March, southwestern Washington’s Mount St. This eruption caused the worst volcanic disaster in the recorded history of the United States, resulting in 57 deaths, scores of injuries and economic loss exceeding $1 billion. Modern volcanologic studies began early in the 20th century, in large part reflecting the scientific and societal need to better understand “how volcanoes work” in the wake of three 1902 eruptions that claimed more than 36,000 lives: Mont Pelée, Martinique; Soufrière, St. The reawakening of Mount St. The 1980 and subsequent eruptions of Mount St. Analysis of a precisely timed series of photographs, coupled with eyewitness accounts, indicated that the north flank of Mount St. Anticipating the eruption Ruiz and Pinatubo
