Volcano Hazards Program

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. The following video clips are take from "Understanding Volcanic Hazards", © 1995, International Association of Volcanology and Chemistry of Earth's Interior (IAVCEI). 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.

Volcano Livecams - Volcano Livecam If you add a link, please add it in the form: "volcano name livecam of source" and also add it to the related volcano category. Please register on the left side near the bottom for this. Thank you for your contribution! See on the bottom of the page for a map which is showing all the registered livecams. Klick on this link to get a list of all volcanoes covered in this directory. Thanks to Fred Rostorfer, Jamie Trouskie, Kevin Rogers, J. Thanks also to the different other volcano live cam sites like Stromboli Online, John Seach, Eruptions blog, Volcanism Blog and many more. And last but not least: the biggest thank you goes of course to the operators of the different volcano live cams! Stefan, National Earthquake Information Center - NEIC Earthquake Hazards Program National Earthquake Information Center - NEIC The mission of the National Earthquake Information Center (NEIC) is to determine rapidly the location and size of all destructive earthquakes worldwide and to immediately disseminate this information to concerned national and international agencies, scientists, and the general public.

San Andreas Fault Homepage: Information, photos, maps, fault location and more! New Madrid Zone sismique - cartes de l'activité séisme passé Earthquake lights Earthquake lights have been seen since ancient times. 1811-12 New Madrid quake eyewitnesses saw them possibly from as far away as Savannah GA. They were first photographed in 1968 in Japan. USGS admits their existence. Records of earthquakes that were accompanied by sky lights can be found in 373 BC in ancient Greek writings, that "immense columns of flame" foretold the earthquake that destroyed the cities of Helike and Bura. However, even in the early 20th century they were still considered a myth, until photographs of actual lights were taken in Japan in the 1960s. William Leigh Pierce, a traveler on the Mississippi, observed, "On the 30th of November, 1811 about one half hour before sun-rise, two vast electrical columns shot up from the eastern horizon, until their heads reached the zenith" -- from Feldman book >> Photograph of earthquake lights, -- more on their possible causes >>Earthquake lightning - pseudotachylites Lights' appearance Earthquake lights - causes

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.

Seismic Monitor - Recent Earthquakes The actual min mag shownon the map is about 4.2,to get a uniform distribution. Latest El Niño/La Niña Watch Data Archive of All Images These are the latest images from the OSTM/Jason-2 satellite. Jason-2 continues providing the uninterrupted time-series that originated with TOPEX/Poseidon. Jason is using radar altimetry to collect sea surface height data of all the world's oceans. What is sea-surface height? The height (or "relief") of the sea surface is caused by both gravity (which doesn't change much over 100's of years), and the active (always changing) ocean circulation. What are we looking at? These images show sea surface height anomalies with the seasonal cycle (the effects of summer, fall, winter, and spring) removed. Each image is a 10-day average of data, centered on the date indicated.
