5 active volcanoes to keep an eye on Italy's Mount Etna and Mexico's Popocatépetl volcano have been huffing and puffing their way into the news recently, spewing plumes of ash and dribbling lava in the latest flare-ups of eruptive activity that have been going on for years in the case of both volcanoes. While larger eruptions, such as Indonesia's Pinatubo in 1991 and the 1980 blast of Mount St. Helens in Washington, are more famous for the disruptions they caused, some near-constant eruptions have their own associated hazard, posing threats to nearby communities and potential disruptions to air traffic from ash plumes. The Fleet Numerical Meteorology and Oceanography Center (FNMOC) The Fleet Numerical Meteorology and Oceanography Center (FNMOC) provides the highest quality, most relevant and timely worldwide meteorology and oceanography support to U.S. and coalition forces from its Operations Center in Monterey, California. Meteorology Products This area provides Global & Regional Weather Prediction Charts (WXMAP) and Global Ensemble Weather Prediction Charts (EFS).
Posters This poster combines a visualization of ground motion resulting from the February 21, 2008 M 6.0 earthquake that occurred near Wells, NV, with the image of a faucet to illustrate a classic Earth science functional analogy: "Seismic waves radiate outward from an earthquake's epicenter like ripples on water". For students this discrepant image attracts attention and links the unfamiliar concept of the spreading out of seismic waves (the target) to a similar but more familiar scenario of ripples on water radiating outwards in all directions after a droplet or pebble falls onto it (the analog). Additionally the material is made approachable by using a clean artistic design, ideas students are likely to have experienced, and a prominent URL where students to learn more. When presented at the beginning of seismic waves instruction, this poster and it's question (Earthquakes... like ripples on water?) becomes the catalyst for student-generated questions, inquiry, and learning.
Tens Of People Arrested In East & West Azarbaijan Protesting The Drying Up Of Lake Uromieh « persianbanoo May 22, 2012 Under increased heavy security atmosphere in East and West Azarbaijan, tens of people were arrested by police and Intelligence Ministry in the last two days. Yesterday in Tabriz, during scattered demonstrations protesting drying up of Lake Uromieh, Esrafil Omidi a post graduate student at Shahid Beheshti university in Uromieh and activists Mostafa Avazpour and Ghader Norouzi were arrested.
The Earth's Crust, Mantle, and Core How Do We Know? If scientists have never studied any materials from a depth below 7 miles, then how is it that we know what is in the center of the Earth? How can we know what the core of the Earth is made of, if we have never seen it? The answer is actually quite simple. Mt. Etna erupts with fountains of lava - Science Fair: Science and Space News Updated 2011-07-20 10:14 AM Mt. Etna lava fountain, blindingly bright, even in a wide-angle shot of the summit area. Uly 19, 2011. By Photo courtesy: Tom Pfeiffer / www.volcanodiscovery.com Iceland's gotten all the press of late, but there are other volcanoes in the world. visualizing.org Since 2005, Europe has been running the world's largest greenhouse gas market, capping emissions of its major factories and power stations, and allowing those companies to buy and sell pollution permits amongst themselves, as well as on the international "offsets" market, where funds go towards developing world projects that help curb emissions. The permits were originally handed out for free instead of by auction – a practice that, according to the Times, has likely earned some of the heaviest CO2 emitters billions of extra euros since 2005. There were also far too many credits initially issued at a time when dirty fuel was ridiculously cheap, leaving polluters with plenty of breathing room and inspiring some, like energy expert David Victor, to call the European Trading System little more than a "Potemkin market." The British non-profit organization Sandbag has created this map-based visualization in an attempt to illuminate the unwieldy world of carbon trading.
Rischio Sismico - Aplicaciones de Android - Use your smartphone or pad as a vibrometer to automatically detect earthquakes and vibrations. Set an alarm in case the smartphone detects vibrations. - Use the app as an alerter and fire a sound alarm in case a quake is detected. Report an earthquake that you felt and see the real time map with the reports of the other users and their messages related to the quake. Use the chat to share information about the quakes.
We must set planetary boundaries wisely As pressure on resources increases, pollution accumulates and humanity's impact on Earth escalates, global-scale governance of the environment is increasingly necessary. In June, the United Nations' Rio+20 Earth Summit in Rio de Janeiro, Brazil, will grapple with these difficult political issues. Up for discussion is a relatively new scientific concept: planetary boundaries. Formulated in 2009 by Johan Rockström, director of the Stockholm Environment Institute, and his colleagues, the concept is based on the idea that humanity flourished under the conditions on Earth in the 10,000 years leading up to the industrial revolution — the Holocene epoch. So, to maintain human progress, we should keep the planet under similar biophysical conditions. The researchers set out nine key environmental measures and thresholds that should not be breached for fear of pushing Earth out of the Holocene-like 'safe operating space for humanity'.
The Earth and the Moon What's covered here:What are the physical characteristics of the Earth's interior, surface and atmosphere? What are the physical characteristics of the Moon? Where did the Moon come from? Even though you might not think of it as such, the Earth is a planet. Here we're just going to treat it like one.
