GOES Satellites See Ash Still Spewing from Chilean Volcano

30.06.2011
The Puyehue-Cordón volcano in Chile continues to spew ash that is still disrupting travel as far as Australia and New Zealand this week. A new animation of satellite imagery just released from the NASA/NOAA GOES Project shows the ash spewing from the volcano.

Satellite data from the Geostationary Operational Environmental Satellites called GOES-13 and GOES-11, both managed by NOAA, have been providing images of the volcanic plume since the eruption began on June 4, 2011. Those images were created at NASA's GOES Project located at NASA's Goddard Space Flight Center, Greenbelt, Md. The images were compiled into an animation and sped up to show several days worth of eruptions in less than a minute.

The animation begins on June 24 at 0039 UTC (June 23 8:39 p.m. EDT) and runs 22 seconds. In the animation, the ash plume originally appears very thin as it blows northward. As the time series continues, the plume thickens and blows to the northwest into the Pacific Ocean. The animation ends on June 26 at 23:45 UTC (7:35 p.m. EDT).

Dennis Chesters of the NASA GOES Project noted of the animation, "The Chilean caldera still emits a steady stream of ash, three weeks after the initial eruption. Fortunately, the volume is much less, and the cold winter wind from the south carries it up the coast out over the Pacific, instead of over the Andes into Argentina."

According to CNN on June 28, the volcanic ash cloud was still affecting air travel in New Zealand, Australia. The eruptions of the Puyehue volcano, located in Puyehue National Park in the Andes of Ranco Province of Chile have also caused flight delays and cancellations in Argentina, Brazil, Chile and Uruguay.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
