Suomi NPP Satellite Data Used for Mitigating Aviation Related Volcanic Hazards

Rob Gutro, NASA Goddard Space Flight Center A joint NOAA/NASA satellite is one of several satellites providing valuable information to aviators about volcanic hazards. An aviation "orange" alert was posted on August 18, 2014, for Bárðarbunga,...

Improving Volcanic Ash Forecasts For Aviation Safety
2013-10-26 05:29:46

April Flowers for redOrbit.com - Your Universe Online Frequent travelers can agree that flight delays are all too familiar these days. NASA is looking into a potentially dangerous, though much less frequent, problem that has recently caused major disruptions in flight schedules: volcanic eruptions. Ash and tiny, jagged particles are expelled from explosive volcanic eruptions. These particulates can be blown thousands of miles away from their source and are dangerous to airplanes,...

Improved Eruption Forecasts May Come Via Costa Rican Volcano Study
2013-08-01 07:54:55

April Flowers for redOrbit.com - Your Universe Online Compared to the geologic timescales most volcanoes operate on, Costa Rica's Irazu has something of a short fuse. A new study, led by Columbia University's Lamont-Doherty Earth Observatory, suggests the 1960's eruption of Costa Rica's largest stratovolcano was triggered by magma rising from the mantle over a few short months, rather than thousands of years or more, as many scientists have thought. The study, published in Nature, is...

Volcano Monitoring Program Searches Iceland For Early Signs Of Eruptions
2013-05-23 13:49:01

Lee Rannals for redOrbit.com — Your Universe Online A new collaborative project called FutureVolc is aimed at trying to improve monitoring of Iceland's volcanoes. FutureVolc started October 1, 2012 and is funded by the Environmental/FP7 program of the European Commission. The project says its main objectives are to establish an integrated volcano monitoring system through European collaboration, develop new methods to evaluate volcanic crises, increase scientific understanding of...

Iceland's Hekla Volcano Shows Signs Of Activity, No Eruption Imminent
2013-03-27 11:18:32

Lawrence LeBlond for redOrbit.com - Your Universe Online One of Iceland´s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak. Geologists at the Icelandic Met Office reported unusual seismic activity on the mountain over the past two to three weeks, but said there was no sign that an eruption was imminent. The...

The Smell Of Grímsvötn
2012-09-05 12:11:57

While piloting a commercial transatlantic flight last year, Captain Klaus Sievers and his crew got a whiff of an unusual odor. In a confined space 10 km up in the air, there was only one thing it could be. The foul smell with traces of sulphur in the cockpit came from none other than the Grímsvötn volcano that was spewing gas and ash from southeast Iceland. Sulphur dioxide often indicates volcanic ash, and the presence of ash in the atmosphere can endanger jet...

Exposure to volcanic ash can increase respiratory symptoms such as an extreme cough, or phlegm, according to a new study. The research, which will be presented today (4 September 2012) at the European Respiratory Society's Annual Congress in Vienna, investigated the effects of living close to the Icelandic Volcano, Eyjafjallajökull. Eyjafjallajökull erupted in April 2010 and created a huge ash cloud which spread across Europe, causing widespread disruption to...

Potential Eruption In Iceland Could Pump Acid Into European Airspace
2012-06-12 15:11:11

A modern recurrence of an extraordinary type of volcanic eruption in Iceland could inject large quantities of hazardous gases into North Atlantic and European flight corridors, potentially for months at a time, a new study suggests. Using computer simulations, researchers are investigating the likely atmospheric effects if a “flood lava” eruption took place in Iceland today. Flood lava eruptions, which stand out for the sheer amounts of lava and sulfurous gases they release and...

Icelandic Volcano Ash Results Presented 2 Years After Eruption
2012-05-14 07:44:35

In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. At the time, scientists followed its paths using satellites, laser detectors, sun photometers and other instruments. Two years later they have now presented the results and models that will help to prevent the consequences of such natural phenomena. The eruption of the Eyjafjallajökull in the south of Iceland began on...

Eyjafjallajökull
2014-04-08 13:12:23

Eyjafjallajökull is an active stratovolcano that is located in Iceland and is covered by an icecap. It reaches an elevation of 5,417 feet and the ice cap covers an area of thirty-nine square miles. This volcano sits on a magma chamber that is powered by the Mid-Atlantic Ridge and is comprised of andesite and basaltic lavas. The long name of this volcano is a combination of Icelandic words that mean “islands,” “mountains,” and “icecaps.” Although most of its eruptions are...

Katla Volcano
2014-04-08 11:22:12

Katla Volcano, also known simply as Katla, is an active subglacial volcano that is located in southern Iceland. It reaches an elevation of 4,961 feet and encompasses an area of 230 square miles, making it one of the largest volcanoes in Iceland. Its caldera reaches a diameter of six miles and it is occasionally somewhat covered by the Mýrdalsjökull glacier. The volcano was named for its kettle like shape and its name is often given as a female first name. Katla is thought to have...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
