The use of drones in all fields entered in the uses. It is undeniable that these provide an approach to volcanic phenomena without direct risks for the user, and a surprising images harvest. (See the article ""Drones de volcans"" 04.2013)

This will not be the case in Yellowstone National Park or in other areas controlled by the National Park Service, where they are, from June 2014, forbid by the interest of public safety, disruption of wildlife and potential impacts on visitors and staff.

Notice regarding "Unnamed aircraft" - Doc. Yellowstone National Park

Despite this prohibition, a number of recent incidents in Yellowstone National Park led the authorities to crack down harder.

On 17 July, a drone was damaged in the Yellowstone Lake, near the marina in West Thumb. Its German owner is charged with prohibited use of aircraft flying, false statements, and commercial image taken without permission.

On 2 August, a drone crashed in the Grand prismatic ... his Dutch operator, although cooperating with investigators, is considered violating several federal laws, and risk $ 5000 fine and / or six months imprisonment and / or five years' probation.

On August 19th, an American was charged of prohibited overflight above the Midway Geyser Basin, too close to the bison.

Other incidents were reported in Grand Teton Park nearby, but also in Yosemite and the Grand Canyon of the Colorado.

We must remember that the hot springs of Yellowstone are fragile sites, and a remarkable habitat. The slightest disturbance can cause irreversible changes in some cases.

That may have caused damage as the input of a drone in a hot spring at 160 ° C as the Grand Prismatic? ... What kind of change can happen by leaving it in place, or even getting to remove it?

Prohibition of drones in American National Parks.

Just remember the changes in feeding and water temperatures occurred in Morning Glory Pool by introduced waste, leading to a modification of thermophilic and therefore a change in color of this hot spring. (see previous article: "Morning Glory ... nostalgie automnale" ).

The drones are valuable investigative tools, but their unregulated and sometimes outrageous use should not be admitted.

Disney Insider notes that Uku is "a wonderful example of the art of modern animation, the film depicts the tropical fauna and flora with an incredible level of realism."

James Ford Murphy notes that the idea of ​​this short film came to him during his honeymoon there twenty years. He was so taken by the Hawaiian culture that he began to play the Ukulele, and ended up writing the music for this film.

"The whole thing was an exercise in contrast," said Murphy. "Volcanoes are so destructreurs, but they are so creative. They are incredibly powerful in their eruptions, but they are so peaceful in other times."

What to salivate ... until June 2015, when the U.S. release

In 2005, the Vestmannaeyjar City Council has approved the excavation project of 10 houses buried in 73, and the construction of a visitor center.

This project was named "Pompeii of the North". The excavation is still ongoing, mechanically and manually, but instead of being ruined, many houses have walls intact, some covered with their original paint.

The Eldheimar museum was built around Gerðisbraut 10, home of Guðni Ólafsson, and his family, who became the centerpiece.

On 1,000 sqm, the exhibition and its interactive multimedia show tell the eruption of 1973, and the life of the inhabitants of Heimaey.

This exhibition also covers the eruption of Surtsey, the new island that emerged following the 1963 eruption south of Heimaey.

The Mercalli year begins on March 19 in Italy ... various ceremonies commemorating the centenary of his death.

Seismologist , volcanologist and clergyman , Giuseppe Mercalli is known to have developed a scale of earthquake intensity , bearing his name, and a classification system for volcanic eruptions.

Centenary of the death of G.Mercalli

Born in 1850 in Milan, Mercalli is also studied there. Father Stoppani teaches him geology. He began teaching at Monza, then Reggio di Calabria (1885) and from 1892 , in Naples. He succeeds Matteucci as director of the Vesuvius Observatory in 1911 . He spends the rest of his life to the study of this volcano .
He died mysteriously in 1914, burned in a fire in her apartment.
His most significant contribution is his work on the scale of seismic intensity .

Although some seismographs are available, the largest part of information of Mercalli is his personal observations of the damage caused by earthquakes.

He first developed an intensity scale ( subjective ) to six degrees, but quickly realizes she lacks of precision. In 1902, he changes the scale of ten degrees of Rossi- Forel , by adding a detailed description of each degree. This new scale is unanimity among scientists of the time . Other seismologists continue this work : Cancani leads to 12 degrees and Sieberg restates the descriptions , but the scale will continue to bear the name of Mercalli .

Giuseppe Mercalli also catalog the Italians earthquakes, in his book "
I vulcani e fénomeni vulcanici in Italia" ... he believes that " to understand an earthquake, it is necessary to know the regional seismic history."

His reputation of seismologist made him to ​​travel to Spain in 1884 , where he examines the aftermath of the earthquake in Andalusia. In 1887, he is the principal investigator of the earthquake on the Ligurian coast between Menton / France and Imperia / Italy. This major disaster caused more than 600 deaths , hundreds of injuries and widespread destruction in the villages of the hinterland .

Mercalli also extensively studied volcanic activity and released "
I vulcani attiviti delle Terra " , a catalog of volcanoes in the world , where he developed a scale to compare the eruptions.
