There were eight events and five explosions at Minamidake crater from June 4 to 11. Crater incandescence was occasionally visible at night. Ash plumes rose up to 2 km (1.2 miles) above the crater rim, except during an event at 11:35 JST on June 10 which produced a plume that rose 3.5 km (2.1 miles). Tephra was ejected as far as 1.3 km (0.8 miles) from the crater between June 8 and 11.

The Japan Meteorological Agency maintains the alert level at 3 of 5 since February 5, 2016.

Volcano on Rome’s doorstep is slowly reawakening

Increased activity below the earth’s surface suggests volcano just 10km from the Italian capital is getting close to another eruption.

In a study published in the journal Geophysical Research Letters, an international team of researchers reported that the ground in the region is rising by 2-3mm per year and underground chambers located several kilometres below the towns of Ariccia, Castel Gandolfo and Albano are filling up with magma – signs that the previously dormant volcano is rumbling back to life.

Satellite imagery and seismographic charts also record the volcano’s slow awakening.

Five Volcanoes Erupting at Once April 16, 2014

Remote. Cold. Rugged. Those three adjectives capture the essence of Russia’s Kamchatka Peninsula. Another word—perhaps more applicable than anywhere else on Earth—is “fiery.”

Of the roughly 1,550 volcanoes that have erupted in the recent geologic past, 113 are found on Kamchatka.Forty Kamchatkan volcanoes are “active,” either erupting now or capable of erupting on short notice. TheOperational Land Imager (OLI) on Landsat 8 captured activity at five of them during a single satellite pass on April 14, 2014.

From geographic north to south (and top to bottom on this page), the volcanoes are Shiveluch, Klyuchevskaya,Bezymianny, Kizimen, and Karymsky. The tallest of the group is Klyuchevskaya, a stratovolcano with a steep, symmetrical cone that reaches 4,750 meters (15,580 feet) above sea level. The most active is Karymsky, a 1,536-meter (5,039-foot) peak that has erupted regularly since 1996.

Plate tectonics is responsible for the many volcanoes on Kamchatka Peninsula. The Pacific Plate is slowly colliding with and sliding beneath the Okhotsk Plate. As rock from the Pacific Plate descends and encounters higher pressures and temperatures, it melts into magma. Over time, magma accumulates and migrates up toward the surface, causing volcanic eruptions.

Long before the discovery of plate tectonics, Kamchatka’s many volcanoes and eruptions were woven into a rich tapestry of myths and creation stories. According to Koryak folklore, the raven-like deity Kutkh created Kamchatka by dropping a giant feather on the Pacific Ocean.

Each of the first generation of men became one of Kamchatka’s mountains at death; many of these mountains became volcanic because the men’s hearts burned so passionately for a beautiful woman that Kutkh had also created near the beginning of time.

In 2013, another NASA satellite collected imagery of Shiveluch, Bezymianny, Tolbachik, and Kizimen.

And more volcanoes erupting in South America……

ECUADOR: Video of a dangerous Tungurahua eruption pyroclastic flow 01-02-2014

Posted in 2014 with tags , , , , on February 4, 2014 by theboldcorsicanflame

The video below shows very well how a pyroclastic hot cloud descends from the volcano slopes and continues further and further. At the end the cloud arrived closer and closer to the video recording people

The Ecuadorian Civil Defense authority has called the Orange alert for a limited number of villages on the slopes of the volcano. Hundreds of people living in these villages have received the order to evacuate. Especially the extremely hot pyroclastic flows are a big risk for these communities.
The city of Banos, at the foot of the big volcano, has received instructions to prepare for a possible evacuation if the current situation would deteriorate.

Volcano Etna: Explosive Activity November 6th 2013/ Attività esplosiva

Posted in 2013 with tags , , , , , on November 7, 2013 by theboldcorsicanflame

On the morning of November 6th, 2013,  on the top of the craters of the assets volcan del’umanità appeared a veil of white snow. Around minerai 13,00 have been reported puffs of volcanic ash from the NCSE.

Such a weak activity, followed by the roar of the explosion also heard from the foothills centers, it happened also during in the  afternoon.

The explosion Shooting is that of minerai 15:14.
Recall that in the days preceding this, there were two series of seismic swarms which occurred on the side of the South West of Volcano (municipalities of Belper, SM Licodia, Adrano)

Bernhard Edmaier, born in 1957, had been a geologist before he made photography his profession 20 years ago and founded a photographic agency ‘Geophot – Pictures of the Earth’. He lives in Ampfing near Munich, Germany.

Geology constitutes the basis of his photography. It is his aim to present the manifold colours, forms and structures which the Earth has created without man’s interference. The technique he uses in his work is aerial photography.

Driven by his perennial interest in natural phenomena, Bernhard Edmaier travels extensively to deserted and still untouched corners of the globe to gather material for his books and other photographic projects. On his trips, he is accompanied by Dr Angelika Jung-Hüttl, his partner, fellow geologist and science writer for prominent German newspapers and popular science magazines, who in close co-operation with the photographer, works on book projects and provides scientific commentaries for his photo book editions.

Over the years, Bernhard Edmaier has won many prestigious awards for his work. His volumes of photography ‘Vulkane’ (1994), ‘Eisige Welten’ (1996) and ‘Geoart Deutschland’ (2003) were consecutively voted The Most Beautiful German Science Book of the Year, and his ‘Geoart – Kunstwerk Erde’ won him a renowned Kodak Photo Book Prize in 1998. In 2001 he received the Hasselblad Master Award.

Volcanoes/History: The Great Eruption of the Tambora in Indonesia in 1815

Posted in Uncategorized with tags , , , , , , on July 4, 2011 by theboldcorsicanflame

The volcano Tambora, in the Indonesian island of Sumbawa, blew up in April 1815. It was the largest explosion ever recorded on Earth. There was no summer in 1816 because of the volcanic dust that obscured the Sun. Crops failed and livestock died causing the worst famine in the 19th century.
