Sakurajima volcano (Japan): new vulcanian explosion
http://www.volcanodiscovery.com/sakurajima/news/56293/Sakurajima-volcano-Japan-new-vulcanian-explosion-this-morning.html

After several months of unusual calm, the volcano had a moderately strong vulcanian explosion from the Showa crater this morning. An ash plume rose to approx. 10,000 ft (3 km) altitude.

Until the end of Sep 2015, Sakurajima had been producing such explosions, of varying intensity, at rates of typically 3-5 or more per day. This activity ceased around 28 Sep 2015 and until now, the volcano had only manifested surface activity in the form of minor ash emissions, degassing, as well as, very rarely, minor explosions. Whether the volcano is back to its previously typical behavior with more frequent and stronger explosions, as it had been during most of the recent years, remains to be seen.

One of Japan's most active volcanos erupted spectacularly Friday evening with a fiery blast that sent lava rolling down its slope.

Japan's Meteorological Agency said Sakurajima on the southern island of Kyushu erupted at around 7 p.m. (1000 GMT).

Japanese television showed an orange burst out of the side of the volcano, near the summit, accompanied by lightning-like flashes. Dark gray smoke billowed into the sky.

The Meteorological Agency banned entry to the area, expanding an existing no-go zone around the crater to a 2-kilometer (1.2-mile) radius, according to public broadcaster NHK. There were no immediate reports of injuries.

Friday's eruption, while dramatic, was average compared to Sakurajima's past eruptions, Kyoto University volcanologist Kazuhiro Ishihara told NHK. The mountain's last major eruption was in September.

He said rocks spewing out of the crater were expected to fall within the 2-kilometer (1.2-mile) zone from the crater. Smoke and ash rose 2 kilometers (1.2 miles) into the air, about half the height measured in 2013 in one of the mountain's biggest explosions in recent years, he said.

"I don't think there will be any serious impact from the explosion," Ishihara said. "But of course we must keep monitoring the volcanic activity."

The Japanese archipelago sits atop the Pacific "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin, and has more than 100 volcanoes. The 2014 eruption of Mount Ontake in central Japan killed 57 people.
 
Re: Colima's volcano recent activity

Latest news from Colim'as volcano was that, they discovered a grow of the lava dome so authorities, civil protection, and researchers had a meeting a couple of days ago to ... be prepared for whatever outcoming.

_http://lechaudrondevulcain.com/blog/2016/03/02/march-02-2016-en-fuego-telica-momotombo-masaya-colima/ said:
The National System of Civil Protection has confirmed the growth of a lava dome, with a low extrusion rate in the crater of Colima volcano. With an overflight conducted Monday (29), the Civil Protection has noted an increase in the size of the lava dome and an increase in fumarolic activity in the South-East.

In parallel to the monitoring and observation of the Volcan de Fuego, in recent days, there has been a seismic activity that is associated with the rise of magma, with a very typical fumarole activity to the rise of magmatic material indicated Civil Protection through a statement.

The agency added that the northern flank of the fumarole temperatures have maintained a high level compared to other years, and continues to record a slight glow on top of the volcano.

Therefore, the National System of Civil Protection, reiterated to the public that the exclusion zone for all kinds of activity is 5 km radius around the crater, except Montegrande canyon, which is 12 km, this because of the temperature in the pyroclastic flow. Avoid staying in the ravines near the volcano, because of the sudden and violent rains can trigger lahars.

Giant gas emitting dome found between Mount Vesuvius and the active caldera

Briefly covered here: http://www.sott.net/article/127611-Volcano-Ground-Rising-Near-Naples-Italy

Giant gas emitting dome found between Mount Vesuvius and the active caldera Campi Flegrei

A giant underwater dome covering an area of 25 square kilometres and having a height of about 15 meters was discovered halfway between the volcano Mount Vesuvius and the active caldera of Campi Flegrei, at depths ranging from 100 to 170 meters just 5 km apart from the port of Naples, Italy.

Scientists are actually concerned by the gas released by this new underwater structure and concluded that seabed doming, faulting, and gas discharge are manifestations of non-volcanic unrests potentially preluding submarine eruptions and/or hydrothermal explosions.



Scientists have discovered a dome releasing gases in the Bay of Naples, between the volcano Mount Vesuvius and the active Campi Flegrei caldera during the oceanographic campaigns.

The dome covers an area of 25 square km and has a height of about 15 meters. The new structure sits at depths ranging from 100 to 170 meters.

The findings made on the oceanic research vessel “Urania” show 35 gas emission spots and 650 small craters linked to the gas emission on the dome, which date back to 12’000 years.

According to the scientists, gas emissions in the Bay of Naples are secondary volcanic phenomena, but are not currently associated with a direct ascent of magma.

So we can not talk about magma rising at the surface, but there is evidence in other cases that such gas emissions preceded by hydrothermal explosions and the formation of underwater volcanoes.

Here the abstract of the Nature article:

We report evidences of active seabed doming and gas discharge few kilometers offshore from the Naples harbor (Italy). Pockmarks, mounds, and craters characterize the seabed. These morphologies represent the top of shallow crustal structures including pagodas, faults and folds affecting the present-day seabed. They record upraise, pressurization, and release of He and CO2 from mantle melts and decarbonation reactions of crustal rocks. These gases are likely similar to those that feed the hydrothermal systems of the Ischia, Campi Flegrei and Somma-Vesuvius active volcanoes, suggesting the occurrence of a mantle source variously mixed to crustal fluids beneath the Gulf of Naples. The seafloor swelling and breaching by gas upraising and pressurization processes require overpressures in the order of 2–3 MPa. Seabed doming, faulting, and gas discharge are manifestations of non-volcanic unrests potentially preluding submarine eruptions and/or hydrothermal explosions.

«Più che il “duomo” nel Golfo mi preoccupano i Campi Flegrei»

Il vulcanologo: “Il “duomo” nel Golfo di Napoli? Mi preoccupano i Campi Flegrei. Lì c’è qualcosa che si muove. E non c’è un piano”



Published on 1 Mar 2016

«Un duomo sottomarino è una struttura morfologica che corrisponde essenzialmente a un rigonfiamento sul fondo del mare. Quello scoperto nel golfo di Napoli è dovuto alla risalita di gas, prevalentemente anidride carbonica, una composizione non dissimile si ha nelle fumarole dei Campi Flegrei o del Vesuvio, ma con la differenza che qui si tratta di gas freddi, cioè non ad alta temperatura che risalgono attraverso condotti verticali da 50 a 100 metri». Lo dice al Mattino Guido Ventura, dell'Ingv di Roma, tra i coordinatori della ricerca pubblicata su Nature.


 
Re: Colima's volcano recent activity

http://www.sott.net/article/315349-Mexicos-Popocatepetl-volcano-erupts-again and so Colima's volcano, not so strong, although it had been ongoing ...

And I think I got an unidentifying object at Colima's volcano at webcamsdemexico.com site from today. Unless it would be the same fluff/dust in the lens, but I doubt it.

Add: both webcams are situated at different locations, one at Laguna de Carrizalillo, Col (first and third image)., and the other at the city of Colima (Panoramica ---the second image)

What is the bright "thing" that seems to come from thin air to its right, at second 2 (more visible), a plasma discharge or? ... at the end looks like pouring out lava like substance ...

Yeah, it surely looks like some kind of a bleedthrough from another dimension. :huh: :)
 
Re: Colima's and Popocatepetl's volcanoes activity

Another great explosion had yesterday the Popocatepetl

It appears again at the same place, perhaps is just some sort of a glitch reflection of the webcam...

Colima's, from earlier today.

Re: Colima's volcano recent activity

It got my attention one image of Colima's volcano at strangesounds FB, from 9 of April, according to the site, Colima's volcano release two fumaroles (Jets of hot gas and water vapor), well is just that is the first time I noticed that detail.

Re: Colima's volcano recent activity

Here is a short video of the ash cloud covering the population in Puebla:

Huge Ash Cloud Rolls Through Puebla Following Popocatepetl Eruption
http://www.liveleak.com/view?i=a1c_1461084614

Mexico’s Popocatepetl volcano erupted overnight on Monday, April 18, covering the nearby town of Puebla in ash and shutting down its airport . The volcano hurled hot rocks up to a mile from its crater and emitted an almost two mile high column of steam and ash. This video shows the massive ash cloud rolling in over the town.



Efforts to monitor a spike in Mount Aso's volcanic activity are in disarray after the recent earthquakes and aftershocks in Kumamoto Prefecture.

Quakes disable devices to check volcanic activity on Mount Aso
http://www.asahi.com/ajw/articles/AJ201604190065.html

Power outages caused by the seismic jolts that began April 14 mean that monitoring devices on the mountain are unable to transmit data, leaving experts with few means to gather information on a possible impending volcanic eruption.

This grim situation came to light April 18 during a meeting of a task force to deal with earthquakes and volcanic eruptions set up under the Ministry of Education, Culture, Sports, Science and Technology.

The Japan Meteorological Agency, Kyoto University, the National Research Institute for Earth Science and Disaster Resilience (NIED) and other institutions, operate observation facilities on the mountain in northeastern Kumamoto Prefecture.

These facilities use equipment such as seismometers and inclinometers to gather data.

A task force official reported to the April 18 meeting that a staff member at Kyoto University’s Aso Volcanological Laboratory evacuated the facility because of earthquake damage.

Participants at the meeting also learned that landslides triggered by the quakes have blocked road access to the site.

Equipment at an observation facility operated by the NIED was also knocked out of action due to power outages and other reasons.

According to an official of the Japan Meteorological Agency, six seismometers set up around Mount Aso's crater could not transmit data temporarily.

However, the official said there were “no problems” in the observations of the volcano because of data from inclinometers and the Global Navigation Satellite System (GNSS), which monitors crustal movements.

“We are seeking the cooperation of relevant institutions so that the equipment can be restored as soon as possible,” said Hiroshi Shimizu, a professor of seismology at Kyushu University, who heads the task force.

The importance of closely monitoring Mount Aso heightened after a small eruption on April 16, hours after a 7.3-magnitude earthquake hit Kumamoto Prefecture.

Very cool!

I wonder if there is any history of earthquakes at a distance preceding or following eruptions of Etna or Vesuvius? Like in Europe anywhere?
