The Italian night sky was glowing red yesterday after a massive eruption from Mt Etna.
The volcano, which is the tallest in the world, spewed hot lava and ash into the atmosphere for several hours on Tuesday night and Wednesday morning.
It is not believed that anyone was hurt by the eruption, though there are worries that increasing levels of activity from the volcano could presage a seriously destructive incident in the near future.

The Year Without Summer: 1816 and the Volcano that Darkened the World and Changed History By William K. Klingaman and Nicholas P. Klingaman 352 pages. St. Martin’s Press. $27.99.
As the ghastly weather of 1816 persisted, observers naturally tried to divine the cause of their distress. The favored explanation among the learned was Sunspots.
When a massive volcano exploded in 1816, it plunged temperatures around the world. Mark Hertsgaard on the eerie parallels between this catastrophe and climate change in our own time.
The terms “global warming” and “climate change” never once appear in this book, but in relating the history of a literally earth-shaking event that occurred 200 years ago, the authors of The Year Without Summer - Amazon Link: 1816 and the Volcano that Darkened the World and Changed History By William K. Klingaman and Nicholas P. Klingaman 352 pages. St. Martin’s Press. $27.99. -The Year Without Summer have described a past that resembles our present in ways so uncanny, so numerous and fundamental, that the reader can only hope that Marx’s dictum—history happens twice, the first time as tragedy, the second as farce—will turn out to be wrong this time around.
The earth-shaking event in question? Not a military battle, not the overthrow of a government, the invention of a revolutionary technology, or any of the other human-centric themes that preoccupy most history books. No, this event’s protagonists were natural forces: a volcano whose eruption was the most powerful in recorded history, and the many changes that the volcano’s smoke and ash triggered on this planet.
The volcano, named Tambora and located on the island of Java in what is now Indonesia, exploded on April 5, 1816. As superheated liquid rock and gas gushed down the mountainside, an estimated 12,000 local people perished within 24 hours.
But a far greater, and distant, death toll was yet to come. As the eruption’s detritus rose into the sky, it cohered into an aerosol cloud the size of Australia. Winds then blew this cloud westward across the continents, over Asia, Europe, and the Americas.

LIMA (Reuters) - Hundreds of small earthquakes have shaken the earth around the Sabancaya volcano in southern Peru over just a few days and the rumbling, along with plumes of smoke spewing up to 320 feet high, have put officials on alert to evacuate the area.
Peru's geological agency Ingemmet recorded some 536 quakes, about 20 an hour, on February 22 and 23 and periodic movement is ongoing.
Thousands of people live in the valleys surrounding the volcano. Some have already started to leave the region because the unusual seismic activity has damaged their homes. About 80 homes were damaged by one temblor on February 22, Peru's national defense office said....
..Ingemmet said the volcano has been releasing huge smoke trails intermittently since January 15 and current seismic activity is similar to that which accompanied an eruption in 1986.

On the 18th February SpaceWeather.com reported that the Sun had the most intense Solar Flare of the Year on the 17th February and I reported at the time there was nothing of any note that I could associate with this event. Well after two days of this Solar event taking place it looks as if Mount Etna decided to join the party!!!....and no, this time I do agree it's just a coincidence:)

A unique show is taking place on Kamchatka these days: Four separate but nearby volcanoes are erupting simultaneously on the Russian peninsula. A Moscow film crew has produced an awe-inspiring 360-degree video of the natural fireworks.
Volcanic eruptions are hardly a rarity. It seems that a new one goes off every few weeks or so somewhere in the world. But a string of four volcanoes erupting in close proximity to one another is virtually unheard of.
That, though, is what has taken place in recent weeks on the Kamchatka Peninsula in Russia's far east. Four different cones and mountains, all within 180 kilometers (110 miles) of each other, have been active simultaneously since late November. Given that volcano experts don't believe that the four volcanoes are being fed from the same magma source, the parallel eruptions would seem to be the geological equivalent of winning the lottery.
And, as a photography team from the Moscow-based Airpano discovered, the phenomenon presented a fantastic opportunity to produce some awe-inspiring images and videos. Indeed, the quartet of lava and ash-spewing peaks are so close to one another -- they lie within 180 kilometers (110 miles) of each other -- that that the film crew recently visited all of them in a single day.

Three volcanoes in Russia’s Kamchatka continue to send steam and ash into the air while lava flows down their slopes. Volcanic activity on the peninsula has dramatically intensified. Aviation authorities issued an orange security level in the area.
The volcanoes Shiveluch, Kizimen and Plosky Talbachek are erupting in different parts of the peninsula simultaneously, causing dozens of local earthquakes, as the vibrations accompanying the eruptions of the giants continue to increase.
The biggest and most active is Shiveluch, Kamchatka’s northernmost volcano and 3,283 meters high. Over the last days it made several eruptions of gases, steam and ash, the highest of which reached the 4,900m above sea level. Unceasing earth tremors send avalanches down its slopes. Sensors installed near the volcano are registering high seismic activity with, active gas generation and thermal anomalies.
Activity of Shiveluch started to grow back in 2009 when its dome split with a fissure 30 meters deep.
A mere 45km from Shiveluch there is Klyuchi settlement with 5,000 citizens. Volcanologists say at the moment there is no imminent danger to the town.

Details of around 2,000 major volcanic eruptions which occurred over the last 1.8 million years have been made available in a new open access database, complied by scientists at the University of Bristol with colleagues from the UK, US, Colombia and Japan.
Volcanic eruptions have the potential to cause loss of life, disrupt air traffic, impact climate, and significantly alter the surrounding landscape. Knowledge of the past behaviours of volcanoes is key to producing risk assessments of the hazards of modern explosive events.
The open access database of Large Magnitude Explosive Eruptions (LaMEVE) will provide this crucial information to researchers, civil authorities and the general public alike.
Compiled by an international team headed by Dr Sian Crosweller from the Bristol's School of Earth Sciences with support from the British Geological Survey, the LaMEVE database provides – for the first time – rapid, searchable access to the breadth of information available for large volcanic events of magnitude 4 or greater with a quantitative data quality score.

A late report has come through regarding Volcanic Activity after the CME I mentioned yesterday
The Tungurahua volcano seismic activity remains after yesterday's explosion -abc.es/agencia - Google translate Spanish/English
The Tungurahua volcano in central Ecuador Andean, today held a major seismic activity after the sudden explosion Friday, which raised a column of gas and ash seven kilometers on its summit.
The Geophysical Institute (IG) of the National Polytechnic School reported that in the last 24 hours the Tungurahua generated another small explosion, with a column of 2 kilometers, plus 74 minor earthquakes by fluid movement inside and two Vulcan tectonic rocks related internal fractures.
Tungurahua volcano (Ecuador): sudden strong explosion - volcanodiscovery.com
A sudden strong ash explosion occurred at Tungurahua volcano in Ecuador today at 14:35 local time. According to local reports, the eruption produced an ash plume rising to 6 km altitude and was visible from Ambato, Riobamba, Pelileo and Patate. The explosion followed an increase in seismicity over the past days.

If ever there was a Sunspot number that I will remember it's going to be AR 1618. This was the very area on the surface of the Sun that was going to be the second November "R5", it ended up being an anti-climax to say the least, but when it did Eurupt after a delay of 5 - 6 days. The location of AR1618 was just going off to the far side of the Sun it was then called the solar flare with a "last gasp"! as per SpaceWeather.com report. The Solar Flare was NOT facing Earth at the time but there would seem to be a hole facing Earth!
I went on to try and connect the solar event with a very rare Tornado in Italy and also made the connection to the early Tropical Storm development of Typoon "Bopha" to Cat1
Today NASA have published aerial images from a Volcano in Russia that suddenly burst into life......on the 27th November, the same day as the AR 1618 Erupted on the surface of the Sun
...These astonishing aerial images captured by a NASA satellite reveal molten lava spewing from a Russian volcano that suddenly erupted after lying dormant for 36 years.
The Plosky Tolbachik volcano on Russia's Kamchatka Peninsula burst into activity on November 27, sending clouds of ash almost 10,000 feet into the air, and leading some experts to warn it could go on to unleash an eruption as powerful as that seen from Iceland's Eyjafjallajokel in 2010, which caused more than a week of air traffic disruption...
