Mexican Volcano Puts On Breathtaking Lightning Show

VOLCÁN DE COLIMA DOING ITS THING

Mexico’s Volcán de Colima has been erupting rather spectacularly as of late. This particular mountain has had a long history of violent explosivity, but in the last few years, this stratovolcano has been picking up the pace somewhat by exhibiting near-continuous eruptive activity.
Thankfully, the volcano is being permanently monitored by scientists, emergency services, and webcams. It’s also caught the eye of photographer Sergio Tapiro Velasco, who managed to capture this unbelievably stunning image of volcanic lightning leaping forth from the tip of a plume of ash.
Volcanic lightning is a phenomenon that has yet to be definitively explained. Conventional lightning appears when a layer of warm air mixes with a layer of colder air, normally within clouds. This tends to produce an electrostatic charge, with the upper segment of the cloud having a positive electric charge and the lower segment having a negative one.
For a while, the insulating capacity of the air stops the charge imbalance from correcting itself. When the charge builds up to a certain level, however, the insulation breaks down as a flash of lightning appears, balancing out the charge in the air, albeit temporarily.
Within a volcanic cloud, researchers think that lightning appears from the base of the magma within the volcano’s vent. The churning action seems to electrify the ash and lava blebs floating around in the cloud right above it.
This allows charge to accumulate, and, just like within a normal water cloud, lightning appears when the charge imbalance becomes too strong. Generally speaking, the larger the ash plume, the more frequent the volcanic lightning.
So that’s the basic science that could be behind this beautiful light show. If you want to see it for yourself, we’d suggest going to Japan’s Sakurajima, where you can see it several times a month in some instances.

Mexico's Colima volcano erupts again
One of Mexico's most active volcanoes has erupted, yet again.
Colima — known locally as the volcano of fire — spewed gas and ash into the air on Wednesday. An ongoing volcanic ash advisory, issued by the Volcanic Ash Advisory Center in Washington, remains in effect Thursday.
The volcano is in western Mexico, about 160 kilometres south of Guadalajara. Its eruptions date back to the 16th century, but have been steady since 1994.

The activity has intensified since last October, when nearby residents were evacuated as the volcano spewed lava. It is part of the Pacific Ring of Fire, the 40,000-kilometre volcanically volatile area home to about 75 per cent of the world's active volcanoes.
Colima's recent eruptions have created some lava domes, made from lava that has built up around the volcano's opening.
I always thought volcanos were fascinating as a kid when I read about Pompeii
I used to love reading about that.
VOLCANOES ERUPTING ALL OVER THE WORLD: IS SOMETHING HAPPENING TO THE EARTH’S CORE?
KALEE BROWN MARCH 3, 2017

You may have already seen the headlines: Italy’s Mount Etna recently spewed an impressive amount of lava during what is now its second eruption within the last year. Mount Etna represents Europe’s biggest and most powerful volcano, and its eruption poses a hazard to air traffic and potentially the surrounding villages and homes on the lower slopes of the volcano.
Volcano eruptions aren’t as rare as many people assume them to be. Although Mount Etna is the latest volcano to make big headlines, there are numerous other eruptions occurring all over the world. Volcanoes are erupting practically everywhere: India’s only volcano is active again after 150 years, and four of Iceland’s main volcanos are expected to erupt soon, to name a few. This begs the question: Is something happening to the Earth’s core?
Which Volcanoes Are Erupting or Are Dangerously Close?
According to Volcano Discovery, 35 volcanoes are either currently erupting right now or just recently erupted all over the world. There are even more volcanoes with eruption warnings and tons of other volcanoes that are active, meaning they could technically erupt at any minute (though unlikely).
According to USGS: “Scientists use the term magma for molten rock underground and lava for molten rock (and contained gases) that breaks through the Earth’s surface.” At the moment, something in the Earth is causing magma to be pushed up in numerous volcanoes worldwide.
One of the latest eruptions was Mount Etna. On February 27, 2017, the active volcano, located on the Eastern coast of Sicily, Italy, erupted. The volcano stands tall at 3,329 metres, representing the largest active volcano in all of Europe. The city declared a a yellow alert and, as recommended by the municipal emergency plan, issued an ordinance restricting anyone from visiting the volcano. Although there were no casualties, the eruption is still cause for concern, sparking fear around the city.
Barren Islands volcano, India’s only active volcano, just recently became active again after being dormant for the past 150 years. It erupted for four hours in January 2017. This volcano is particularly old, as its first eruption dates back to 1787. But what woke it up?
According to geophysicist Páll Einarsson, four of Iceland’s main volcanoes are showing more and more activity, indicating that they will erupt very soon. One of these volcanoes, Katla, is the most active its been in the past four decades.
Earlier this month, Indonesia’s Mount Sinabung in north Sumatra province erupted seven times over the course of a single day. Tourists and locals in the area are wearing eye, mouth, and face masks in order to prevent direct exposure to the volcanic ash, and thousands of villagers were displaced. At the time of the eruption, Mount Sinabung represented the tenth volcanic eruption over the course of a week.
On February 25, 2017, Guatemala’s Volcano of Fire erupted as well. This was actually the second time it had erupted already this year. The Kilauea volcano in Hawaii produced what locals are calling a “firehose” of lava on New Year’s Eve, which is still ongoing. There are numerous more examples of volcanoes erupting all over the world, some of them entirely unexpected.
To be clear, these volcanic eruptions have nothing to do with geographic location, as I’m sure you can tell, since Iceland and Indonesia are extremely far apart. It’s clear that something is causing an increase in worldwide seismic activity.

Just How Big Is This Increase in Activity?
Let’s take a look at the volcanic activity this century versus the previous one.
The enormity of the difference in numbers is absolutely astounding seen on the year by year graphs below
Even taking technology into account the difference is astounding
In 2011, the year of the mag 9. Fukushima disaster in Japan our planet suffered 208 major quakes compared to 1911 when just 11 were recorded.
Strange: while mag 6 to 6.9 quakes have risen over one hundred years by as much as 450% earthquakes measured at mag 7 or higher have remained increadibly stable over the same period

In the past, climate change has been known to cause volcanic eruptions. Over the past million years, during periods of extreme climate change, the rapid melting of continental glaciers has resulted in sea levels rising, which in turn increases the amount of volcanic eruptions. However, that’s likely not what’s happening here, as the eruptions don’t always take place immediately after the climate changes. There’s expected to be a lag time of at least a thousand years between the point at which the climate changes and then the resulting eruptions.
Even though it’s unclear why so many volcanoes are all of a sudden erupting, I think it’s crucial to understand the extent of the problem and to reflect on the changes we’ve made over the past few centuries.
There are numerous “super volcanoes” that could negatively affect and potentially kill millions of people, one of which is the “Campi Flegrei” volcano located in Italy. Many people forget how detrimental volcano eruptions can be; after all, the entire city of Pompeii was destroyed by one.
So, what changes have we made since all of these volcanoes started to erupt? It’s no secret that society as a whole treats the environment terribly; we dig it up, exploit its resources, and claim ownership of it only to destroy it. To me, from an energetic standpoint, these eruptions could be a reflection of the way we treat the environment. If you were being treated poorly and constantly exploited, would you implode, too?
Forgot why it happensthat volcano lightening looks nice
I'll live for ever my ninja, my carbon atoms never die.Mother Nature Jones Jr. says humans just tenants, not permanent residents.
think it's all the chemicals that float in the air causing other chemicals in the air to react..chemistry shit... i think it's 1 reason why they scared if them super volcanoes go off cause not only will they be darkness but wild ass stormsForgot why it happens
I wanna see that shitthink it's all the chemicals that float in the air causing other chemicals in the air to react..chemistry shit... i think it's 1 reason why they scared if them super volcanoes go off cause not only will they be darkness but wild ass storms
