This Week in Volcano News; Danger of a Large Eruption at Masaya; Iwo Jima Erupts

Рет қаралды 104,227

Күн бұрын

There is a risk that a large volcanic eruption could occur in Nicaragua at the caldera volcano known as Masaya. Elsewhere in the last week, a new volcanic eruption began at the Iwo Jima volcano. And, in Japan, the Hokkaido-Komagatake volcano produced an unexpected volcanic tremor which occurred alongside changes in inclinometer readings. This video will discuss these stories and list the 47 volcanoes which are currently erupting around the planet.

Minor correction since I have seen this mistake in multiple news outlets. The new volcanic island at Iwo Jima (Iōtō) was not given any name - it is most certainly not "Niijima". Niijima is a different and completely unrelated populated island that can be seen from the main island of Honshu. The Japanese news outlets referred to the newly formed island at Iwo Jima simply as a "新島" or "new island" pronounced "shin tō". This is not a name - it just means "a new island". The confusion stems from the fact that both Niijima and shin tō are written 新島 in kanji. The difference between the two and the correct pronunciation is obvious to Japanese because of the context, but it seems that foreign news outlets did either some Googling or some machine translating and came up with the pronunciation of Niijima. Fortunately for the residents there, there is no volcanic eruption on Niijima and there has not been one since the year 886.

The Black Lava one, the Ol Doinyo volcano in Tanzania is the only one in the world right now. There have been others in the past, but that type of lava doesn’t preserve well through time so we don’t find much of it. Most carbonatite lava currently is only intrusive, meaning it doesn’t come to the surface. Ol Doinyo is really unique.

the beaches that americans landed on are like 30 something meters above where they were in the 1940s. its not from eruptions building an edifice so its just influxes of magma and gases pushing the floor up. and has been ongoing for a long time probably. sea level rise in the last 10ky could have played a factor in adding weight to the edifice and cooling the crustal material while magma builds and pressurizes and its probably got rhyolite or dacite components since its been so long without anything bigger than the random phreatic eruption.

@Dragrath1 2 ай бұрын

@@Iambrendanjames Given the erupted lava is Trachyandesite it's main siliceous component is probably trachyte the more alkaline counterpart to dacite or something closer to that as magma mixing can be extremely complicated. The behavior is pretty similar as it is a high silica magma just one with an enrichment in some more alkaline minerals

Have humans ever taken measures to help reduce excessive pressure in a volcano showing conditions that make it unusually hazardous? Thanks for your videos.

@MrPeabody67 2 ай бұрын

In theory you wouldn't want to do that because relieving pressure can cause new melt. Alot of magma chambers are in this weird state in that they're technically hot enough to be molten, but the pressure keeps most of the magma in a more "plastic" state. In explosive eruptions, once that pressure gets released violently, most of the inactive chamber becomes fresh melt and joins the eruption.

@michaeldeierhoi4096 2 ай бұрын

@@MrPeabody67 That is a good point often over looked by people speculating about relieving pressure and thus the likelihood of an eruption which in fact in worst case scenario cause an eruption. As I understand it reducing the pressure could cause an increase in gases coming out of solution increasing the pressure again which would increase the possibility of an explosive eruption.

@@michaeldeierhoi4096 I didn't think about additional degassing. That then made me think about the fact that meteoric water would start to go down the hole you drilled, forming a hydrothermal field that could weaken a flank of the volcano.

@michaeldeierhoi4096 2 ай бұрын

@@MrPeabody67 Thanks for raising that point. The reality is the drill hole goes down about a km. The magma sill sits at 5 km with a stable rock layer above it and so the geothermal activities have been studied in Iceland and elsewhere and no impact on causing or aggravating volcanic activity has ever been found. The biggest reason which I alluded to is because they occur at some distance apart from each other underground.

@@michaelhaywood8262 It's not about being close to a major population centre, it's about the potential far-reaching effects of Iwo-Jima. It is a tropical volcano that is capable of a VEI6 or 7 eruption which would generate tsunami across the entire Pacific basin and potentially a volcanic winter like we haven't experienced in over 150 years. A full-on, global volcanic winter could kill millions of people and potentially even collapse society.

Would you know why the carbonatite lava is black in the beginning in the first place? Molten carbonates are still white or maybe glowing red.

@michaeldeierhoi4096 2 ай бұрын

Carbonitite lava is definitely about the weirdest lava on the planet for several reasons. It only has a 3 % silica level thus an extremely low viscosity compared even to basalt which is at least 45% silica. Here is an excerpt from a wired magazine website explaining what you are asking though I'm not sure how I would rephrase it as it isn't clear to me. "Carbonatite lavas even weather differently than silicate lavas. They are composed on carbonate minerals like calcite (or even strangest minerals like nyerereite and gregoryite), so when exposed to water or even humid atmosphere, they break down quickly. This gives Oldoinyo Lengai its unique coloration, where dark carbonatite lavas erupt black to grey but after cooling at weather, appear stark white".

But, to apply simple logic, if CME’s influence volcanism on earth, then simply look at the strongest CME to hit earth and look at volcanic activity from the same time frame. The late 1859 Carrington event was caused by an extremely powerful CME hitting the earth, it is the strongest CME event to hit the earth in the last 160 years. It was so powerful it disrupted telegraph lines all over the world. There were no eruptions of note in 1859. There were only two category 4 eruptions in the 1860s as a whole, less than in either the 1850s or the 1870s. So if anything, this would indicate CME impact correlates with reduced volcanic activity, lol.

@michaeldeierhoi4096 2 ай бұрын

Volcanoes only have an affect on lowering the climate temperature in particularly large eruptions. Mt Pinatubo in 1991 was particularly explosive in produced over a km³ of tephra and injecting an enormous quantity of SO2 into the upper atmosphere so as to cool the climate about 1° F for a year. Other significant examples were Tanbora in 1815 and to a much lesser degree El Chichon in 1982. Large eruptions are thought to have played a role in the Little Ice Age but they are the exception not the rule in volcanic eruptions. Since human burning of fossil fuels continues to produce on the order of 36 BILLION tonnes of CO2 into the atmosphere every year the climate has gradually retained more heat thus gradually warming the climate. Volcanoes produce approximately 1% of the total CO2 produced by humans in a given year. This is all well documented information available online.
