Ziet er altijd vaag uit ja, maar niet ongewoon. Ik was in Indonesie in een vulkanisch gebied en daar had je gewoon diepe gaten in de natuur (niks geen hekjes oid) waar zwaveldamp uit kwam. Als je te dichtbij kwam ging je direct over je nek. Maar soms liep er een weg langs en dan zag je idd dit op de plek waar de damp vaak neersloeg.

Vulkanische gebieden zijn mijn favoriete natuurplekjes. Er is altijd wel iets raars te zien. Borrelend modder, of knalgroene/gele/rode meren.

Hoe goed is jullie Zuid Afrikaans.
Die ANC-regering het ‘n versoek van die VSA van die hand gewys om deel te wees van ‘n Amerikaanse rampbestuursplan waaruit Suid-Afrika $10 miljard per jaar (ongeveer R100 miljard) vir tien jaar sou ontvang. Luidens die plan sou tydelike huisvesting vir miljoene Amerikaners in Suid-Afrika gebou word ingeval die Yellowstone-supervulkaan in dié land een of ander tyd tot uitbarsting sou kom.

Lande wat wel aan die Amerikaanse noodlenigingsplan gaan deelneem, is Brasilië, Argentinië en Australië. Volgens ‘n woordvoerder van die departement van buitelandse sake, dr. Sipho Matwetwe, sal Suid-Afrika nie “deel van die plan wees nie omdat daar ‘n risiko bestaan dat miljoene wit Amerikaners in ‘n noodsituasie na die land gestuur kan word en dit kan ons nasionale kultuur en identiteit bedreig”.

Amerikaanse wetenskaplikes hou reeds jare lank die supervulkaan onder die Yellowstone-nasionale park in die VSA dop. ‘n Supervulkaan is honderd keer so kragtig soos ‘n gewone vulkaan en kan nie net miljoene mense laat omkom nie, maar ook ‘n hele beskawing uitdelg. Indien Yellowstone sou uitbars, sou die hele Noord-Amerika verwoes word en die aarde mag enkele jare lank in ‘n “vulkaniese winter” gedompel word.

Die laaste bekende supervulkaniese uitbarsting het blykbaar ongeveer 70 000 jaar gelede plaasgevind langs die Toba-meer in Soematra, Indonesië. Dit het ‘n vulkaniese winter veroorsaak wat ses tot agt jaar geduur het, asook ‘n tydvak van aardverkoeling ingelui wat ‘n duisend jaar geduur het.

‘n Onlangse wetenskaplike ontleding van die gesmelte rots onder die Yellowstone-nasionale park in die Verenigde State van Amerika het onthul dat ‘n uitbarsting sonder enige eksterne invloed moontlik is.

Wetenskaplikes het voorheen geglo dat vele supervulkaniese uitbarstings eers deur ‘n aardbewing ontketen moet word om die aarde se kors oop te breek vir die magma om te ontsnap. Maar nuwe navorsing toon dat dit spontaan as gevolg van ‘n toename in druk kan plaasvind.

Supervulkane verteenwoordig die tweede grootste gevaar vir lewe op aarde, ná ‘n botsing van die aarde met asteroīdes, en hulle was in die verlede verantwoordelik vir massa-uitsterwings van spesies op aarde, langtermynklimaatsveranderings en korter “vulkaniese winters” wat veroorsaak word as vulkaniese as die sonlig afkeer.

Amerikaanse wetenskaplikes het Suid-Afrika geīdentifiseer as ‘n gebied waar mense sou kon oorleef tydens die vulkaniese winter wat Yellowstone sou veroorsaak. Hoewel die Amerikaanse regering geensins paniek onder sy burgers wil veroorsaak nie, is op ‘n “gebeurlikheidsplan” besluit indien die ergste wel sou plaasvind en Yellowstone tot uitbarsting kom.

Die vulkaan word tans deurentyd deur seismograwe by 45 punte gemonitor en waarskynlike sou die VSA oor enkele weke of dae se waarskuwing beskik om groot getalle van sy burgers oorsee en veral na die suidelike halfrond te stuur.
Kunstenaarsvoorstelling van Yellowstone wat uitbars

Yellowstone in die deelstaat Wyoming het 600 000 jare gelede ‘n uitbarsting beleef en meer as 1000 kubieke kilometer as en lawa in die atmosfeer ingestuur – omtrent 100 keer meer as die Berg Pinatubo-uitbarsting in die Filipyne in 1982, wat ‘n merkbare tydvak van globale verkoeling meegebring het.

Hoewel die Suid-Afrikaanse ministeries van buitelandse sake, asook wetenskap en tegnologie, volledig oor die Amerikaanse plan ingelig is, tesame met die groot bedrae geld wat betaal sou word om tydelike huisvesting vir Amerikaners in die Karoo en in die Kalahari op te rig waar hulle sou kon oorleef, het die kabinet besluit om die Amerikaanse versoek van die hand te wys.

Die R100 miljard sou van 2014 af elke jaar vir tien jaar aan Suid-Afrika betaal word, waarna die plan hersien sou word.

Dit kan tot tien jaar neem vir druk om in die magmakamer van die supervulkaan op te bou. Volgens dr. Jean-Philippe Perrillat van die Nasionale Sentrum vir Wetenskaplike Navorsing in Grenoble, Frankryk, “is dit die verskil in digtheid tussen die gesmelte magma in die kaldera en die omliggende rots wat groot genoeg is om die magma vanuit die kamer na die oppervlak te laat styg”.

“Die uitwerking is dieselfde as die ekstra dryfvermoë van ‘n sokkerbal wat onderwater met lug gevul word, waarna dit na die oppervlak styg omdat die omringende water digter is,” sę dr. Perrillat. “As die volume magma groot genoeg is, behoort dit na die oppervlak te styg en te ontplof soos ‘n sjampanjebottel wat ontkurk word.”

Volgens dr. Sipho Mathetwe, het die Suid-Afrikaanse regering “simpatie vir die Amerikaanse uitdaging (challenge) met Yellowstone, maar ons het ons eie uitdagings in Suid-Afrika. Daar is 200 miljoen witmense in Amerika en as te veel van hulle Suid-Afrika toe vlug, kan dit ‘n groot probleem veroorsaak, selfs al is daar genoeg huisvesting en infrastruktuur beskikbaar. Dit sal die land destabiliseer en kan selfs apartheid laat terugkom. Suid-Afrika is nie te koop nie.”

Die Amerikaanse ambassadeur in Pretoria was nie vir kommentaar beskikbaar nie.

Oeh weer recente Yellowstone updates.

Dat de situatie dreigender lijkt te worden, wil niet zeggen dat het in het verleden (voor de eerste metingen) er al eerder zo uitgezien heeft. Die tientallen jaren dat de vulkaan in de gaten gehouden wordt, verbleekt natuurlijk tegen die ruim 600.000 jaar dat er niets gebeurd is. Of misschien zijn er in de tussentijd wel kleinschalige dingen gebeurd in Yellowstone park, maar zijn er geen waarnemingen van vastgelegd en is er niets van terug te vinden in de bodem. Sowieso liep er in een groot deel van die periode nog geen mens op het Amerikaanse continent.

How to keep things hot at Yellowstone and Katla: Just add water
Two volcanoes that get the interwebs all hot and bothered have made the news in the last week. First, Katla in Iceland produced some glacial flooding (jökulhlaups) that followed some earthquakes. Second, over at everyone’s favorite caldera, Yellowstone, there has been a lot of buzz over roads melting due to heat from the volcano. Now, as odd as it might seem, these two events are connected by the same process: geothermal (and hydrothermal) activity. When it comes down to it, most volcanoes are sitting on big heat sources. One way to lose the heat is by erupting, but probably the most important way to lose the heat is by the circulation of water in the crust. This water help keep things hot by efficiently moving heat generated by the magma that might be 5-6 kilometers (or more) below the surface and bringing it up to the surface — all of this happening when there is no threat of an eruption.

When you examine the history of a volcano, you’ll quickly see it spends much of its existence not erupting. However, during those periods of quiet between eruptions, there is plenty going on beneath the volcano. The magma is cooling and releasing heat and fluids in the surrounding rocks, causing the development of a hydrothermal system above the cooling magma. This is usually the top 5 kilometers of crust above the magma, where cracks in the rocks can help hot fluids rise from the magma and cool fluids (like rainwater or snowmelt) percolate down into the crust and heat up. So, how hot does it get under a volcano? Well, by examining the exposed innards of extinct volcanoes, we can see how much alteration the rocks and minerals have experienced. This is an important step in understand how certain valuable ore deposits, like porphyry copper, form above bodies of magma under volcanoes.

Looking at these zones of hydrothermal alteration, it is clear that the subsurface temperatures get hot — upwards of 300-500°C even multiple kilometers above any cooling magma body. Now, that heat isn’t getting there by conduction alone. Rock isn’t a very good conductor, so heat won’t travel far. However, if you heat up water traveling through cracks in the rock, you can transport a lot of heat upwards. That’s because water has a high heat capacity – think about how the Gulf Stream brings warm water from the tropics to the North Atlantic to keep Europe warm. That is what allows all the alteration to occur and for hydrothermal systems to form. These hydrothermal systems are constantly changing based on the seasons (thanks to changing access to water percolating into the crust), seismicity that opens and closes cracks and yes, even magma moving. However, most of the time, the changes in the system are merely due to new routes these hot fluids take to reach the surface.

What are the manifestations of these hydrothermal fluids? You see some of them at most active volcanoes: steam vents (fumaroles), hot springs, geysers, mud pots. Each is a different way heat escapes the ground. Steam vents tend to be the hottest, releasing steam (with other volcanic gases) at temperatures of 300-500°C. Geysers are explosions of superheated water, so they will be ~100°C. Hot springs and mud pots tend to be much cooler, with temperatures usually 20-70°C, depending of the vigor of the spring or geyser.

So, even moving water through the crust can bring a lot of heat upwards and that is common at most volcanoes — as are changes in the hydrothermal system over time. So, what is happening at Katla and Yellowstone?First, at Katla, the hydrothermal system works underneath a large ice cap (Mũrdalsjökull). Especially during warmer months, more water can percolate into the crust, causing changes in the hydrothermal system (which, by itself, can generate earthquakes). If more heated water and steam is allowed to reach the surface, then more ice can melt and pond until it is catastrophically released as a flood. Reports from the Iceland Met Office support this idea – the waters are warm as they come out from under the glacier. However, unlike an eruption-driven event, the melting isn’t accompanied by a continuously increasing number of earthquakes that would betray magma moving. So, the most likely explanation for these floods is increasing melting due to changes in the hydrothermal (geothermal) system, not an eruption. These sorts of floods have happened before during this time of year at Katla, sometimes more dramatic than others.

Now, at Yellowstone, we have a different manifestation of the same thing. The news has splashed images of melting roads on Firehole Lake Drive in an area with intense hydrothermal activity. The usual suspects (e.g., the Yellowstone disaster groupies) want to say this is evidence that an eruption is in the works. Well, again, sorry to disappoint the lunatic fringe, but it isn’t. Instead, this is a sign that the hydrothermal system under Firehole Lake Drive has shifted some — maybe due to the constant seismicity that gently shakes Yellowstone, maybe due to the water table, maybe even due to the road itself — and now heat is coming up directly under the road. Now, asphalt like that can melt at temperatures as low at ~50-70°C, so well within the range of most hydrothermal features. Measures of the road surface by NPS workers are ~70°C, so we’re well within the range of temperatures needed to melt the road. Just move where that hot spring or fumarole is coming up and boom, you have heat under the road, melting it.

Breaking: Yellowstone Geëvacueerd: Experts beweren dat ‘Super Vulkaan’ binnen enkele weken kan uitbarsten!

15509350082583454212

Yellowstone National Park is haastig geëvacueerd uit angst voor een uitbarsting van de supervulkaan Yellowstone Caldera. Deze uitbarsting wordt geacht veel sneller dan eerder werd verwacht te naderen. Onderzoekers op dit terrein beweren dat de 640.000 jaar oude supervulkaan een plotselinge piek van activiteit aangeeft waaruit kan worden afgeleid dat deze zou kunnen gaan uitbarsten in slechts twee weken. Een explosie veroorzaakt door de vulkaan vrijwel de gehele Verenigde Staten in een 200 jaar lange vulkanische winter, storten en met as het zonlicht uitwissen . Hierdoor zou de pyroclastische STROOM onherstelbaar beschadigd raken evenals het omringende ecosysteem.

timthumb-2.jpg

Twee weken geleden werden een aantal wegen gesloten nadat het asfalt begon te smelten en er scheuren ontstonden vanwege de extreme temperaturen onder het aardoppervlak. Niemand heeft nog kunnen lokaliseren wat deze plotselinge stijging heeft veroorzaakt. Experts houden toezicht op de vulkaan en zijn vooral bezig met het weghouden nieuwsgierigen uit het park, evenals het VEILIG ontruimen en evacueren van omliggende gebieden om eventuele ongevallen te voorkomen.

De wetenschappelijke gemeenschap is verdeeld over wanneer de vulkaan precies zal uitbarsten. Sommigen zeggen weken, terwijl andere kampen suggereren dat het een kwestie van maanden zou kunnen zijn. Over een ding zijn ze het echter allemaal eens, en dat is dat het zeer, zeer binnenkort zal gebeuren. Senior Vulkanoloog Richard Dunn gaf het volgende verslag met betrekking tot de alarmerende activiteit van de vulkaan. “Dit is iets wat nog nooit eerder is gebeurd. Deze onvoorspelbare flux van de activiteit is zeer zorgwekkend, en gaat lijnrecht in tegen al onze eerdere studies met betrekking tot deze bijzondere vulkaan. Onze voornaamste zorg op dit moment is om mensen in veiligheid te brengen. ”

Is The Yellowstone Supervolcano About To Erupt?

2796298152_e408c7a97c_o.jpg

The internet is both a blessing and a curse. It provides us with endless information on any topic you could dream of at just the click of a button. On the flip side, it’s full of crap that’s easy to believe if you don’t spend the time looking for credible sources to back up what is being said. One such example is the Yellowstone supervolcano. Rumors often surface that it is about to erupt, and they’re doing the rounds once again. So, what’s the crack with this colossal caldera? Is it about to shoot its load and wipe out millions of people? Let’s take a look.

Yellowstone National Park is home to a huge caldera (bowl-shaped feature that resulted from the collapse of land after a volcanic eruption) and supervolcano that are collectively known as the Yellowstone Caldera. A recent study discovered that the volcano has a gargantuan magma chamber measuring 90 km in length and up to 17 km in depth in some areas, which was more than double previous estimates. However, according to experts, the updated size does not increase the volcanic hazard in the Yellowstone region.

Scientists believe that three super-eruptions have occurred in the past on a 600,000-700,000 year cycle, starting around 2.1 million years ago. The last huge eruption is thought to have occurred around 640,000 years ago, but that doesn’t necessarily mean we’re in the firing line right now. At the same time, scientists are very aware of the implications of such an eruption. Consequently, the US Geological Survey (USGS) Volcanic Hazards Program keeps a watchful eye on this beast and is constantly recording its activity via seismometers and other bits of monitoring equipment.

It is not a quiet volcano- hot fluids are constantly yo-yoing through the crust, resulting in frequent earthquakes. Indeed, just last month 99 earthquakes were recorded by the USGS in the Yellowstone National Park region, the largest of which was a magnitude 2.5. Furthermore, 50% of these occurred in just two consecutive days. This may sound like a lot, but it’s common for this region and the activity was not outside of normal background levels. If an eruption was on its way, hundreds or even thousands of earthquakes would be triggered as the magma forces its way through the crust. It wouldn’t go unnoticed, so until the USGS tell us that this is happening, you can be fairly certain that rumors of an imminent blow are just that-rumors, nothing more.

Scientists also believe that if an eruption were to take place in the not-so-distant future, it would probably be (relatively) small, maybe on a Mount St Helens scale, rather than a super eruption that is going to wipe out large numbers of people.

A few months back, many people got their knickers in a twist about a video supposedly showing bison fleeing the park. Some believed that this meant that the volcano was about to blow because it coincided with a magnitude 4.7 earthquake, but that was not the case. The animals leave the park during winter to migrate to lower elevations where food resources are more likely to be abundant. Furthermore, the video was recorded some weeks before the big quake.

In sum- experts are watching this supervolcano like a hawk and they produce monthly updates on it for us all to see. If something out of the ordinary was going on, the USGS would tell us. If eruption warnings or scares start floating around the internet, check the source, because if it’s not from the USGS or another credible organization then it’s probably not true.

Yellowstone Supervolcano Eruption Would Doom the United States

Melted roads, the strongest earthquake in more than 30 years, spiking gas emissions from hot springs, animals purportedly "fleeing" the park's boundaries — all those events must be signs that the supervolcano lying dormant beneath Yellowstone National Park is poised for the first eruption in 70,000 years, right?

Wrong. As the head of the U.S. Geological Survey's (USGS) Yellowstone Volcano Observatory, Jacob B. Lowenstern, told The Billings Gazette, there's no "abnormal" activity going on beneath Yellowstone.

"The probability of a large … eruption within the next few thousand years is exceedingly low," a USGS report concludes.

But say the supervolcano were to erupt today, what sort of impacts would the United States experience? Thanks to new research from the USGS we finally have some answers, and the findings are decidedly grim.

According to the report, a major eruption at Yellowstone's supervolcano would send a plume of ash with a volume roughly 850 times greater than that of the one observed during the eruption of Mount St. Helens into the atmosphere. Areas just outside ground zero of the supervolcano could see more than 3 feet of ash, which would kill crops, electronic communication and travel to and from the areas. Even New York City, more than 1,500 miles away, would see ash from the Yellowstone eruption, albeit in lesser amounts.

As Discovery notes, such a large quantity of ash could also cause global temperatures to plummet. Weather patterns could also shift in an order of magnitude far greater than that of the Tambora eruption of 1815, one of the most devastating volcanic eruptions in recorded history. As Slate notes, the eruption of Tambora brought drought, disease and an unending winter to much of the globe. On the East Coast of the United States, for instance, the eruption triggered major snowstorms as late as June.

However, the most significant finding from the study is that ash plumes from larger volcanic eruptions don't follow the same rules as eruptions of a lesser magnitude. Ash plumes from smaller eruptions don't shoot as high up into the atmosphere as ash from larger eruptions, meaning the ash gets caught up in the jet stream and carried off in a set direction along with it.

But an eruption of the magnitude of Yellowstone's would shoot ash miles above Earth, well into the stratosphere, avoiding the jet stream and creating an "umbrella" of ash that would blanket the United States in a widespread, but relatively even pattern, The Billings-Gazette notes.

“In essence, the eruption makes its own winds that can overcome the prevailing westerlies, which normally dominate weather patterns in the United States,” USGS scientist Larry Mastin told Raw Story. “This helps explain the distribution from large Yellowstone eruptions of the past, where considerable amounts of ash reached the West Coast.”

Ash deposits as thick as 6 feet were detected in the geological record in areas of the Midwest, the USGS reports, partial byproducts of the three most recent major eruptions of the Yellowstone supervolcano, which took place 640,000, 1.3 million and 2.1 million years ago.

Yellowstone Volcano: 98 Earthquakes Revealed In Latest Report By USGS

In the latest update of the Yellowstone volcano by the United States Geological Survey (USGS), October registered 98 total earthquakes in the Yellowstone National Park region. This seismic activity shows 21 more earthquakes than those reported in September. Although there was more activity in October, the highest magnitude was lower than the one reported in September.

The volcano’s current alert level is “normal” and current aviation color code is “green.” This is indicates that no massive eruption of the supervolcano is imminent.

According to the USGS, their information comes the University of Utah Seismograph Stations and is responsible for the operation and analysis of the Yellowstone Seismic Network.

“During October 2014, the University of Utah Seismograph Stations, responsible for the operation and analysis of the Yellowstone Seismic Network, reports 98 earthquakes were located in the Yellowstone National Park (YNP) region. The largest event was a small earthquake of magnitude 2.7 on October 29, at 3:55 PM MDT, located about 17.5 km (11 miles) south-southwest of West Thumb, YNP. This earthquake is part of a small swarm of 15 earthquakes that occurred over six hours.

“Yellowstone earthquake activity in October is at low background levels.”


As the Inquisitr reported for September, nearly half the earthquakes were registered for the Yellowstone volcano in September than there was in August. August had 207 and 71 were reported in September. The strongest earthquake that month was September 24 when it reached a magnitude of 3.2 about 9 miles south of Mammoth.; no earthquake swarms were reported in September.

Ground deformations were updated by the USGS as well in the October report.

“Ground deformation was also reported in north-central Yellowstone. The rate of subsidence is holding steady at about 5 centimeters a year.

“The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.”


The National Park Service posted a notice on its website that Yellowstone volcano won’t erupt anytime soon despite rumors implying otherwise.

“Though another caldera-forming eruption is theoretically possible, it is very unlikely to occur in the next thousand or even 10,000 years.

“The most likely activity would be lava flows such as those that occurred after the last major eruption. Such a lava flow would ooze slowly over months and years, allowing plenty of time for park managers to evaluate the situation and protect people. No scientific evidence indicates such a lava flow will occur soon.”

Tering hé, als dan zo 'n supervulkaan ontploft zoals die van de Yellowstone Park, hoeveel energie in megaton komt er dan wel niet vrij? :P
De vulkaanuitbarsting van de Krakatau en de Tambora hadden iig een kracht van 200 megaton.

Een paar gigaton volgens mij. Maar het grote probleem gaat niet de energie zijn maar de enorme hoeveelheid as en stof die vrijkomt (meer dan 1.000 km3). Genoeg om hele VS onder een laag as van enkele centimeters te bedelven en een kleine ijstijd op Aarde te veroorzaken.

Ik maak me eerlijk gezegd meer zorgen om de vulkanen op IJsland.
