Yellowstone ALERT: 200 Earthquakes In 10 Days As Ring Of Fire Awakens


Scientists in Yellowstone have detected over 200 earthquakes at the supervolcano in the last 10 days. With reports coming in that the Ring of Fire could be awakening as well, many are preparing for the worst.


Although scientists are still telling the public there’s no need to be alarmed, reports of immense pressure in the magma chamber under Yellowstone, coupled with this new report claiming 200 earthquakes have been recorded in the last ten days are reigniting fears of a potential supervolcano eruption. According to The Daily Mail, this latest earthquake swarm began on February 8.


Experts with the US Geological Survey say that this latest swarm began in a region roughly eight miles northeast of West Yellowstone, Montana and, it’s increased dramatically in the days since. While the earthquakes are likely caused by a combination of processes beneath the surface, the current activity is said to be “relatively weak,” and the alert level at the supervolcano remains at “normal.” The USGS says the new swarm is occurring in about the same location as the Maple Creek swarm last summer, which brought roughly 2,400 earthquakes in a four-month span.


Experts also say there are likely many more earthquakes in the Yellowstone region that have gone undetected.  “The present swarm started on February 8, with a few events occurring per day,” according to USGS. “On February 15, seismicity rates and magnitudes increased markedly. As of the night of February 18, the largest earthquake in the swarm is M2.9, and none of the events have been felt. All are occurring about 8 km (5 mi) beneath the surface.”


“Swarms reflect changes in stress along small faults beneath the surface, and generally are caused by two processes: large-scale tectonic forces, and pressure changes beneath the surface due to accumulation and/or withdrawal of fluids (magma, water, and/or gas),” USGS explains. “The area of the current swarm is subject to both processes.”


“While it may seem worrisome, the current seismicity is relatively weak and actually represents an opportunity to learn more about Yellowstone,” USGS says. “It is during periods of change when scientists can develop, test, and refine their models of how the Yellowstone volcanic system works.” However, the experts did lace a warning into their statement. “The earthquakes, too, serve as a reminder of an underappreciated hazard at Yellowstone – that of strong earthquakes, which are the most likely event to cause damage in the region on the timescales of human lives.”

Apocalyptic Super Volcano Eruption Could Be Much Closer Than Previously Thought

super-volcano


A lot of geology news has circled around the possibility of a supervolcano eruption that could wipe out humanity.  And a new analysis is not very comforting, as scientists discover that the apocalyptic scenario may be much closer than they previously thought.


The largest super-eruptions are capable of covering entire continents in volcanic ash and changing weather patterns around the world for decades. And a new study suggests the next eruption of this magnitude could be sooner than was previously assumed.


Regular volcanic eruptions, such as the recent activity of Mount Agung in Bali, might be enough to close airports, but a super-eruption would have the potential to destroy human civilization as we know it. Like Mount Agung, one of the last known super eruptions also took place in Indonesia.



Scientists previously estimated that super-eruptions happen every 45,000-714,000 years, a length of time Professor Jonathan Rougier, statistician and lead author of the new study, describes as “comfortably longer than our civilization”. (Civilization is often dated to the time humans moved away from hunting and gathering and towards agriculture, around 12,000 years ago.) In the new Earth and Planetary Science Letters study by Professor Rougier and his team at the University of Bristol, they used a database of geological records to produce a new estimate of between 5,200 and 48,000 years, with a “best guess value” of 17,000 years.  Although still a while from now, it could be much sooner than the 45,000 years conservative estimate from before.


“On balance, we have been slightly lucky not to experience any super-eruptions since then,” said Professor Rougier.  He also took care to note that just because it’s already been roughly 20,000-30,000 years since the most recent super-eruption, doesn’t mean the next one is “right around the corner.”


“Nature is not that regular,” he said. “What we can say is that volcanoes are more threatening to our civilization than previously thought,” said Professor Rougier.

‘UFO’ Sighted Zig-Zagging Over Yellowstone Supervolcano


yellowstone-lake-adapt-945-1


A new video has surfaced on YouTube which shows what appears to be a UFO zig-zagging it’s way over the Yellowstone supervolcano in northern Wyoming. The video was taken on June 9, but only recently uploaded to the video-sharing site.


The bright metallic object can be seen zipping across the sky on the left.



Yellowstone has long been a hotspot for alien sightings and UFO enthusiasts. According to the National UFO Reporting Center, there have been hundreds of reported sightings in the state of Wyoming, going all the way back to 1871. Jeanetta Foresta uploaded a video of the sighting under the heading “Things R flying all over – overnight”. She posted: “There were more than four at the beginning and this is overnight so there is no sun to reflect off of a plane.”

A still image from the video of the UFO.


This is not the first sighting of an unidentifiable object in the sky near Yellow Stone. In 2016 there too was a sighting of what appeared to be a drone-like object hovering directly above the head of the summit. Footage of this sighting can also be found on Jeanette’s channel under a video titled “Things Are Flying All Over The Night Sky! Upper Basin – Overnight!”


The famed Yellowstone volcano has garnered national interest in recent months, especially over the summer when more than 400 earthquakes hit in one week near the volcano. “This is the highest number of earthquakes at Yellowstone within a single week in the past five years, but is fewer than weekly counts during similar earthquakes swarms in 2002, 2004, 2008 and 2010,” scientists explained in a June statement to the Star Valley Independent. The scientists added, however, that the swarms are nothing new and are not a cause for worry. Experts at the U.S. Geological Survey (USGS) say the risk of the Yellowstone supervolcano erupting is quite low, with a probability of one in 730,000.


There is still no official explanation for what was captured on this video.

No Tsunami Warning Issued After Major Earthquake Off Japan’s Coast


tsunami


The Fukushima nuclear power plant in Japan could have been facing a possible tsunami after a 6.1 magnitude earthquake rolled just off the coast of Japan. This quake is just one more to add to the increasing tectonic activity on earth lately, yet experts do not believe that this one will cause a tsunami.


Just after the massive 7.1 earthquake in Mexico city, several other large quakes occurred around the globe and a volcano erupted. The volcano’s eruption was triggered by the earthquake in Mexico,  but the quake just off the coast of Japan is striking fear into those near the nuclear power plant over a tsunami. The earthquake struck less than 24 hours after a horrific quake rocked Mexico City and left hundreds dead.


According to Fortune, there have not been any reports of damage or tsunami warnings, but the story is still developing. The U.S. Geological Survey (USGS) reported the seismic event, but so far the National Oceanic and Atmospheric Administration (NOAA) has yet to comment on possible tsunami activity, however, the government agency is currently monitoring Hurricane Maria off the coast of Puerto Rico.



Japan is understandably on edge over undersea earthquakes, after 2011’s 9.0-magnitude event caused massive damage at the Fukushima Daiichi Nuclear Power Plant. Ultimately nearly 20,000 people were killed or went missing during that earthquake, which was the fourth-largest in world since measurements began in 1900. The earthquake, and subsequent tsunami waves (which were up to 130 feet high), caused $220 billion in damage to Japan. The waves hit the Fukushima Daiichi plant so hard that the nuclear facility began to melt down. The nearby town was ordered to evacuate amidst the fallout, and more than 5,000 aftershocks hit over the next year—including one that measured 7.9 on the Richter Scale. – Fortune




The nuclear power plant suffered radiation as a result of the2011 tsunami sparked by the quake and triggered a 30km evacuation zone. Because the leaks continue to this day, there is now a 20km no-go area which may only be entered under government supervision. This was the most significant nuclear incident since the Chernobyl disaster, in 1986.


The swarm of earthquakes across the globe is raising fears over a super volcano eruption, or an even larger quake that could devastate the entire west coast. Even though there was no tsunami warning issued after this recent earthquake off of Japan’s coast, those in the nation are rightly concerned. But again, experts do believe that this recent earthquake does not pose a tsunami threat.

Over 250 Earthquakes In Idaho In 9 Days Leads To More Super Volcano Fears


sodasprings


An earthquake swarm in south eastern Idaho is rattling windows across parts of the state and Wyoming and Utah.  There have now been over 260 earthquakes since September 2, in the Soda Springs area and many have been over a magnitude of four or even higher on the scale.



The earthquake swarm in Southeast Idaho looked like it might be ending or at least slowing down on Thursday and Friday. But then Saturday arrived and by the day’s end, 19 quakes had struck. There have been 34 more temblors so far Sunday, bringing the earthquake total since the swarm began on Sept. 2 to 204 quakes. All of the quakes have occurred in the Caribou County area east, southeast and northeast of Soda Springs.


While many believe California and the West Coast are ripe for a huge earthquake, the heartland is often forgotten and these earthquakes are being swept under the rug and largely unimportant to the public at large.




While all eyes are on California’s San Andreas Fault because of the density of the human population there, many haven’t noticed Idaho’s swarm and the area which is highly active right now. Earthquake experts claim that the swarm in Idaho could end in a worst case scenario: a 7-magnitude quake that would reduce some buildings and homes to rubble and kill dozens or more – but the chances of that are incredibly small.




Dr. David Pearson, an Idaho State University geologist who studies earthquakes, said scientists who have researched some of the faults in Southeast Idaho have concluded that the 7.0 quake is possible at some point in the region’s future, but the current earthquake swarm is not necessarily an indication that it will occur anytime soon. Pearson said the faults in Southeast Idaho that produce earthquakes have not been extensively studied and this makes it difficult to determine when a destructive 7.0 earthquake could occur. –Idaho State Journal



The current earthquake swarm began on the night of Sept. 2 when 34 quakes occurred. Those were followed by another 34 quakes last Sunday, 28 on Monday, 20 on Tuesday, 25 on Wednesday, five on Thursday, five on Friday, 19 on Saturday and 34 so far Sunday. There was even a 4.5 magnitude quake in that area this morning, and people have reported feeling that quake as far away as Jackson, Wyoming.  All 260 plus of the quakes were reported by University of Utah Seismograph Stations.



Thus far, the most powerful temblor in the swarm was the second quake to occur. It was a 5.3 magnitude earthquake and struck at 5:56 p.m. September 2.




Authorities say it’s been years since Southeast Idaho experienced a quake of 5.0 magnitude or greater. Such quakes can cause damage to houses and other buildings, but fortunately, this was not the case. By comparison, a 7.0 magnitude quake would be at least 50 times bigger than the 5.3 magnitude temblor that hit Southeast Idaho last weekend.




The U.S. Geological Survey said that a 7.0 magnitude quake will inflict “considerable damage” to ordinary houses and buildings and will cause such structures to partially collapse. Such temblors will also cause chimneys, factory smoke stacks and walls to collapse, according to the USGA.


Of course, the swarm of earthquakes in Idaho isn’t limiting fears to a larger local quake.  Many are afraid that these swarms could trigger the Yellowstone super volcano’s eruption, as the caldera just northeast of the Soda Springs area, a mere 170 miles away. While it has been over 600,000 years since the last eruption, some seismologists are concerned the recent swarm of earthquakes may be sending warning signs the supervolcano is ready to explode once again.


“When a volcano starts ‘acting up’ prior to an eruption, one of the typical signs is increased seismicity,” research professor at University of Utah Jamie Farrell told Newsweek. Should the Yellowstone supervolcano erupt, thousands of people would die instantly from the explosion.


While an earthquake in Califonia could devastate the West Coast, a Yellowstone eruption has the potential to be a world wide extinction level event. Soda Springs, Idaho’s proximity to Yellowstone is hardly comforting.

Yellowstone Approaches Record Levels Of Seismic Activity


yellowstone-1400-0


By now, most are aware of the earthquake swarm under the Yellowstone super volcano.  Many people are fearing a major eruption, and those terrors aren’t calmed for some as the national park approaches a record number of earthquakes.


A cluster of earthquakes at the Yellowstone Park volcano is the most active it’s been in recent history. The earthquake count is up to 2,357 since June with the largest having a magnitude of  4.4. The majority of the earthquakes were magnitudes of 0 or 1, according to a report by Newsweek.


Yet scientists are assuring the public that a swarm of earthquakes doesn’t necessarily signal an eruption of the super volcano. But when the type of earthquakes occurring in Yellowstone deviates from the standard, it could mean that an eruption is forthcoming. A swarm of earthquakes is rather normal for Yellowstone, but the number of quakes is approaching a new record.


The current swarm is approaching the record set in 1985 when three months brought over 3,000 earthquakes. In 2010 a swarm brought over 2,000 earthquakes over a month.  Scientists still say to not worry too much. The threat of an eruption is still very slim.



The current situation doesn’t present too much of an eruption threat. The geological pressure would have to be sizable for anything to occur. “Yellowstone has had dozens of these sorts of earthquake swarms in the last 150 years it’s been visited. The last volcanic eruption within the caldera [crater] was 70,000 years ago. For magma to reach the surface, a new vent needs to be created, which requires a lot of intense geological activity,” said Jacob Lowenstern, one of the scientists managing the Yellowstone Volcano Observatory. –The Epoch Times



Lowenstern went on to say that the odds are very high that Yellowstone will go centuries more without an eruption and that if one does occur, it will be minor. Should these earthquakes lead to an eruption, scientists think it would not be of much consequence. “If Yellowstone erupts, it’s most likely to be a lava flow, as occurred in nearly all the 80 eruptions since the last ‘supereruption’ 640,000 years ago. A lava flow would be a big deal at Yellowstone, but would have very little regional or continental effect,” Lowenstern explained.

Uh Oh: Yellowstone Super Volcano Has Experienced 464 Earthquakes The Past Week

Uh Oh: Yellowstone Super Volcano Has Experienced 464 Earthquakes The Past Week

The Yellowstone super volcano has been hit by 464 earthquakes since June 12, according to the United States Geological Service’s (USGS) Yellowstone Volcano Observatory.


Some of the quakes were relatively high on the Richter scale. One, on June 15, was 4.5.


“The epicenter of the shock was located in Yellowstone National Park, eight miles north-northeast of the town of West Yellowstone, Montana,” a USGS statement said.

“[The 4.5] earthquake is part of an energetic sequence of earthquakes in the same area that began on June 12,” the statement continued. “This sequence has included approximately thirty earthquakes of magnitude 2 and larger and four earthquakes of magnitude 3 and larger.”


Seismic activity, such as earthquakes, can be a sign of an impending eruption.


The Yellowstone super volcano is actually a vast pool of partially molten rock or magma underneath the national park. Estimates are that it is 14,000 cubic miles in size, or 14 times the size of the Grand Canyon.


Scientists say that if it erupted, it would cover most of the continental United States and much of Canada and Mexico with ash; some places would be a meter deep. An eruption would be larger than the most powerful volcanic eruption in recorded history — that of Mount Tambora in Indonesia in 1815. It darkened skies throughout the world and ruined harvests as far as Europe. Many places in the Northeast experienced snow.


One fear of the super volcano is that it would cause a nationwide or worldwide famine by blacking out the sun and covering fields with ash.


The good news: Yellowstone also experienced similar earthquake swarms in 2002, 2004, 2008 and 2010. Scientists say the likelihood that the volcano will erupt this time is low.
