Researchers found that magma chambers beneath Cascade Range volcanoes persist even when the volcanoes are dormant, challenging previous assumptions. This discovery could improve volcanic monitoring and eruption prediction.
New research led by Cornell University challenges the long-standing belief that active volcanoes contain large magma bodies that are expelled during eruptions and gradually dissipate as the volcanoes become dormant.
Using seismic waves, researchers identified magma chambers beneath six volcanoes of varying sizes and dormancy within the Cascade Range, which includes half of the U.S. volcanoes designated as “very high threat” by the U.S. Geological Survey. The team discovered that all of the volcanoes, including dormant ones, contain persistent and sizable magma bodies.
The study, led by postdoctoral researcher Guanning Pang, was published in Nature Geoscience and co-authored by Geoffrey Abers, professor in geological sciences.
Their results are surprising given that some of these volcanoes, such as the Crater Lake volcano in Oregon, have not been active in millennia.
Magma Bodies Exist Throughout a Volcano’s Lifetime
“Regardless of eruption frequency, we see large magma bodies beneath many volcanoes,” Pang said. “It appears that these magma bodies exist beneath volcanoes over their whole lifetime, not just during an active state.”
The fact that more volcanoes have sustained magma bodies is an important consideration for how researchers may monitor and predict future volcanic activity. The U.S. Geological Survey has been expanding and upgrading its volcanic monitoring networks in the Cascade Range and elsewhere as part of the National Volcano Early Warning System, with the aim of detecting signals of an impending eruption as early as possible.
“We used to think that if we found a large amount of magma, that meant increased likelihood of eruption,” Pang said, “but now we are shifting perception that this is the baseline situation.”
The results suggest that an eruption does not completely drain a magma chamber, instead, it lets off some of the excess volume and pressure. The chamber can be slowly expanded and refilled over time due to gradual melting of the crust.
“If we had a better general understanding of where magma was, we could do a much better job of targeting and optimizing monitoring,” Abers said, noting that there are a “great many volcanoes that are sparsely monitored or have not been subject to intensive study.”
Plans are already in the works to expand the magma monitoring system and see if the Cascade discovery translates to other locations, including Alaska.

Nuclear testing from country s could cause a reaction, that would lead to the destruction of the world.
Your remark is a little terse to be sure exactly what you mean. Could you be more specific what kind of a “reaction” you mean? Just how do you propose that any kind “reaction” could destroy the world?
If as what was said about volcanoes is now better understood. That at one time certain volcanoes were that to be extinct but scientists have found but some of the ones they thought were extinct are coming back to life well if that is so and according to what I just read that there’s a lot of water and the volcano that makes it worse when it comes to exploding well I don’t know about the rest of the volcanoes in the world but here in the Pacific Northwest we have a caldera that’s was one of the biggest in the world at one time called Mount mazama it exploded over 6,000 years ago and since has formed what they call Crater lake now that’s a lot of water in that volcano now they say they haven’t seen some signs in certain volcanoes about coming back to life but I remember that there is a little Island in the now Big lake there and it’s called wizard Island and it has smoked coming out of it or seeing whatever you want to call it so it is definitely still alive what is the possibility of this volcano erupting again violently like it did over 6,000 years ago that is one of my questions and another of my question is here in Portland Oregon we have a small volcano at one time according to what I’ve always been told is that this little volcano burn itself out but if these Chambers fly deep below a volcano is considered to be extinct then what is the possibility of this little volcano becoming active again it sits real close to downtown Portland it’s called Mount Tabor Park and have the volcanologist also been checking to see if there’s any magma Chambers below that Park or has it been monitored that’s just a few of my questions I know the first volcanoes also in different parts of Africa also known to be extinct as any of those shown signed I’m coming back to life as well
Not surprised, this big old rock has never been “sleeping”
Seems pretty intuitive that this would be the case. I understand they had to prove it but I don’t get why they were surprised?
They were surprised because it is counter to the accepted paradigm.
The following may prove phase transitioning dark matter happens in the Earth.
Don’t misunderstand this is a natural process that may give us a temperature control for our 3 habitable zone planets. When I was in university consensus was temperature rose first historically. Dark matter is the chicken and CO2 is the egg. This effect can be seen hundreds of miles off of the path of totality.
The barycenter between the moon and the earth lies approximately 1400km below the surface of the Earth, this is where I believe the dark matter phase transitions and releases heat. The data I pulled was at random as a trial.
I have run the data for 14 cities during solar eclipses so far:
One was on the coast and I believe the water may have damped the data.
One it rained for a week after the eclipse which may have also damped the data.
Nine of these had about a 3deg F bump above the average temperature 6 days later.
Eight of these contained the hottest temperature of the month.
The bump in temperature will usually last for about 3 days.
After pulling more data for eclipses around the world I was surprised to see that even the majority of areas exposed to partial eclipses showed temperature spikes 6-8 days later. The North American data (Mexico city to Ontario)for April 2024 shows the same thing.
We know it is there from the effects we can see that tell us the most likely cause. If you look at the effects and logic the most likely cause you get dark matter.
Physicists may come up with a better reason. We are still at the stage of collecting enough data to verify that it is valid.
When my wife first suggested that dark matter might be causing global warming I laughed . Dark matter after all should be a constant, I thought. When we began looking at the data I stopped laughing. Dark matter it seems is not a constant.
Planetary heating is increasing but dark matter is the chicken and Co2 is the egg.
Dark matter phase transitions appear to be a primary internal heater of the planets. If the solar system passes through an area of higher liquid dark matter content the planets cores would all receive more heat due to increased phase transitions thus heating the earth from the inside out. That means if we redirect part of the dark matter circulation of Venus or Earth to Mars we could warm it up. Mars also passes through streams of dark matter headed to every planet capturing slightly more of these would also help. These streams may be more like intermittent clouds going by on a windy day by the time they reach Mars orbit. Redirecting dark matter could warm Mars.
Heating of the planet from the inside out would result in :
Increased ground temperatures
Increased sea temperatures
Increased nighttime temperatures
Increased volcanic activity – Mars lava plumes 09/24
Increased earthquakes – Mars 4.2 earthquake 07/21, 4.7 quake 05/22
We are currently passing through the S1 dark Matter stream which, as it is going the opposite direction around the galaxy was described as a dark matter hurricane. From spring to fall the earth is downstream from the sun. And from July to December the earth is traveling with the S1 stream and from January to June we get our maximum ongoing dark matter exposure as we travel into the S1stream. It would be interesting to see if the upper atmosphere temperatures are lower in the spring than the fall due to more incoming dark matter. There have also been peer reviewed papers that discuss dark matter annihilation(or in my hypothesis phase transition)heating the earth from the inside, they did not mention any impact to climate change or the S1 dark matter stream.
We may also be subject to surges of dark matter which mean heat at the surface and cool in the upper atmosphere just before.
Feb 25 1980 the earth crossed the path of Mars and Jupiter. March 1-2 the temperature spiked. I do not know where the moon shadow was during that period.
March 27 eruptions began May 18 was the main eruption.
June-July 2020 Earth Mercury Venus Mars Jupiter Saturn conjunctions. This means that the earth passed through several consecutive dark matter streams
July 2020 Siberian heatwave and Antarctica temperature spike
Jan 9 2022 Venus Earth conjunction this resulted in an increase in the amount of dark matter leaving the sun and Venus
March 18 2022 Concordia Station spiked 39 C degrees due to unusual air patterns near Australia
North Pole regions hit 30C above normal
May 2022 mars crosses the dark matter stream to Saturn
May 4, 2022 a 4.7 magnitude Marsquake occurs due to tectonic activity.
March 26 2024 the Parker Solar Probe began its lap around the sun on April 4 it came out on the other side of the sun to start back towards Venus. In between it was actually inside of the Alfven Limit which is where I believe the surface of the dark matter sphere that surrounds the sun lies. This would be the equivalent of a speed boat sending a wake towards the earth.
April 11 mercury and earth are in an inferior conjunction which would also send a bit of extra dark matter in earths direction.
Mid June 2024 multiple heat waves.
Venus atmospheric temperatures from 2009-2017 also were higher after conjunctions and the atmospheric wind speeds have increased by 33% probably due to the increase in incoming dark matter.
Venus atmospheric temperatures from 2009-2017 also were higher after conjunctions
Venus atmospheric tsunami
If the dark matter spin off to the sun happens every 5 days on average and coincides with the wave facing the sun it may be proof of dark matter. During conjunctions if the tsunami is facing earth we get an extra surge of dark matter heading to the earth which also affects the time it takes for the tsunami to circle Venus. The gravity well fills up and dumps back to the sun but if it fills faster due to a conjunction it can spill toward the earth resulting in higher temperatures about 60 days later. The streams of liquid dark matter are constantly overflowing the suns dark matter sphere which extends to the Alfven radius. This distance varies dependant on how much dark matter reaches the point at which it vaporizes. (Velocity/gravity/temperature)
NASA issued a climate change warning for Mars after Mariner 9
Neptune has been heating up since2018
“The streams of liquid dark matter are constantly overflowing the suns dark matter sphere which extends to the Alfven radius.”
This sound like a line out of one of the ‘Lord of the Rings’ fiction books.
Astronomers aren’t even sure that Dark Matter exists. Some consider “Dark Matter” to be a euphemism for something that causes otherwise unexplained astronomical effects.
And here you are giving names, such as “S1 dark Matter stream,” and proposing phase changes in something, where, absent significant gravity, there are only ionized and unionized particles, more like a plasma or gas than a liquid or solid.
“If the dark matter spin off to the sun happens every 5 days on average and coincides with the wave facing the sun it may be proof of dark matter.”
That is like saying “If the the unicorn dances on its hind legs for 5 days it may be proof of unicorns.” What have you been smoking? Kamala could take some word salad lessons from you. Tell me, “Why is a mouse?”
I’d suggest that you spend your time proving that Dark Matter even exists before you start telling us about all of its unusual magical properties.
