Explosive volcanic eruptions triggered by cosmic r

Abstract

Volcanoes with silica-rich and highly viscous magma tend to produce violent explosive eruptions that result in disasters in local communities and that strongly affect the global environment. We examined the timing of 11 eruptive events that produced silica-rich magma from four volcanoes in Japan (Mt. Fuji, Mt. Usu, Myojin-sho, and Satsuma-Iwo-jima) over the past 306 years (from AD 1700 to AD 2005). Nine of the 11 events occurred during inactive phases of solar magnetic activity (solar minimum), which is well indexed by the group sunspot number. This strong association between eruption timing and the solar minimum is statistically significant to a confidence level of 96.7%. This relationship is not observed for eruptions from volcanoes with relatively silica-poor magma, such as Izu-Ohshima. It is well known that the cosmic-ray flux is negatively correlated with solar magnetic activity, as the strong magnetic field in the solar wind repels charged particles such as galactic cosmic rays that originate from outside of the solar system.

The ocean floor and volcanic islands such as the Hawaii archipelago are made of basalt, a black rock that in its molten form is the "mother fluid" of the 4.5 billion-year-old Earth. How it gave rise to the silica-enriched rock that formed the continents 2.5 billion years ago is a crucial question in geology.



Here in Hawaii we should be prepared for volcanic eruptions even more that usual since the conditions that our sun are in has been described as an extended solar minimun and our volcanoes are silica-enriched rock . For reference to solar inter actions with earth you can view this link(below), and follow his suggested research(links) into thy science behind this reality.

I love science. So much better than religion.

This has nothing to do with hawaiian volcanoes. Nice try.

Opihikaobob is a "fringe" theorist and everyone who pays attention to his posts can clearly tell.

A lot of websites with .COM extension are just that, Commercial/business websites so do your own research

this all reminds me of the movie "2012" and has little scientific value however some of the researchers have valid credentials; on the other hand reaching "96.7 certainty" after loosely and inaccurately observing (due to lack of technology) for a few centuries the sun cycles is laughable at best given the earth is over 4 BILLION years old.

so in my opinion this is BS Opihikaobob however I do wish one day you strike gold and don't get discouraged Smile

Kilauea is a low silica volcano and is characterized by long periods of slow flowing magma. It is possible to have an explosive eruptive event - some times caused by water getting into a magma chamber and causing a steam powered rush of magma to the surface.

should we be worried or do something?

I don't think you should worry or do anything, it's just more confused scaremongering.

The solar magnetic field is at its strongest when solar activity is at a minimum. Bob says "the conditions that our sun are in has been described as an extended solar minimun" which implies the magnetic field is strong. Cosmic rays are deflected away from the Earth by the Sun's magnetic field and solar wind, so his own argument contradicts itself. On the other hand, if Hawaiian volcanic eruptions are correlated with solar maxima, as they should be according to Bob, then we can check that:

Solar maxima years: ~2013, 2000, 1989, 1979, 1968, 1958, 1947, 1937, 1928, 1917, 1906...

Kilauea eruption years: 1983, 1960, 1959, 1924...

Mauna Loa eruption years: 1984, 1975, 1950, 1949, 1942, 1940, 1935, 1933, 1926, 1919, 1916, 1914, 1907, 1903...

Don't see much correlation there.

Yes, thank you Tom for your attention to facts.

OBob also misread the Washington Post regarding our lava composition. The article stated the island is constructed out of silica-poor basalt. The interesting aspect of Ormat drilling into the small (300' diameter X 50' thick) lava pool was that its composition was silica-rich, a glassy material, very different from our typical lava. According to the geologists, the silica-rich composition is more characteristic of continental rock than our usual island rock.
