Erupting the magma chamber paradigm

electricity volcano magma chambers lightning

The end of localised magma chambers being the only natural power source for volcano eruptions? Natural electrochemistry processes. The formation, storage and chemical differentiation of magma in the Earth’s crust is of fundamental importance in igneous geology and volcanology. Recent data are challenging the high-melt-fraction ‘magma chamber’ paradigm that has underpinned models of crustal magmatism …

Volcanic Lightning

Volcanic lightning from or to volcanic plumes and dirty thunderstorms is always impressive. In the National Geographic 2017 photography competition these electrical discharges even won the categories of Nature and Grand Moff Winner. Where does the massive amounts of electromagnetic energy come from? And all the chemical elements? In a circuit to all those plasma …

Dirty thunderstorms – Mount Etna

dirty thunderstorms volcano lightning storm sicily eu theory electric discharge

A dirty thunderstorm (volcanic lightning or dirty lightning?) was created above the latest Mount Etna eruption and a video of the time lapse photographs can be seen below. Why do all volcano eruptions not produce dirty thunderstorms and the volcanic lightning? Or do they but it has only just started to be recorded? If lightning …

Volcanic explosions – unique electrical activity

electric volcanoes lightning univere theory eu origin

Dirty thunderstorms can create lightning associated with volcanoes, as suggested for the volcanic lightning photographed at the Halemaumau Crater in the Hawaii Volcanoes National Park. Dust (rock particles) rubbing together is suggested as creating the awesome amounts of static electricity to produce these electric discharges, similar to lighting from thunderstorms – dirty thunderstorms. But an …

Volcano lightning glass

Volcano lightning glass spherules volcanic tektites

The spectacle of volcano lightning may include the creation of volcano lightning glass spherules. The lightning-induced volcanic spherules study reports finding volcanic lightning glass in a few recent volcanic eruptions, or at least proposes a mechanism for its formation. reveal individual glass spherules ∼50 μm in average diameter that compose
