Is Jupiter's Moon Io Poised to Top Its Titanic Surt Volcano Eruption? --"The Most Powerful Ever Observed in Our Solar System"
In February 2001 an eruption from the Surt volcano on the Jupiter-facing hemisphere of Io, the volcanic epi-center of our solar system, occurred with an estimated output of 78,000 Gigawatts. By comparison, the 1992 eruption of Mt Etna, Sicily, was estimated at 12 Gigawatts. During its peak, observed by the WM Keck II Telescope on Hawaii, its output almost matched the eruptive power of all of Io’s active volcanoes combined.
