Hawaii volcano sending compasses crazy. Could be signaling an upcoming polarity reversal.
Mount Kilauea’s magnetic field flows in the opposite direction to the rest of the planet, sending compasses into an “uncontrollable spin.” according to the Express.
(I know, I know, the Express is not one of the most dependable of sources, but when it quotes scientists who say our planet is rapidly approaching a magnetic reversal, I sit up and take notice.)
Brad Singer, a geology professor at the University of Wisconsin–Madison, who investigates lava flow magnetic fields, explained the bizarre finding: “When the lava flows erupt and cool in the Earth’s magnetic field, they acquire a memory of the magnetic field at that time. The flip occurs during periods of declining strength of the Earth’s magnetic field, Singer added.
(I agree. That’s what I say in Not by Fire but by Ice.)
“Right now, historic records show that the strength of the magnetic field is declining very rapidly,” said Singer. “From a quick back-of-the-envelope prediction, in 1,500 years the field will be as weak as it’s ever been and we could go into a state of polarity reversal.
(I think it could happen far sooner than that.)
Co-researcher Kenneth Hoffman of California Polytechnic State University at San Luis Obispo and UW–Madison has been researching field reversals for over 30 years.
