Wide binary stars show 30–40% unexpected acceleration at ultra-low rates below 0.1 nanometers/second²
While these earthquakes are not impacting Kilauea, one of the world’s most active volcanoes, it has been intermittently erupting since Dec. 23.
According to the latest update from the Hawaiian Volcano Observatory, the intensity of these eruptions, so-called “lava fountaining,” has strengthened after weakening in the days after the initial eruption.
Webcam observations by USGS scientists show that these eruptions are currently confined to its crater.
The processes that haul gold up to the surface from deep within Earth’s mantle rely on the sulfur that bubbles beneath active volcanoes.
Two new papers have agreed that some forms of sulfur form molecular bonds with gold that would otherwise remain sequestered in the mantle, allowing the precious element to rise.
What they don’t quite agree on is which form of sulfur is most important.
