Volcanoes

Almost like on Venus

(ETH Zurich) A team of international scientists led by ETH researcher Paolo Sossi has gained new insights into Earth’s atmosphere of 4.5 billion years ago. Their results have implications for the possible origins of life on Earth.

Cascading events led to 2018 Ki?lauea volcanic eruption, providing clues for forecasting

The 2018 eruption of Ki?lauea Volcano was one of the largest volcanic events in Hawai’i in 200 years. This eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study.

Former piece of Pacific Ocean floor imaged deep beneath China

In a study that gives new meaning to the term ‘rock bottom,’ seismic researchers have discovered the underside of a rocky slab of Earth’s lithosphere that has been pulled more than 400 miles beneath northeastern China by the process of tectonic subduction.

Love waves from the ocean floor

Supercomputer simulations of planetary-scale interactions show how ocean storms and the structure of Earth’s upper layers together generate much of the world’s seismic waves. Decoding the faint but ubiquitous vibrations known as Love waves could yield insights about Earth’s storm history, changing climate and interior.

An epidemic outbreak of Mesoamerican Nephropathy in Nicaragua linked to nickel toxicity

For over 20 years, researchers have tried to solve the medical mystery behind Mesoamerican Nephropathy, a form of chronic kidney disease that has caused more than 50,000 deaths in coastal South America. Now, researchers present the strongest evidence to date on the cause of the disease in one of the worst-hit hotspots in the region, Nicaragua, using an unlikely source, the toenails of individuals with the disease.

How Jupiter’s moon Io gets its hellish atmosphere

Hot, active volcanoes produce almost half of Jupiter’s moon Io’s sulfur atmosphere, according to new observations using the ALMA telescope. The rest comes from cold sulfur deposits that freeze on the surface, then sublimate in sunlight.

Crystals reveal the danger of sleeping volcanoes

Most active volcanoes on Earth are dormant and are normally not considered hazardous. A team of volcanologists has devised a technique that can predict their devastating potential. The scientists used zircon, a tiny crystal contained in volcanic rocks, to estimate the volume of magma that could be erupted once Nevado de Toluca volcano (Mexico) will wake up from its dormancy. Up to 350 km3 of magma are currently lying below.

Magma ‘conveyor belt’ fuelled world’s longest erupting supervolcanoes

Geologists have found that a volcanic province in the Indian Ocean was the world’s most continuously active — erupting for 30 million years — fueled by a constantly moving ‘conveyor belt’ of magma.
