Using smartphones to create distributed space weather observatory

A study by NASA astronomer Sten Odenwald found that magnetometers in smartphones can detect small disturbances of the Earth's magnetic field, allowing such devices to be used to form a distributed space weather observatory. The 3-axis Hall-effect magnetometer...

Scientists confirm existence of Alfven Waves, magnetic waves in the Sun's photosphere

Researchers have confirmed the presence of magnetic plasma waves in the Sun's photosphere, catching them in action. Known as Alfven Waves, these fascinating waves were first predicted in 1947. The Alfven Waves, named after Nobel Prize-winning scientist Hannes...

Large earthquake could trigger eruption of Mauna Loa, world's largest active volcano

Scientists from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science have shed light on the hazards of Hawaii's Mauna Loa, the largest active volcano on Earth, finding that a large earthquake could set off an eruption. The team...

Longest underwater avalanche monitored in action continuously self-accelerated for over 1 000 km

In a new paper, scientists have reported what they say is the longest sediment avalanche measured so far in action and the only monitored flow to continuously self-accelerate for over 1 000 km (620 miles). The event occurred off the coast of West Africa, in a deep...

New study solves mystery behind Earth's deepest earthquakes

The cause of the deepest earthquakes on Earth has been a mystery to scientists for more than a century. In a new study, a team of scientists may have solved the case by identifying water as the key factor that causes deep-focus quakes. Most earthquakes occur near...

Supervolcanic eruption of Toba destroyed ozone layer, causing population bottleneck

A catastrophic drop in atmospheric ozone layers 60 000 to 100 000 years ago likely contributed to a population bottleneck during that period. According to a new study, the event was triggered by the eruption of the Toba supervolcano in Sumatra, Indonesia. "Toba...

World's longest recorded earthquake lasted for 32 years

The devastating M8.5 earthquake that shook Sumatra, Indonesia, in 1861 was long believed to be a sudden rupture on a previously quiescent fault. However, new research showed that tectonic plates below the island had been slowly crashing against each other for 32...

Scientists identify new atmospheric circulation over the Arctic

A team of scientists from Japan, South Korea, and the USA, has identified a new pattern of atmospheric circulation around the Arctic that could drive co-occurrences of heatwaves and large-scale wildfires over the region, particularly in Siberia and subpolar North...

Study reveals inner workings of slow-slip earthquakes

Slow-slip earthquakes have been detected at many earthquake hotspots in the world, including areas around the Pacific Ring of Fire, but it remains unclear as to how they are linked to the damaging quakes that take place there. In a new study, researchers at The...

Electromagnetic anomalies occurring before large earthquakes

A new study published in Earth, Planets and Space sheds new light on the electromagnetic anomalies occurring before large earthquakes. The research supports the hypothesis that fault rupture progresses just before an earthquake, and the invading gas is charged and...

Situational awareness for potentially hazardous comets last near-Earth as far back as 4 000 years ago

SETI Institute researchers are reporting that they can now detect showers from the debris in the path of comets that pass close to Earth orbit and are known to return as infrequent as once every 4 000 years. "This creates a situational awareness for potentially...

Decades-old video footage reveals new type of aurora - Diffuse Auroral Eraser

Decades-old video footage has shown a never-before-seen aurora, which scientists at the University of Iowa called the Diffuse Auroral Eraser. This elusive type of aurora first appears as a brighter stripe within a fainter, more diffused aurora. When the stripe...
