Making sense of commotion under the ocean to locate tremors near deep-sea faults

Researchers have developed a new method for detecting small earthquake tremors and successfully applied it to the Nankai Trough, Japan. The technique allowed the accurate estimation of tremor location and propagation speed, leading to the first estimates of this fault’s permeability — crucial information in evaluation of earthquake rupture processes.

How do you know where volcanic ash will end up?

Until the eruption of Eyjafjallajökull volcano, models from the VAACs were based on the tracking of the clouds in the atmosphere. In the wake of this economic disaster for airlines, ash concentration levels have been introduced to make decisions on flight restrictions. However, a team discovered that even the smallest volcanic ash did not behave

Volcanoes might light up the night sky of this planet

Until now, researchers have found no evidence of global tectonic activity on planets outside our solar system. Scientists have now found that the material inside planet LHS 3844b flows from one hemisphere to the other and could be responsible for numerous volcanic eruptions on one side of the planet. Title: Volcanoes might light up the

Revisiting the Kobe earthquake and the variations of atmospheric radon concentration

Researchers have unearthed further details about radon concentration in the atmosphere before and after earthquakes, moving us closer to being able to anticipate when large earthquakes may hit.

‘Space hurricane’ in Earth’s upper atmosphere discovered

Analysis of observations made by satellites in 2014 has revealed a long-lasting ‘space hurricane’ — a swirling mass of plasma several hundred kilometers above the North Pole, raining electrons instead of water.

Unusual earthquakes highlight central Utah volcanoes

Earthquakes in the Black Rock Desert are rare and capturing the seismic recordings from these earthquakes provides a glimpse into the volcanic system of the Black Rock Desert that, while not showing any signs of erupting, is still active.

Asteroid dust found in crater closes case of dinosaur extinction

Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater.

‘Missing ice problem’ finally solved

During glacial periods, the sea level falls, because vast quantities of water are stored in the massive inland glaciers. To date, however, computer models have been unable to reconcile sea-level height with the thickness of the glaciers.
