Mars rovers safe from lightning strikes, research finds

If experiments done in small bottles in a University of Oregon lab are accurate, the friction of colliding Martian dust particles are unlikely to generate big electrical storms or threaten the newly arrived exploration vehicles ...

Synchronization of ice cores using volcanic ash layers

Thin, brownish layers of a thickness of about a millimeter or two are sometimes observed in the whitish/transparent ice cores. These brown layers consist of material originating from volcanic eruptions.

Chaos theory provides a way for determining how pollutants travel

Floating air particles following disasters and other largescale geological events can have a lasting impact on life on Earth. Volcanic ash can be projected up to the stratosphere and halt air traffic by lingering in the atmosphere ...

Volcanic ash particles under the microscope

Volcanic ash is hazardous to many aspects of our lives. When airborne, it can damage aircraft: its particles abrade aeroplane surfaces and can even cause failure to critical instruments. Once the ash falls, it can harm our ...

'It smelled like sulfur:' Ash falls near Hawaii volcano

Hawaii residents covered their faces with masks after a volcano menacing the Big Island for weeks exploded, sending a mixture of pulverized rock, glass and crystal into the air in its strongest eruption of sandlike ash in ...

Light coats of gritty ash fall near erupting Hawaii volcano

Authorities handed out around 2,000 masks for protection as people living near Hawaii's Kilauea volcano braced for pulverized rock, glass and crystal to rain down after an explosive eruption at the peak's summit.

Red sky in sight shows charging at height

The Saharan dust cloud that cast a red glow over the UK last autumn helped scientists to take a step forward in understanding how to prepare for future volcanic eruptions.
