Study justifies closing airports in volcano event

The disruptive closing of some European airports after last year's volcanic eruption in Iceland was the right thing to do and may have saved lives, a new study concludes.

The ashes of Mt. St. Helens

The massive eruption of Mt. St. Helens 35 years ago is one of the largest ever seen in North America. LMU volcanologists now report a retrospective analysis of salts leached from the ash deposited by the volcano on that occasion.

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.

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 ...

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.

Scientists better prepared to judge ash cloud

Scientists say they are now better prepared for measuring Iceland's volcanic ash problem, which is expected to continue for several months, after experiments using modelling and lasers to probe the atmosphere.

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.

Don't build your model on sand

Volcanic ash can damage jet engines, and Ludwig-Maximilians-Universitaet (LMU) in Munich volcanologists have developed a new empirical model for assessment of the risk. Their results show that tests using sand do not reflect ...

Shedding light on plumes

Ludwig Maximilian University of Munich researchers have shown that volcanic lightning results from the discharge of static electricity accumulated by ash particles in the rising plume. Observations of such flashes could help ...
