When volcanos erupt, these geologic monsters produce tremendous clouds of ash and dust—plumes that can blacken the sky, shut down air traffic and reach heights of roughly 25 miles above Earth's ...

DURHAM, N.C. - Scientists at Duke University have developed a suite of four new tests that can be used to detect coal ash contamination in soil with unprecedented sensitivity. The tests are ...

Volcanic ash poses "engine flameout" hazard to aircraft due to hard, abrasive particles In 1989, a Boeing 747 (KLM Flight 867) Amsterdam-Tokyo flight flew into a volcanic ash cloud from Redoubt ...

A new aerodynamic analysis suggests that small particles of ash in a turbulent volcanic plume can fall nearer their source than researchers had thought. On Aug. 18, 1992, Mount Spurr–a ...

Volcanic ash shuts down air traffic and can sicken people. But a new study suggests that it may also be more important for Earth's climate than scientists once thought. When volcanoes erupt, these ...
