The NOAA/CIMSS Volcanic Cloud Monitoring web site features near real-time processing of many geostationary and low-earth orbit satellites covering much of the globe. The content within the …

The USGS provides forecasts of expected ash dispersion (ash clouds) and deposition (ash fall) from volcanic eruptions using a numerical atmospheric transport model called Ash3D that was …

The erupting lava cooled very fast, which created a cloud of highly abrasive, glass-rich ash. The volcano's explosive power was enough to inject ash directly into the jet stream.

The principal damage sustained by aircraft flying into a volcanic ash cloud is abrasion to forward-facing surfaces, such as the windshield and leading edges of the wings, and accumulation of …

During an actual eruption, see National Weather Service forecasts of airborne ash hazard to aircraft (SIGMETS:https://weather.gov/aawu/and Volcanic Ash …

May 12, 2016 · NASA scientist Nickolay Krotkov is developing a new way to map the full three-dimensional structure of the volcanic cloud. The NASA/NOAA/DoD Suomi NPP satellite maps …

When a volcano erupts explosively, an ash cloud will be produced. Its size and travel-distance are determined by the amount of material erupted, the height of the cloud, plus the wind directions …

Apr 16, 2019 · The VOLcanic Cloud Analysis Toolkit (VOLCAT) is a collection of software developed by NOAA, in partnership with the University of Wisconsin‐Madison. VOLCAT …

As a result of its fine-grained abrasive character and widespread distribution by wind, ashfall and volcanic ash clouds are a major hazard to aviation. The primary hazard from Alaska volcanoes …
