The Ash product is an RGB (Red, Green, Blue) composite based upon infrared channel data from the Meteosat Second Generation satellite. It is designed to detect ash and sulphur dioxide (SO2) from volcanic eruptions which can be used for the provision of warnings to aviation authorities.

The polar-orbiting Joint Polar Satellite System (JPSS) satellites, along with the GOES ABI sensor, enable more precise observations of SO₂ atop volcanic clouds. NOAA also operates two Volcanic Ash Advisory Centers (VAACs) which are among nine centers worldwide, covering advisories for the U.S., Latin America, and the West Pacific.
7 lut 2018 · Volcanic ash. This amorphous, inorganic—i.e., non-carbon based—silicate is obtained from lava deposits. It is indicated for product thickening benefits and absorption properties; for example, to absorb sebum and lipids. It also has reported skin-conditioning benefits. Lava extract and powder.
Volcanic ash is a far-reaching hazard that can affect structures, power generation and transmission, water districts, ground and air transportation, agriculture, and human health. The USGS Volcano Hazards Program offers several resources aimed at forecasting, remediating, and reporting volcanic ash.
Dry volcanic ash can stick to a moist human eye, and the tiny ash particles quickly cause eye irritation. This problem is most severe among people who wear contact lenses. Some skin irritation is reported by people in ashfall areas; however, the number of cases and their severity are low.
