Ashfall may originate directly from a volcanic eruption, or indirectly by wind suspending the ash. ASLAbove Sea LevelASOSAutomated Surface Observing System.
FIREWHIRL A tornado-like rotating column of fire and smoke created by intense heat from a forest fire or volcanic eruption.
The magnitudes of some volcanic eruptions in the Northern Hemisphere have been estimated from the acidity of annual layers in ice cores taken in Greenland. This methodology is sometimes referred to as acidity signal or acidity record.
Volcanic AshFine particles of mineral matter from a volcanic eruption which can be dispersed long distances by winds aloft. The chemical composition and abrasiveness of the particles can seriously affect aircraft and also machinery on the ground.
Underwater volcanic eruptions and landslides can also cause tsunami. The resultant waves much the same as waves propagating in a calm pond after a rock is tossed.
volcanic eruptions, erosion). NASA's MTPE uses space-, aircraft-, and ground-based measurements to provide the scientific basis for understanding global change.
Volcanic eruptions directly inject large quantities of H2S or SO2 into the stratosphere, causing large increases in the amount of particulate sulfuric acid.
volcanic aerosol - The cloud of particles injected into the stratosphere by explosive volcanic eruptions.
TSUNAMI An ocean wave with a long period that is formed by an underwater earthquake or landslide, or volcanic eruption.

An ocean wave produced by a sub-marine earthquake, landslide, or volcanic eruption. These waves may reach enormous dimensions and have sufficient energy to travel across entire oceans.

Tsunami - A Japanese term for an unusually large ocean wave caused by undersea earthquake, landslide, or volcanic eruption. Only a few inches high in the open ocean, tsunamis steepen and rise in shallow water and can reach heights of 200 feet.
Apart from weather conditions, AMeDAS is also used in the observation of natural disasters. Temporary observation points are set up in areas where there are signs of volcanic eruptions or earthquakes.

OZONE: There are fluctions from volcanic eruptions. 19. OZONE: The Ozone Hole forms only in Antarctica due to the rare winter conditions. 20. OZONE: Used over 100 yrs. to purify water. Acts 3000 times faster than chlorine.
