This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536); its effect on the climate may have been exacerbated by the 1814 eruption of Mayon in the Philippines. The significant amount of volcanic ash and gases released into the atmosphere blocked sunlight, leading to global cooling.
Volcanic ash can have a detrimental impact on the environment which can be difficult to predict due to the large variety of environmental conditions that exist within the ash fall zone. Natural waterways can be impacted in the same way as urban water supply networks.
An Ashfall advisory is a weather advisory issued by the National Weather Service of the United States.Ashfall advisories are issued when there is a likely future or present occurrence of ash rain caused by a large plume of suspended airborne ash, typically caused by large fires or volcanic activity.

A volcanic eruption is one of the most powerful forces in nature, a seemingly unstoppable phenomenon that can have far-reaching impacts far beyond the area surrounding the volcano itself. When a ...
Mount Kanlaon, an active volcano straddling the central provinces of Negros Occidental and Negros Oriental, sent an ash cloud up to 4,000m into the sky at about 3pm (local time). Kanlaon is one of ...
Mexico’s most dangerous active volcano spewed ash and smoke on Tuesday, with photos showing massive columns of gray emissions – large enough to ground nearby flights.
The Philippines is projected to be one of the most vulnerable countries to the impacts of climate change, [5] which would exacerbate weather extremes. As the Philippines lies on the Pacific Ring of Fire, it is prone to natural disasters, like earthquakes, typhoons, and volcanic eruptions.
Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. Often, when a volcano explodes, biological organisms are killed and their remains are buried within the tephra layer.
