Some scientists have suspected a volcanic winter resulting from the eruption was a big enough shift to wipe out most early humans due to genetic evidence suggesting a steep drop in the human ...
Tephra is a generalized word for the various bits of debris launched out of a volcano during an eruption, regardless of their size. [4] Pyroclastic materials are generally categorized according to size: dust measures at <1/8 mm, ash is 1/8–2 mm, cinders are 2–64 mm, and bombs and blocks are both >64 mm. [5] Different hazards are associated with the different kinds of pyroclastic materials.
A.D. 79: Mount Vesuvius, Italy. Mount Vesuvius has erupted eight times in the last 17,000 years, most recently in 1944, but the big one was in A.D. 17. One of the most violent eruptions in history ...

The volcano released approximately 150,000 tonnes of CO 2 each day, or approximately 4.5 million tonnes of carbon dioxide by 19 April 2010. The massive reduction of air travel occurring over European skies caused by the ash cloud, saved an estimated 1.3 to 2.8 million tonnes of carbon dioxide from entering the atmosphere by 19 April 2010.
A small but restive volcano near the Philippine capital Manila spewed above average sulfur dioxide and volcanic smog on Friday, prompting authorities to closes schools in five cities and dozens of ...
A region of about 100 square kilometres (39 sq mi) was hit by the effects of the eruption. [25] The ash fall from the eruption caused health problems and disrupted pastures and agriculture in the region around the volcano, resulting in about US$1,000,000 of damage [95] and the flight of local residents to Arequipa and Moquegua. [94]
Volcanic aerosols from huge volcanoes (VEI>=5) directly reduce global mean sea surface temperature (SST) by approximately 0.2-0.3 °C, [1] [3] milder than global total surface temperature drop, which is ~0.3 to 0.5 °C, [4] [5] [6] according to both global temperature records and model simulations. It usually takes several years to be back to ...
