On September 10, Kanlaon produced its highest volume of sulfur dioxide emissions since 2009, at 9,985 tonnes, prompting PHIVOLCS to raise concern over its possible first magmatic eruption since 1902. [14] The record was surpassed the next day, when 11,556 tons of sulfur dioxide was emitted. [15]
A volcano in the central Philippines explosively erupted on Monday, prompting the urgent evacuation of at least 87,000 people living within the danger zone as plumes of smoke and ash billowed ...
The Philippines' Kanlaon volcano erupted for nearly four minutes, shooting ash 2.5 miles into the sky and prompting the emergency evacuation of some 87,000 people.
Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur: S 8 + 8 O 2 → 8 SO 2 , ΔH = −297 kJ/mol To aid combustion, liquified sulfur (140–150 °C (284–302 °F) is sprayed through an atomizing nozzle to generate fine drops of sulfur with a large surface area.
Kanlaon, also known as Mount Kanlaon and Kanlaon Volcano (Hiligaynon: Bolkang Kanglaon; Cebuano: Bolkang Kanglaon; Filipino: Bulkang Kanlaon), is an active andesitic stratovolcano and the highest mountain on the island of Negros in the Philippines, as well as the highest peak in the Visayas, with an elevation of 2,465 m (8,087 ft) above sea level.

Smog formation in general relies on both primary and secondary pollutants. Primary pollutants are emitted directly from a source, such as emissions of sulfur dioxide from coal combustion. Secondary pollutants, such as ozone, are formed when primary pollutants undergo chemical reactions in the atmosphere.
The eruption was one of the most powerful of the 19th century, spewing so much sulfur dioxide into the stratosphere that annual average temperatures in the Northern Hemisphere dropped by about one ...
The amount of sulfur dioxide that can be emitted into the atmosphere is capped by the EPA. This reduces the quantity of sulfur dioxide in the air that turns into sulfur trioxide and sulfuric acid. [14] Sulfuric acid concentrations in workroom air are restricted by OSHA to 1 mg/m 3. Moreover, NIOSH advises a time-weighted average limit of 1 mg/m ...
