Ambrym Island is the summit of a massive volcano in the Republic of Vanuatu. Vanuatu is an archipelago of volcanic islands approximately 2,000 kilometers (1,200 miles) east of Australia, and 1,600 km (1,000 miles) north of New Zealand. A 12-km (7.5-mile)-wide caldera lies at the center of the island, which rises 1,334 meters (4,377 feet) above sea level. Ambrym’s caldera is the site of two active craters: Benbow and Marum. Small eruptions occur frequently at both craters, and volcanic plumes are often visible in satellite imagery.
This natural-color image was acquired by the Moderate Resoution Imaging Spectroradiometer (MODIS) aboard the Terra satellite on the morning of May 22, 2011. A blue-tinged volcanic plume, likely rich in sulfur dioxide, extends from Ambrym Island towards Malekula to the west.

The steep-walled craters of the Marum cone complex at the summit of Ambrym volcano are seen from the east. Ambrym, a large basaltic volcano with a 12-km-wide caldera, is one of the most active volcanoes of the New Hebrides arc. A thick, pyroclastic sequence, initially dacitic, then basaltic, overlies lava flows of a pre-caldera shield volcano. Post-caldera eruptions, primarily from Marum and Benbow cones, have partially filled the caldera floor and produced lava flows that ponded on the caldera floor or overflowed through gaps in the caldera rim.

Vog is a form of air pollution that results when sulfur dioxide and other gases and particles emitted by an erupting volcano react with oxygen and moisture in the presence of sunlight. The word is a portmanteau of the words "volcanic" and "smog". The term is in common use in the Hawaiian islands, where the Kīlauea volcano, on the island of Hawaiʻi, has been erupting continuously since 1983. Based on June 2008 measurements, Kīlauea emits 2,000 - 4,000 tons of sulfur dioxide every day.




Vog es una forma de contaminación atmosférica que se produce cuando los gases de dióxido de azufre y otras partículas emitidas por un volcán en erupción reaccionan con el oxígeno y la humedad, en presencia de luz solar. La palabra es un acrónimo de las palabras "smog" y "volcánica". El término es de uso común en las islas de Hawai, donde el volcán Kilauea, en la isla de Hawai, ha estado en erupción continua desde 1983. Con base en mediciones de junio de 2008, Kilauea emite 2.000 -. 4.000 toneladas de dióxido de azufre cada día.
