"2018's biggest volcanic eruption of sulfur dioxide." These are external links and will open in a new window The government of Vanuatu told reporters that the island had been completely evacuated by 14 August. The Vanuatu Government declared a state of emergency leading to the mass evacuation of the island’s 11,000 population, including 5, Terra / MODIS satellite image of the Aoba (Ambae) volcano eruption. Over the course of the year, the island's entire population of 11,000 was forced to evacuate.At the Ambae volcano's peak eruption in July, measurements showed the results of a powerful burst of energy that pushed gas and ash to the upper part of the troposphere and into the stratosphere, at an altitude of 10.5 miles. Since the eruption of Manaro Voui volcano, the Government of Vanuatu has encouraged people from Ambae to find places to live on other islands.
Populations on Ambae and a neighboring island could hear the eruption, smell the volcanic gases, and see incandescence at night.On 16 July the Darwin VAAC reported an ash plume to 9.1 km that drifted to the NE. Volcanologists who made their way to the area reported widespread damage (figure 84). Residents are being moved to neighbouring islands.One Ambae resident told media outlet news.com.au that it had been hard to sleep because of noise from the volcano, adding that the ash was aggravating children's asthma. But people don’t want to permanently leave the land that is part of their identity. ScienceDaily, 28 February 2019. OMPS measures these signatures, which are then converted, using complicated algorithms, into the number of SO2 gas molecules in an atmospheric column. The uncertainty around the volcano adds greater difficulty.
So, despite the risks, many have returned to Ambae.Moses is the Area Administrator for East Ambae. www.sciencedaily.com/releases/2019/02/190228113547.htm (accessed August 11, 2020).Below are relevant articles that may interest you. ScienceDaily. And while none of the smaller eruptions have had measurable climate effects on their own, they may collectively impact the climate by sustaining the stratospheric aerosol layer. Therefore, the Ambae volcano Alert Level was lowered from Level 2 to Level 1 on the 23rd of September 2019. Ambae volcano is a very large volcano and is frequently active. Terra / MODIS satellite image of the Aoba (Ambae) volcano eruption. Sulfur dioxide is short-lived in the atmosphere, but once it penetrates into the stratosphere, where it combines with water vapor to convert to sulfuric acid aerosols, it can last much longer -- for weeks, months or even years, depending on the altitude and latitude of injection, said Simon Carn, professor of volcanology at Michigan Tech.In extreme cases, like the 1991 eruption of Mount Pinatubo in the Philippines, these tiny aerosol particles can scatter so much sunlight that they cool the Earth's surface below.The map above shows stratospheric sulfur dioxide concentrations on July 28, 2018, as detected by OMPS on the Suomi-NPP satellite.

"The OMPS nadir mapper instruments on the Suomi-NPP and NOAA-20 satellites contain hyperspectral ultraviolet sensors, which map volcanic clouds and measure sulfur dioxide emissions by observing reflected sunlight. He is one of the people who returned. Volcanic ash has covered large parts of the small island
