Even when a volcano is quiet, steep volcanic slopes can collapse to become landslides, and large rocks can be hurled by powerful steam blasts. An estimated 15 cubic kilometers of magma was explosively erupted during 60 hours beginning on June 6th. Werner explained how the lake became so acidic: The volcano emitted hydrogen chloride gas, which reacted with the water and formed a highly condensed hydrochloric acid with a pH of almost 0.

Retrieved from https://www.thoughtco.com/how-blue-lava-works-607589. "To double their meagerincome, the hardiest of these men work nights, by the electric blue light of the sulfuric acid exhaled by the volcano," Grunewald says. In modern times, volcanic phenomena have attracted intense scientific interest, because they provide the key to understanding processes that have created and shaped more than 80 percent of the Earth's surface. The discovery of a fossil horse tooth in Haiti has given surprising credence to the idea the horses escaped from a Spanish shipwreck off Virginia around 1750. Some of the miners do have gas masks that visitors have given them, said Grunewald, but they "have no money and no opportunity to change the filters.
Since it was mentioned on TV (National Geographic to be precise) the number of tourists who travel to East Java and Indonesia has significantly increased.

Horrific summer travels? These tales are worse. Workers who collect and sell the sulfur typically do not wear protection, so you can leave your mask for them when you leave. He describes working on the challenging project saying: The main problem was the acidic gases that whirled constantly in the crater.
Although the Kawah volcano is most readily accessible, other volcanoes in the Ijen may also produce the effect. Miners have been extracting sulfur here for more than 40 years. Red is even cooler, about 600800 degrees Celsius (1,1121,472 degrees Fahrenheit). Werner noted that forest fires in Yellowstone National Park have caused similar "rivers," as heat from the blazes melted the sulfur around hydrothermal vents. The eruption temperature of Klauea lava is about 1,170 degrees Celsius (2,140 degrees Fahrenheit). Some people even call it electric blue fire. It does not only require agility and strength to walk up and down the volcano's steep slopes, but workers are also exposed to the toxic sulfur gases for long periods of time. The heat of magma sometimes ignites the sulfur dust in the soil, forming flames of electric blue. As the burning gases cool, they deposit sulfur around the lake. Kawah Ijen volcano is the subject of a new documentary released earlier this month that was produced by Grunewald and Rgis Etienne, the president of Geneva's Society of Volcanology.

Some of the workers arechildren, seeking to support their families by any means possible. How do lava flows cool and how long does it take? Orange indicates a slightly cooler temperature of about 8001,000 degrees Celsius (1,4721,832 degrees Fahrenheit). The glow is actually the light from the combustion of sulfuric gases, Grunewald explained. Most include a college or graduate school education in a scientific or technical field, but the range of specialties is very large. Here are some temperatures recorded at different times and locations: Yellowstone is a plateau high in the Rocky Mountains, and is snowbound for over six months per year.

Helmenstine, Anne Marie, Ph.D. (2021, February 16). These d, Klauea Volcano, on the Island of Hawaii, is surrounded and permeated by active groundwater systems that interact dynamically with the volcanic system. Miners extract the sulfur rock, which is formed after the blue flames extinguish leaving behind a solid sulfur-rich rock. "The vision of these flames at night is strange and extraordinary," Grunewald says. If you are using an Ad-Blocker, it might have mistakenly blocked our content. His photos make the blue flames appear dramatically beautiful, even surreal. "I have also seen the miners spraying water from a small pump onto the pipes to promote cooling and condensation," said Pallister via email. "The main problem was the acidic gases that whirled constantly in the crater," he says. Here's a look at the chemical composition of the blue stuff and where you can go to see it. Little of the web coverage, though, has enlightened readers on the scientific principles at work. Grunewald first heard about the phenomenon from Etienne, who visited the volcano in 2008 with an Indonesian guide. Howard, Brian Clark (January 30, 2014).
