On September 4, 2012 a NASA satellite captured an image of lava flowing down Anak Krakatau.
Anak Krakatau, or Child of Krakatau, the Earth Observing-1 (EO-1) satellite on the morning of September 4, 2012.
It’s said that the sound created by the 1883 explosion was the loudest sound heard in modern history. Though Krakatau essentially disappeared from the ocean’s surface in 1883, subsequent undersea eruptions eventually rebuilt the island.
Anak Krakatau currently has a radius of about 2 kilometers (6562 feet) and a height of 324 meters (1063 feet) above sea level, according to Wikipedia.
Anak Krakatau is growing in height at an average rate of about 5 meters (16 feet) per year. Bottom line: On September 4, 2012 NASA’s Earth Observing-1 satellite captured an image of lava flowing down the southeastern flank of the Anak Krakatau. The 1883 eruption of Krakatoa was equivalent to an explosion of 200 megatons of TNT, about 13000 times the yield of the Little Boy bomb which devastated Hiroshima, Japan. Still, the most violent volcano on Earth is considered Tambora (2,865m or 9,550ft tall) from the Sumbawa Island (Indonesia). But perhaps the most amazing Indonesian volcano is Kawah Ijen (2,600m or 8,660ft tall), the "Green Crater" from western Java, which has a lake made of 36 million cubic meters representing a solution of sulfuric acid and hydrogen chloride, the most powerful existing acids. On the edges of the lake, the fumaroles (volcanic gas eruptions) depose 4 tonnes of sulfur daily.
The walls of the Kawah Idjen lake are light ocher, but the water has a turquoise color, with emerald reflexes.
The lake contains 600,000 tonnes of hydrogen chloride, 550,000 tonnes of sulfuric acid, 200,000 tonnes of aluminium sulphate and 170,000 tonnes of iron sulphate. People from the neighboring area extract sulfur from the crater manually - an extremely hard work.

In the irritating and corrosive atmosphere of the crater, people's only protection is a piece of fabric used for covering their mouths and noses.
Industrial exploitation of the lake has not been planned so far, as the volcano erupts from time to time, projecting acid to the height of 600 m (2,000 ft) and splashing the neighboring areas with a corrosive rain.
In 1976, 50 people were surprised inside the crater by an enormous bubble of sulfuric dioxide, which, after raising the surface of the lake, killed 11 of them by asphyxiation. The volcano is located just east of Jakarta, Indonesia in the Sundra Strait between the islands of Java and Sumatra. Strombolian eruptions are characterized by fountains of basaltic lava caused by the release of pressurized volcanic gases.
Before the historic 1883 eruption, Anak Krakatau stood at approximately 813 meters (2667 feet) above sea level, according to the Global Volcanism Program.
The fresh lava is estimated to have extended the shoreline of the volcanic island by about 100 meters (330 feet), according to a report issued by NASA’s Earth Observatory. Krakatoa, located on an island in the Sunda Strait between Java and Sumatra in Indonesia, is well known because of its 1883 eruption, which generated the loudest sound historically reported: it was distinctly heard even in the Australian city of Perth (approx.
On 10th of April 1815, the mountain blew out ejecting its peak into the atmosphere at a height of 1,250m (4,160ft)! Such acid lakes are also found on the volcanoes Kusatsu-Shirane (Japan) and Poas (Costa Rica), but the Indonesian lake is by far the largest acid lake on Earth, having a maximum depth of 212m (706ft). To increase efficiency, the workers build tunnels of stone and undulated plates to channel the sulfur-rich fumaroles. Each worker can transport 40 to 70kg (90 to 155 pounds) at once on the abrupt slopes of the volcano, using bamboo ladders where the slope is too steep. Today, the new volcanic island that has formed is known as Anak Krakatau, which is Indonesian for ‘child of Krakatau’.
This type of eruption was named after the Stromboli volcano, located north of Sicily, Italy.

These lakes result from the mix of rainfall water with gases coming from the depths of the volcano. The sulfur then leaks, cools down and solidifies inside these improvised channels, which are subsequently broken using metal piles. The daily production of the exploitation is just of 4 tonnes, a derisory quantity, if we consider the fact that the crater harbors 30,000 tonnes of sulfur.
Her interest in toxicology stems from having grown up near the Love Canal Superfund Site in Western New York. The sulfur is transported to Banjuwangi, 37 km (23 mi) away and it will be used for vulcanizing rubber or refining sugar. The aim of her current work is to provide high-quality scientific information to the public and decision makers and to build cross-disciplinary partnerships to help solve environmental problems.
About 150-180 cubic kilometers of debris were projected into the stratosphere, dimming the sky and depriving the Northern Hemisphere of summer. From place to place, sulfur pours at a temperature of 120o C, like bright red trails, which gradually solidify, turning lemon yellow.
The sulfur is made into pieces, loaded in baskets and transported on the men's back outside the crater.
