[quote]A huge volcanic eruption in Indonesia has covered the region in a vast cloud of ash, grounding flights in Australia and south east Asia.
Sangeang Api, a volcano off the Indonesian island of Sumbawa, which lies in one of the most active areas of the Pacific ‘ring of fire’, has erupted at least three times since Friday.
Dramatic images show smoke, ash and debris shooting into the sky, while a flying saucer shaped current of gas wraps around the plumes.[/quote]
holy fuck that title is brilliant
Hehe, that title.
That fucking ashcloud though.
Pictures of volcanoes erupting are always so beautiful.
If you look at it just so part of that cloud looks like a flying saucer.

Also I hope everyone there is ok, would this effect peoples health in that area?

[quote]Ash particles of less than 10 µm diameter suspended in the air are known to be inhalable, and people exposed to ash falls have experienced respiratory discomfort, breathing difficulty, eye and skin irritation, and nose and throat symptoms. Most of these effects are short-term and are not considered to pose a significant health risk to those without pre-existing respiratory conditions.The health effects of volcanic ash depend on the grain size, mineralogical composition and chemical coatings on the surface of the ash particles. Additional factors related to potential respiratory symptoms are the frequency and duration of exposure, the concentration of ash in the air and the respirable ash fraction; the proportion of ash with less than 10 µm diameter, known as PM10. The social context may also be important.
Chronic health effects from volcanic ash fall are possible, as exposure to free crystalline silica is known to cause silicosis. Minerals associated with this include quartz, cristobalite and tridymite, which may all be present in volcanic ash. These minerals are described as ‘free’ silica as the SiO2 is not attached to another element to create a new mineral. However, magmas containing less than 58% SiO2 are thought to be unlikely to contain crystalline silica.
The exposure levels to free crystalline silica in the ash are commonly used to characterise the risk of silicosis in occupational studies (for people who work in mining, construction and other industries,) because it is classified as a human carcinogen by the International Agency for Research on Cancer. Guideline values have been created for exposure, but with unclear rationale; UK guidelines for particulates in air (PM10) are 50 µg/m3 and USA guidelines for exposure to crystalline silica are 50 µg/m3.[50] It is thought that the guidelines on exposure levels could be exceeded for short periods of time without significant health effects on the general population.
There have been no documented cases of silicosis developed from exposure to volcanic ash. However, long-term studies necessary to evaluate these effects are lacking.
Ingesting ash may be harmful to livestock, causing abrasion of the teeth, and in cases of high fluorine content, fluorine poisoning (toxic at levels of >100 µg/g) for grazing animals. It is known from the 1783 eruption of Laki in Iceland that fluorine poisoning occurred in humans and livestock as a result of the chemistry of the ash and gas, which contained high levels of Hydrogen Fluoride. Following the 1995/96 Mount Ruapehu eruptions in New Zealand, two thousand ewes and lambs died after being affected by fluorosis while grazing on land with only 1–3 mm of ash fall.[51] Ash ingestion may also cause gastrointestinal blockages.[34] Sheep that ingested ash from the 1991 Mount Hudson volcanic eruption in Chile, suffered from diarrhoea and weakness. The added weight of ash in the wool led to fatigue and sheep could not stand up. The ash from Mount Hudson also caused irrigation channels to become blocked. Surface water ponds are also susceptible to contamination by ash.[/quote]
It kinda looks like a huge toilet.
What if volcanoes are plumbing systems for gods?!

I got reminded of this episode from Dexter's lab;
