The more I look at those pics the more unreal they look, they put any special effects in movies to shame
True,they look so shiny that you can´t believe they are real Volcanic eruptions by VEI index[6] VEI Plume height Eruptive volume * Eruption type Frequency ** Example 0.<100 m (330 ft) 1,000 m3 (35,300 cu ft) Hawaiian Continuous Kilauea 1.100–1,000 m (300–3,300 ft) 10,000 m3 (353,000 cu ft) Hawaiian/Strombolian Months Stromboli 2.1–5 km (1–3 mi) 1,000,000 m3 (35,300,000 cu ft) † Strombolian/Vulcanian Months Galeras (1992) 3.3–15 km (2–9 mi) 10,000,000 m3 (353,000,000 cu ft) Vulcanian Yearly Nevado del Ruiz (1985) 4.10–25 km (6–16 mi) 100,000,000 m3 (0.024 cu mi) Vulcanian/Peléan Few years Eyjafjallajökull (2010) 5.>25 km (16 mi) 1 km3 (0.24 cu mi) Plinian 5–10 years Mount St. Helens (1980) 6.>25 km (16 mi) 10 km3 (2 cu mi) Plinian/Ultra Plinian 1,000 years Krakatoa (1883) 7.>25 km (16 mi) 100 km3 (20 cu mi) Ultra Plinian 10,000 years Tambora (1815) 8. >25 km (16 mi) 1,000 km3 (200 cu mi) Ultra Plinian 100,000 years Lake Toba (74 ka) * This is the minimum eruptive volume necessary for the eruption to be considered within the category. ** Values are a rough estimate. Exceptions occur. † There is a discontinuity between the 2nd and 3rd VEI level; instead of increasing by a magnitude of 10, the value increases by a magnitude of 100 (from 10,000 to 1,000,000).
The authorities were forced to evacuate 3500 inhabitants and declare the maximum - the "red" - the level of threat, and in neighboring Argentina partially disrupted air traffic.
