Smithsonian institute gives a 6 for one of the eruptions. It is a caldera, so it has to be somewhere in the higher range
The Volcanic Explosivity Index (VEI) is a measure of the explosiveness of volcanic eruptions. It was devised by Chris Newhall of the United States Geological Survey and Stephen Self at the University of Hawaii in 1982. The index is based on a scale of 1 to 8, 1 being very small, and 8 being huge and very rare.
Volcanic eruptions categorized on the Volcanic Explosive Index (VEI) are based on the amount of matter ejected during an eruption. The VEI uses a scale from 0 to 8, with 8 being an eruption ejecting more than 1,000 cubic kilometers of matter and each smaller increment releasing one-tenth the amount of ejected matter. A VEI of 5 would indicate an ejection of more than 1 cubic kilometer of matter, while a VEI of 4 would be greater than 0.1 cubic kilometers and a VEI 6 would be more than 10 cubic kilometers but less than 100 cubic kilometers (VEI 7).
0 to 1, 0 being more common than 1. The reason is that Hawaiian volcanoes aren't very explosive. They produce a lot of lava, but with a continuous flow. VEI index measures explosiveness, with indicators for eruption column height and volume of pyroclastic material produced. Both factors are low for Hawaiian volcanoes.
The Volcanic Explosivity Index (VEI) of Mount Nyiragongo's eruption in 2011 is classified as a VEI 1 event. This indicates a relatively mild eruption characterized by effusive lava flows rather than explosive activity. The eruption primarily involved the outpouring of lava, with significant flows observed, but it did not produce significant ash plumes or explosive ejecta typical of higher VEI ratings. Overall, the 2011 event was notable for its lava lake activity rather than explosive eruptions.
They are called index fossils.
Mount Kilimanjaro has a Volcanic Explosivity Index (VEI) of 1, indicating that it is classified as a non-explosive volcano. The VEI is a scale that measures the explosiveness of volcanic eruptions, with higher numbers indicating more explosive activity. Kilimanjaro's eruptions have historically been characterized by relatively gentle lava flows rather than violent explosive events. Its last major eruption occurred around 360,000 years ago, and it is primarily known for its stunning landscapes and iconic snow-capped peak rather than explosive volcanic activity.

Hawaiian eruptions are the least severe. It is a 0 on the Volcanic Explosivity Index VEI scale.Strombolian eruptions are relatively mildly explosive 1-2 on the VEI scale.Vulcanian eruptions are 2-3 on the VEI scale.Peléan eruptions are 4-5 on the VEI scale.Plinian eruptions are the most destructive. They are from 6-8 on the VEI scale.http://ete.cet.edu/gcc/?/volcanoes_explosivity/

The 1980 eruption of Mount St. Helens, a stratovolcano located in Washington state, in the United States, was a major volcanic eruption. It rated a 5 on the Volcanic Explosice Index, which rates volcanic eruptions from 1-10.

Here's a start umbers=[True]*5001 index=2 primes=[] while index<5000: multiplier=2 while index*multiplier <= 5000: Numbers[index*multiplier]=False multiplier+=1 index+=1 while Numbers[index]==False and index < 5000: index+=1 for x in range(0,5000): if Numbers[x]==True: primes.append(x) x+=1 print primes
The minimum value of the refractive index is 1, which corresponds to a vacuum. The refractive index of a medium is always greater than or equal to 1.
