How is a volcano measured?
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.
What index measures the magnitude of volcanic eruptions?
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).
What is the most common VEI for volcanoes in Hawaii?
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.
What is fossils organisms that lived a short period of time called?
They are called index fossils.
How can you use indirect measurement to calulate the thickness of one index card?
You can use indirect measurement to calculate the thickness of one index card by stacking multiple index cards together and measuring the total thickness, then dividing that measurement by the number of cards in the stack. This will give you an approximation of the thickness of one index card based on the total thickness of the stack.

What are the volcanic eruption types in order from the least destructive to most destructive?
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/

On a scale of 1 to 10 what would the St Helens eruption be?
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.

What is the refractive index of vacuum?
Refractive index of vacuum is 1.
Solution to find 1000th prime number using python?
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
What is cost index?
1$
What is the minimum value of the refractive index?
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.
How many atoms are in a molecule of SO4?
5 atoms 1 atom of S + 4 atoms of O S's index is 1 so only 1 atom (no index is 1) + O's index is 4 so 4 atoms
