It is always a good thing to learn something new. Learning something new that is came out of nowhere and just happened regardless is even better. That's one of such cases.
I was going through the newsletters and newsfeed and one thing came to my attention. There was nothing of interest and then i went to Wikipedia and clicked "Random Article". I've got this thing - Volcanic Explosivity Index.
What it is? It is a logarithmic relative measure scale for volcanic eruptions. It goes from zero to eight. The criteria for assessing Explosivity are:
- Ejecta
- Plume
- Height of eruption
- Length of eruption
The descriptors of the eruptions are rather cool and can be used as a scale for anything.
Here it is:
- 0 - effusive,
- 1 - gentle,
- 2 - explosive,
- 3 - catastrophic,
- 4 - cataclysmic,
- 5 - peroxysmic,
- 6 - colossal,
- 7 - super-colossal,
- 8 - mega-colossal.
Imagine using it to describe an impact of some Mahler performance.
