英语词汇“volcanic explosivity index”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

volcanic explosivity index n. a number on a logarithmic scale representing the estimated magnitude and violence of a volcanic eruption; abbreviated VEI.The index is based on the volume of material ejected, height of eruption clouds, duration of the eruption, and other factors.

1981 T. Simkin et al. Volcanoes of World 20/2 Newhall and Self (in press) have integrated quantitative data with the subjective descriptions of observers to assign a Volcanic Explosivity Index (VEI) to individual eruptions.

1982 C. G. Newhall & S. Self in Jrnl. Geophysical Res. 87 1231 A composite estimate of the magnitude of past explosive eruptions, termed the Volcanic Explosivity Index (VEI), is proposed.

1994 Mount Rainier (Nat. Res. Council) i. 2 Mount Rainier is capable of eruptions of small to very large magnitude, as measured by the Volcanic Explosivity Index of 4 to 5 that has been tentatively assigned to the explosive eruption that occurred between 30,000 and 100,000 years ago.

2010 Daily Tel. 16 Apr. 23/1 Scientists rank volcanoes according to how explosive they are, using the volcanic explosivity index (VEI), which goes from zero to eight.
