Origin: Formed within English, by derivation; originally modelled on a German lexical item. Etymons: explosive adj., -ity suffix.

Etymology: < explosive adj. + -ity suffix (compare -ivity suffix), in sense 1 after German Explosivität (1847 or earlier). Compare French explosivité (1861 or earlier).

1. The property of being explosive (explosive adj. 2a); the degree to which something is explosive.

1912 Jrnl. Amer. Chem. Soc. 34 1686 He appears inclined to assume that there was some connection..between the explosivity of the salt and the radioactivity of uranium.

1968 Jrnl. Water Pollution Control Federation 40 1993/2 When the vapors were field tested with a standard explosimeter, an explosivity reading of 70 percent of the lower explosive limit of hexane was registered.

1990 R. King Safety in Process Industries ix. 199 This simple test..has detonated compounds whose explosivity more sophisticated tests have failed to reveal.

2009 R. K. Sinnott & G. Towler Chem. Engin. Design (ed. 5) iv. 166 Always include any compounds that are expected to be present and are known to have significant health, safety or environmental concerns, such as compounds with high toxicity or explosivity.

2. Volcanic activity characterized by the forceful ejection of pyroclastic material; the magnitude of such activity during an eruption or phase of an eruption; the property of erupting in this way.

ΚΠ

1916 Amer. Jrnl. Sci. 192 447 The explosive activity was considerable but not by any means catastrophic, the only truly paroxysmal explosivity having been extremely limited.

1938 Sci. Progress July 100 Explosivity depends on the depth of origin of the magma, since at greater depths magma is able to dissolve more gas.

1959 Bull. U.S. Geol. Surv. No. 1028-N 415 Four historic Alaskan eruptions..provide examples of the range of past explosivity and intensity, no doubt comparable to those of the future.

1982 Jrnl. Geophysical Res. C. 87 1234/1 The volcanic explosivity index (VEI) is a general indicator of the explosive character of an eruption.

2007 B. Riffenburgh Encycl. Antarctica I. 1041/2 The direct measurement of sulphate allows a reliable estimation of the climatic impact of a volcanic eruption, independent of its explosivity.
