Editing Nuclear weapons testing (section)

===Salvo tests===
Another way to classify nuclear tests is by the number of explosions that constitute the test.  The treaty definition of a salvo test is:

<blockquote>In conformity with treaties between the United States and the Soviet Union, a salvo is defined, for multiple explosions for peaceful purposes, as two or more separate explosions where a period of time between successive individual explosions does not exceed 5 seconds and where the burial points of all explosive devices can be connected by segments of straight lines, each of them connecting two burial points, and the total length does not exceed 40 kilometers. For nuclear weapon tests, a salvo is defined as two or more underground nuclear explosions conducted at a test site within an area delineated by a circle having a diameter of two kilometers and conducted within a total period of time of 0.1 seconds.<ref>{{cite web|title=Worldwide Nuclear Explosions| first1=Xiaoping| last1=Yang| first2=Robert| last2=North |first3=Carl| last3=Romney| first4=Paul R.| last4=Richards| url=http://www.ldeo.columbia.edu/~richards/my_papers/WW_nuclear_tests_IASPEI_HB.pdf}}</ref></blockquote>

The USSR has exploded up to eight devices in a single salvo test; Pakistan's second and last official test exploded four different devices.  Almost all lists in the literature are lists of tests; in the lists in Wikipedia (for example, ''[[Operation Cresset]]'' has separate items for ''Cremino'' and ''Caerphilly'', which together constitute a single test), the lists are of explosions.
