Building on Weick's 1993 definition of cosmology episodes, Weick, his colleagues, and other researchers have advanced knowledge of best practices during cosmology episodes at four levels of analysis: (1) catastrophic cosmology episodes, such as the 9/11 terrorist attacks of 2001 and the Haitian earthquake of 2010; (2) disastrous cosmology episodes, such as the 2004 Indian Ocean tsunami and the 2005 Hurricane Katrina; (3) contextualized cosmology episodes occurring within specific domains, such as the 1976 Three Mile Island nuclear system incident and the 1970 Apollo 13 space system incident; and (4) everyday cosmology episodes, such as transition of leaders at the top of an organization and the introduction of new technologies throughout an organization.
