Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

SEISMIC ASSESSMENT OF SUSPENDED CEILING SYSTEMS [PDF]
, 2010 Non-structural components in most types of commercial building represent a major portion of the total cost of the building and, as such, will represent a large portion of the potential losses to owners, occupants, and insurance companies. Non structural

Development of the seismic fragility assessment methodology for seismic isolated NPP structures [PDF]
, 2019 As demonstrated by the 2011 East Japan Great Earthquake, earthquakes are a major risk contributor to nuclear power plants (NPPs). Seismic isolation is one of the most effective alternatives for enhancing the seismic safety of NPPs.
