From the Introduction: "The HayWired Earthquake Scenario--Engineering Implications is the second volume of U.S. Geological Survey (USGS) Scientific Investigations Report (SIR) 2017-5013, which is planned to be published as three volumes. The previous volume of this work (SIR 2017-5013-A-H; Detweiler and Wein, 2017) described a Mw 7.0 mainshock on the Hayward Fault, along with an aftershock sequence and other geologic hazards. This volume (SIR 2017-5013-I-Q) presents engineering impacts that could result from the effects of the HayWired scenario. Together with environmental, social, and economic impacts (including impacts to telecommunications and the internet) that are planned to be described in a third volume, these works describe the HayWired scenario, which was developed by USGS and its partners."
