USGS Shakemap/ShakeCast and National Seismic Hazard Model Workshop for Lifeline Systems

People are encouraged to attend the USGS-1 session and the USGS-2 session, but registering for this workshop does not require attendance to both sessions. 

Limited Seating. This event requires an additional ticket. You can reserve your seat by adding the extra ticket during the registration process. The tickets are free (no charge).

ShakeMap is U.S. Geological Survey (USGS) premier tool for rapidly mapping out the distribution and intensity of shaking immediately after earthquakes. The same tools use mapping out shaking based on ground shaking observations are also widely used for planning in the form of ShakeMap scenarios. ShakeCast® is a (USGS) software application that automatically retrieves ShakeMap shaking estimates and performs analyses using fragility functions for buildings and lifelines. The ShakeCast system aims to identify which facilities or lifeline segments are most likely impacted by an earthquake—and thus which ones should be prioritized for inspection and response—and sends notifications to responders in the minutes after an event. By focusing inspection efforts on the most damage-susceptible facilities in the severely shaken areas, ShakeCast can reduce critical lifeline inspection prioritization and response time in the aftermath of a significant earthquake. Overviews and technical specifications of the ShakeMap and ShakeCast software have been presented at earlier conferences; we will describe only significant updates. Rather, we focus on uses and users and their response protocols to provide further insight into the use of the ShakeMap/ShakeCast combination. We focus on users responsible for monitoring and response for lifeline infrastructure, and we emphasize inventory, fragility, and notification issues pertinent to the lifeline engineering audience.

The U.S. Geological Survey (USGS) National Seismic Hazard Model (NSHM) is used for a broad array of earthquake risk mitigation applications, such as construction codes and insurance. To facilitate these uses, but also to motivate improvements and provide feedback, USGS civil engineers (both structural and geotechnical) liaise with numerous NSHM stakeholders, such as the Building Seismic Safety Council (BSSC), the American Association of State Highway and Transportation Officials (AASHTO), and the American Railway Engineering and Maintenance-of-Way Association (AREMA). Recently, the USGS was approached by developers of an American Society of Civil Engineers (ASCE) manual of practice for seismic design of buried water and wastewater pipelines. As a result, the USGS is adding peak ground velocities to the outputs of its NSHM. The purpose of this workshop session is to engage additional lifelines users of the USGS NSHM. Discussion topics will include additional NSHM use cases, such as assessing the seismic risk to pipelines and soil-structure interaction, and additional NSHM products, such as alternative ground-motion intensity measures for ground failure assessments.
