EPICentre Seminars - A Decision-Making Methodology for Risk-Informed Earthquake Early Warning
03 March 2021, 12:00 pm–1:00 pm
In this seminar Dr Gemma Cremen discusses a novel end-user-oriented approach for Earthquake Early Warning (EEW) decision-making.
This event is free.

To maximize the potential of earthquake early warning (EEW) as a credible tool for seismic resilience promotion, it should be combined with next-generation decision support tools that use advanced risk-based predictions and account for unavoidable malfunctions of the system (i.e., false alarms) to determine whether or not alerts/ mitigation actions should be triggered.
This presentation will discuss a novel end-user-oriented approach for EEW decision-making that contributes to the required effort. The proposed methodology unifies earthquake-engineering-related performance assessment procedures/metrics (for end-user-focused damage and consequence estimation) with multi-criteria decision-making tools (to consider end-user preferences towards different types of risks).
The benefits of the developed approach will be demonstrated through a series of case studies, using a hypothetical school building.
Please note that the session may be recorded and retained as per UCL’s retention schedule.

About the Speaker
Dr Gemma Cremen
Research Fellow at University College London - EPICentre
Gemma is a Research Fellow at UCL, who specialises in developing statistical tools to support decision-making related to seismic activity and other natural hazards. She is currently working to quantify, model and communicate disaster risk within the GCRF-funded “Tomorrow’s Cities” hub (https://www.tomorrowscities.org/) and is also contributing to the ongoing development of next-generation earthquake early warning systems within the EU-funded “TURNkey” project (https://earthquake-turnkey.eu/).
Prior to joining UCL, Gemma worked at the University of Bristol on improving understanding of the seismic hazard and risk associated with UK shale gas development. She completed her PhD in Earthquake Engineering at Stanford University in 2019.
