Welcoming International Student Visitors to Western University
We are pleased to welcome international student visitors to Western as part of an ongoing CIRCLE project collaboration. These students have joined us from Universidad Tecnológica de La Habana (CUJAE) to participate in academic and research activities on our campus.
During their visit, they will be based in the Department of Engineering. Their presence reflects CIRCLE project commitment to supporting global partnerships and providing meaningful opportunities for academic exchange.
We are excited to have them with us and look forward to the valuable contributions they will bring to the project and our academic community.

Tofino Stands Out for Tsunami Preparedness Despite High Risk
According to Earth sciences professor Katsuichiro Goda, Tofino faces a higher tsunami risk than many areas along B.C.'s coast, yet it demonstrates exceptional preparedness for a community of its size.

Risk-based multi-hazard microzonation for earthquakes and tsunamis
Abstract
A multi-hazard spatial mapping for shaking and tsunami risks is necessary for coastal communities that face imminent dangers from megathrust subduction earthquakes. Conventional single-hazard (seismic or tsunami) mapping methods are not effective in addressing this research gap because the individual hazard effects cannot be combined directly. This study presents a new risk-based multi-hazard microzonation method, which displays relative risks of a representative building asset due to earthquakes and tsunamis within a local community and applies it to the District of Tofino in British Columbia, Canada, which is located in the Cascadia subduction zone. A recently developed catastrophe model is used to generate a comprehensive set of multi-hazard loss data for Tofino by reflecting two local factors, i.e., site amplification proxy for shaking and high-resolution topography for tsunami. The risk-based multi-hazard microzonation maps capture spatially varying loss contributions from shaking and tsunami hazards at different annual probability of exceedance levels. Different visualization approaches can be considered to facilitate the disaster risk management and risk communications with residents and stakeholders.

Quick Loss Estimation Tool (QLET) for Seismic Risk Assessment in Canada
A new peer-reviewed article has been published in GeoHazards titled:
“Rapid Computation of Seismic Loss Curves for Canadian Buildings Using Tail Approximation Method”
Authors: Payam Momeni, Katsuichiro Goda, Navid Sirous, and Sheri Molnar
Traditional seismic risk assessments often require specialized expertise and extensive computational time, making probabilistic seismic risk evaluations less accessible to practitioners and decision-makers. To reduce the barriers related to applications of quantitative seismic risk analysis, this paper develops a Quick Loss Estimation Tool (QLET) designed for rapid seismic risk assessment of Canadian buildings.
By approximating the upper tail of a seismic hazard curve using an extreme value distribution and integrating it with building exposure-vulnerability models, the QLET enables efficient computation of seismic loss curves for individual sites. The tool generates seismic loss exceedance probability curves and financial risk metrics based on Monte Carlo simulations, offering customizable risk assessments for various building types.
The QLET also incorporates regional site proxy models based on average shear-wave velocity in the uppermost 30 m to enhance site-specific hazard characterization, addressing key limitations of global site proxy models and enabling risk-based seismic microzonation. The QLET streamlines hazard, exposure, and vulnerability assessments into a user-friendly tool, facilitating regional-scale risk evaluations within practical timeframes, making it particularly applicable to emergency preparedness, urban planning, and insurance analysis.
QLET is freely available as an open-source repository on GitHub, providing both the MATLAB codes and GUI-based application for users and researchers:
