Publications A national seismic risk model for Canada: Methodology and scientific basis Share Facebook LinkedIn Download 2023 | Peer-reviewed Canada is exposed to rare but potentially destructive earthquakes that threaten densely settled metropolitan centers in many parts of the country. To assess the impacts and consequences of future natural-hazard events and help advance policy goals and objectives of the Sendai Framework for Disaster Risk Reduction, Natural Resources Canada, through a collaborative partnership with the Global Earthquake Model Foundation, produced a national seismic risk model. Developing this model has required the creation of a national exposure inventory, Canadian-specific fragility and vulnerability curves, and significant simplification of the Canadian Seismic Hazard Model which forms the basis for the design seismic hazard values of the National Building Code of Canada. Using the Global Earthquake Model Foundation’s OpenQuake Engine, probabilistic stochastic risk modeling is completed under baseline and simulated retrofit conditions to assess seismic risk at the neighborhood level for all settled areas in Canada. Output risk metrics include the expected immediate physical impacts of earthquake events such as building damage, casualties, and direct economic losses. This article documents the technical details of the modeling approach including a description of novel data sets in use, a summary of the extensive sensitivity testing undertaken, and characterization of quality control implemented in the absence of usable validating earthquake loss data. The results from this model, such as loss exceedance curves and annual average losses, provide an open, accessible and quantitative base of evidence for decision-making at local, regional, and national levels. As a large country with a complex seismic hazard model and dispersed populations, this Canadian study is unique. However, the challenges faced and solutions offered are likely to be of interest to other nations pursuing similar programs.

Post Event List PURPOSE The purpose of this page is to provide GEM website visitors, researchers, loss modellers, and emergency and disaster risk reduction professionals with specific downloadable information related to red alert events based on USGS PAGER alerts. GEM promotes the sharing of seismic hazard and risk information with a wide range of stakeholders to enhance understanding of damaging earthquake events. This initiative aims not only to give an overview of the models, data and publications available in areas recently impacted by earthquakes, but also hopes to serve as a resource that can inform future risk reduction strategies. The information provided is intended solely for situational awareness purposes and is not aimed towards driving an official emergency response. Please contact your local authorities for further assistance related to official emergency response services and support. 31st August 2025 M6.0 Afghanistan On 31 August 2025, at 23:47 AFT (19:17 UTC), a Mw 6.0 earthquake struck Kunar Province in eastern Afghanistan, near the border with Pakistan (source: https://en.wikipedia.org/wiki/2025_Afghanistan_earthquake).

Back to Bangladesh Outcomes Bangladesh Population and Building Exposure Exposure models play a critical role in seismic risk assessment by quantifying the potential exposure of buildings and infrastructure to earthquake hazards. These models are structured databases that catalogue the characteristics of buildings within a specific geographic area, including their location, construction material, age, occupancy type, and structural design. The depth and accuracy of this data directly influence the effectiveness of the seismic risk evaluations, as they allow for a detailed understanding of how different structures are likely to perform during an earthquake.

News GEM Provides Impact Estimates for Russia, Afghanistan, and Philippine Earthquakes By: Oct 6, 2025 Jul 29, 2025 Share Facebook LinkedIn As part of its role in the ARISTOTLE-ENHSP , the Global Earthquake Model (GEM) Foundation provided rapid impact analyses to the European Research Coordination Centre following three recent earthquakes: the magnitude 8.8 earthquake in Russia’s Kamchatka Peninsula on 29 July 2025, the magnitude 6.0 earthquake in Afghanistan’s Kunar and Nangarhar provinces on 31 August 2025, and the magnitude 6.9 earthquake in the Philippines’ Cebu province on 30 September 2025. Assessing the Kamchatka Earthquake The Kamchatka event was classified as a Red alert for economic losses by the USGS PAGER system, thus triggering GEM’s post-event protocol. GEM scientists used the global hazard and risk models in combination with USGS ShakeMap products to generate impact estimates. While the earthquake was very large, evidence suggested lower-than-expected ground shaking, underscoring the challenge of constrained data in remote regions. GEM’s analyses explored different assumptions for ground motion behaviour, providing ranges of possible impacts to inform ongoing evaluations. Supporting Decision-Making in Afghanistan The Afghan earthquake was also classified as a Red alert for fatalities by the USGS PAGER system. GEM used the epicentre from the European-Mediterranean Seismological Centre (EMSC), combined with a rupture generated using its Global EarthquakE ScEnarios (GEESE) algorithm and regional hazard models, to estimate the likely range of consequences. Outputs shared with the European Commission’s Joint Research Centre (JRC) supported satellite mapping operations. In one case, GEM’s estimates confirmed that the most affected areas had been correctly prioritised for imaging, despite damage being difficult to detect from satellite data. This provided responders with confidence in their initial assessments. Delivering Rapid Analysis in the Philippines For the 30 September earthquake in Cebu, GEM applied its oq-impact tool to generate impact estimates for fatalities, injuries, displaced population, economic losses, and building damage. Maps of expected building loss, fatalities, and homelessness were shared with the Philippine Institute of Volcanology and Seismology (PHIVOLCS) to complement national monitoring efforts. These analyses are based on the USGS rupture, GEM’s global ground motion models, and exposure and vulnerability models for the Philippines providing a first-order estimate of expected impacts while more detailed local data are being gathered. Bridging Science and Response Feedback from partners, including JRC, emphasised the value of GEM’s modelling in the immediate aftermath of earthquakes. By providing independent, model-based estimates, GEM helps humanitarian agencies and national authorities allocate resources more confidently, especially when on-the-ground information is scarce or satellite information is unreliable. Towards Greater Collaboration While GEM is not an operational emergency-response organisation, its role as an information provider helps humanitarian agencies, governments, and international partners respond more effectively to disasters. The recent events in Russia, Afghanistan and the Philippines highlight how scientific models can complement field data and satellite imagery in shaping rapid response. GEM continues to encourage open collaboration and data sharing with partners worldwide, recognising that bridging the gap between science and action is essential for strengthening earthquake resilience – and disaster resilience more broadly – across the globe.
