Canadian Earthquake Epicenters From Geological Survey Network

250,000 earthquake records from the Geological Survey of Canada's monitoring network. The dataset includes events where parameters like magnitude and depth were recorded, though early entries have blank fields from the network's installation phase. Depths are fixed to integer multiples of 5km based on seismic residuals and crustal structure.

Use Cases

• Analyze spatial clustering of earthquake epicenters to identify active seismic zones across Canada
• Study the relationship between event magnitude and fixed depth values to model crustal stress
• Model the temporal evolution of recorded event counts as the network's station density and magnitude threshold changed
• Filter for larger, potentially damaging earthquakes likely recorded from the network's inception due to their widespread wave propagation

Strengths

• Contains 250,000 located earthquake events
• Managed by the authoritative Geological Survey of Canada's earthquake monitoring network
• Depth values are fixed using a consistent methodology based on lowest obtainable residuals and known crustal structure

Limitations

• Early records contain blank fields where parameters were unknown during network installation
• All depth values are constrained to integer multiples of 5km, which may not reflect true continuous depth
• The magnitude threshold for located events changed over time as more stations were added, affecting completeness for smaller events
