Find the original Canadian event record
Earthquakes Canada, operated by Natural Resources Canada, publishes recent earthquake information and links to regional views. Start with an event's origin time, estimated location, depth and magnitude. The origin time is not the time a map was last loaded. If two services show nearby dots, compare the times and event details before assuming there were two earthquakes.
Its National Earthquake Database cautions that recent information can be preliminary, incomplete and revised. A later magnitude or location can differ from an early bulletin without implying a new event. Cite the provider and time when sharing a number, so someone else can check whether the estimate changed.
Separate magnitude from local effects
Magnitude describes event size; felt intensity describes effects at a location. People in different communities may experience the same earthquake differently because of distance, ground conditions and buildings. The magnitude and intensity guide explains why one figure beside a marker cannot be converted into a building-damage estimate. An epicentre is an estimated point, not a boundary around all shaking.
Felt reports can help describe what people experienced, but the number of reports also depends on population and participation. The absence of reports from a place is not proof that no one felt shaking. Instrumental event parameters and eyewitness observations are related but distinct evidence.
Compare maps without overreading them
Open the PocketWorld earthquake overview and inspect the source and freshness on the selected record. For a Canadian event, follow the Natural Resources Canada record and its regional context. The Canadian monitoring and data-products page describes the national network and catalogues. A map showing only recent events has a different time window from a long historical database, so dot density alone does not describe long-term hazard.
When another agency publishes a value, compare origin time, approximate location and magnitude type before quoting a difference. A revised catalogue or retained PocketWorld snapshot can make an older screenshot appear inconsistent with today's page. Identify the source and retrieval time rather than treating the newest-looking map as automatically complete. PocketWorld is not an earthquake prediction or emergency warning service; follow local authorities for current safety instructions.
Canadian regional catalogues can emphasise different geographic areas and reporting thresholds. A small offshore event may be present in one time-window view yet absent from a summary of significant events. Choose the catalogue that matches the question, and keep its magnitude threshold and date range visible in any comparison.
