| Abstract | Within a catalogue of seismic events, it is necessary to distinguish natural tectonic earthquakes from seismic events due to human activity or other natural processes. This becomes very important when
the data are incorporated into models of seismic hazard, since natural and anthropogenic events follow different recurrence and scaling laws. This document outlines a two-step procedure whereby first, a most likely event type is identified, and
second, confirmation or refutation is sought. The procedure is intended to be compatible with current and past practices at the Canadian Hazards Information Service and the Geological Survey of Canada in assigning event types in the National
Earthquake Database (NEDB). Furthermore, this document presents a new nomenclature and coding system for event types and their certainty, one that is compatible with QuakeML. Detailed classification criteria are given for all common event types; for
rare event types, only definitions and examples are given. |
