Objectif(s): To improve understanding of regional active tectonics and geological history of North America through incorporating two existing seismic stations that automatically detect and report both earthquakes occurring locally and globally.

Description du projet: This licence has been issued for the scientific research application No.4686. The objective is to incorporate two existing seismic stations installed and currently operated by the Incorporated Research Institutions for Seismology (IRIS) into the Canadian National Seismograph Network (CNSN), where NRCan, through the Canadian Hazard Information Service (CHIS), would operate and maintain the station for long-term (decadal) hazard monitoring in northern Canada. The stations, A36M in Sachs Harbour and C36M in Paulatuk, would support NRCan’s capability to automatically detect and report both earthquakes occurring locally and globally (from larger magnitude events). The stations were initially installed by IRIS with the main objective being to improve understanding of regional active tectonics and geological history of North America. NRCan is a department of the Government of Canada and will be directly responsible for day-to-day operation and maintenance of the seismic stations which are part of this project. Local agents will conduct site visits on behalf of NRCan if required for maintaining continuous data collection. Each site visit will involve inspecting all components of the seismic stations and replacing/repairing equipment or station components as required. Field parties will typically be 1-2 people with typically only one day required on site. As stations are already established and NRCan is looking to adopt operations of the stations, the communities of Sachs Harbour and Paulatuk were contacted to seek continued support for long term operations. If communities wish to have periodic updates on operations of the station, such information can be provided at any time. Each community has or can be provided with the web portal link to obtain data from the stations if desirable. Community consultation for these stations was conducted by IRIS as part of the original installation process, including local Hunter and Trapper associations. The fieldwork for this study will be conducted from March 8, 2022 to December 31, 2022.
