Geoscience BC executive VP Carlos Salas, and lead research Dr. Pat Monahan presented at the PRRD Thursday about their latest Peace Region Project which addresses public concerns relating to seismicity and oil and gas industry activity. This includes northeastern BC, especially in areas close to communities and infrastructure. It will examine how seismic waves from earthquakes can potentially be amplified in specific shallow geological conditions.
The pair updated the directors on seismic ground motion hazard mapping for the area, after an open house hosted Wednesday evening at KPAC.
“We want to understand things better, why are we feelng events lower than 3.0,” said Salas.
We had a kick off meeting at KPAC - where the public could tell where are they feeling these events, and perhaps what is the site class they are on.”
Monahan said any mapping done would be useful for any projects going forward.
“We’re going to map at a finer scale that instead of using existing maps, create and make new maps. We will be looking for more geotechnical data from the PRRD.”
Director Dan Rose said the work being done was key.
“The work they do is so important to help support the science being taken. It is so valuable to us and resource development - it provides unbiased scientific data to make really informed opinions.”
The researchers will collect data from petroleum industry wells, water wells, and geotechnical boreholes to prepare a new geological map at a 1:100,000 scale that will more accurately define the surficial map unit boundaries and reflect the thickness variations in the deposits that are susceptible to amplification.
