Paleoseismology in Sudbury, Ontario

A paleoseismological investigation was conducted in Sudbury, Ontario, involving geological and geophysical surveys. The project was divided into three phases. The first phase involved geological mapping, where detailed information on seismotectonic setting, historical seismicity, and bedrock and surficial geology of the region were shown. In the second phase, reconnaissance field trips were undertaken to identify potential locations that exhibited evidence of liquefaction from historical earthquakes. The third phase focused on geophysical field surveys, specifically sub-bottom acoustic profiling, carried out on several lakes in the region. The purpose was to gather data about the sediment layers beneath the lakes' bottoms using acoustic waves. The collected data were then interpreted to understand the geological and stratigraphic characteristics of the lake sediments.
