A detailed reflection–refraction experiment was conducted near Yellowknife, Northwest Territories, in 1969. Over 3000 seismograms were recorded along two profiles with a geophone separation of 250 m. The high quality, quantity and unexpectedly high

A crustal refraction experiment was carried out around Yellowknife, Northwest Territories, in 1966. The pattern of shots and stations was designed for time-term interpretation over a wide area, traversed by a more detailed line of interspersed shots

Long-range seismic observations at the standard Canadian seismic stations, from chemical explosions in Hudson Bay and Lake Superior, are used to derive a P-wave velocity structure for the upper mantle. The coordinates of observed cusps are used to de

The stress field in the vicinity of a body of fluid of simple geometry contained within a non-homogeneously stressed solid has been calculated and the result applied to the case of a magma body within a region of the crust subject to triaxial stresse

During the spring of 1967, a seismic refraction experiment was conducted from the SW tip of Prince Patrick Island in the Queen Elizabeth Islands of Arctic Canada to a point mid-way down the continental slope, some 220 km from the coast.It was found t

A method is described for calibrating Willmore seismographs. It could be applied to any other electromagnetic seismograph having a galvanometer period substantially shorter than the seismometer period. The method is rapid and involves very little equ

A frequency selective amplifier has been developed to increase the useful sensitivity of short period electromagnetic seismographs to near earthquakes. The result has been to reduce the magnitude of the smallest earthquake detectable by about two uni
