Seismic and Acoustic Waves from a Meteor

On 1 April 1965, at 05:48 U.T., a meteor struck the earth in the Banff-Penticton area of British Columbia, Canada. The meteor was sighted and recorded by seismic and infrasonic equipment. The U. S. Coast and Geodetic Survey analyzed Canadian and United States seismograms from the immediate vicinity. Sufficient acoustic, surface, and body-wave seismic signals were recorded to outline an epicentral area of impact. This assisted the Canadian Government in carrying out an aerial photographic survey and on-site inspection tour. This represents the most geophysical data available on this unique event, and perhaps the best documented within recent historical times.
