Abstract

The seismograms at Some Indian stations appear to indicate opposite sense of the first PKP motions for the Peru-Brazil border earthquake of 19 August 1961. The PKP motions are impulsive and seem to arrive simultaneously on all the components of the records. In order to avoid any doubt about the relation between the trace and ground displacements, seismograms of the same earth- quake from instruments having optico-mechanical registration are also presented.
