Strong motion seismology
Abstract
Strong motion accelerographs and data processing systems for the measurement of strong ground motion of damaging earthquakes are
described with some comments on future developments. Some information
is given on the earthquakes and instrumentation sites for which
important records have been obtained. Studies of the areal distribution
of ground motions during earthquakes are discussed in terms of transmission path effects. Some speculations are advanced concerning the establishment of limiting values of earthquake ground motions.
