Аннотация:This paper presents the basic principles of recording processes occurring in the Earth’s crust during the occurrence and development of catastrophic phenomena using an earthquake as an example; these principles allow one to determine the coordinates of the source and epicenter. Basic approaches are revealed to creating a laser interferometric seismoacoustic observatory (LISO) designed to monitor continental-scale seismic events. This study also describes the instrumental equipment (laser and optical strainmeters, accelerometers, and hydrophones) developed and used at the Institute of Automation and Control Processes FEB RAS, the V.I. Il’ichev Pacific Oceanological Institute FEB RAS, and the O.Yu. Schmidt Institute of Physics of the Earth RAS; this equipment is intended for use in the LISO.
