Abstract
This paper discusses the basic principles of recording processes occurring in the Earth crust during the occurrence and development of catastrophic phenomena using an earthquake as an example, allowing one to determine the coordinates of its source and epicenter. The paper presents the basic approaches to creating the laser interferometric seismoacoustic observatory (LISO) designed to monitor continental-scale seismic events. The paper presents the instrumentations (laser and optical strainmeters, accelerometers, hydrophones) developed and used at the Institute of Automation and Control Processes, Far Eastern Branch of the Russian Academy of Sciences, the V.I.Il’ychev Pacific Oceanological Institute, Far Eastern Branch of the Russian Academy of Sciences, and the Schmidt Institute of Physics of the Earth, Russian Academy of Sciences, intended for use in the observatory being created.
