Experience in introduction of an automatic system of earthquake source parameter calculation based on an existing seismic network is described. Open source software products for automatic seismic data processing are reviewed. Methods for real-time waveform stream processing are discussed in detail. Parameters of some subroutines of the system are described. Information flows and data life cycle in the developed automatic system are outlined. Earthquake location errors in the system are analyzed. The detection capability of seismic networks is evaluated. 相似文献

We report determinations of the focal mechanisms for Sakhalin earthquakes during 2006 through 2015 by two different methods: the polarity of first motions using the FOCMEC program and the inversion of waveforms using the ISOLA program. We show that the resulting moment tensor solutions fairly well fit the tectonic crustal stresses for Sakhalin as determined by previous workers. We have examined the component of the moment tensor that involves a linear dipole. This is at its maximum in areas of active mud volcanism and industrial activities in oil-and-gas fields. 相似文献

Features of the new architecture of an automated system for acquisition, storage, and processing of seismic data are considered in detail. The system is based on SEISNET and SEISAN software. Specific technologies, software, and examples of the interconnection of system components are presented. The functionality of the system and the data life cycle are shown. An example of the implementation of the new architecture in the existing seismic monitoring network in the northern part of Sakhalin Island is examined. 相似文献

The key stages of automation of routine earthquake data processing are described. The software, technologies, and equipment are specified. The method for determining earthquake source parameters is considered in details. The experience in the seismological data interpretation taking recent velocity profiles of the region into account is demonstrated and the determination accuracy is justified. The information about the configuration of the local network of seismic stations and the velocity structure of the earth??s crust in the north of Sakhalin Island is presented. 相似文献

An earthquake with the moment magnitude M w ?=?5.8 occurred in the middle part of the Sakhalin Island, Russian Federation, on 14 August 2016, at 11:17 a.m. UTC. The earthquake source was located west of the Central Sakhalin Fault Zone, which is considered to mark the boundary between the Okhotsk and Eurasian (Amurian) plates. Moment tensor solution of the mainshock as well as the configuration of aftershock cloud suggests that the earthquake was caused by slip on a SW-dipping reverse fault. For the first time for Sakhalin, we have got the felt reports unified in accordance with DYFI. We also analyzed observed PGA values and, based on them, produced shaking maps. 相似文献
