GRiD W-phase MT: Realtime Earthquake Analysis System for Large Earthquake and Tsunami Earthquake

我们开发并实现了一个新的基于网格的地震分析系统，可以连续监测区域和全球宽带地震仪记录的长周期地震波场(W相)。这一新的分析系统可以自动同时确定大地震和海啸地震的发源时间、地点和矩张量，区域性地震在6分钟内，全球地震在15分钟内。

We have developed and implemented a new grid-based earthquake analysis system that continuously monitors long-period seismic wave filed (W-phase) recorded by regional and global broadband seismometers. This new analysis system automatically and simultaneously determines the origin time, location and moment tensor of large seismic events and tsunami earthquakes within 6 min for regional events and 15 min for global ones.
