摘要
介绍由广东省地震局开发的南海地震监测与海啸数值模拟平台,该平台主要由两部分组成:一是基于国家地震自动速报备份系统的南海地震实时监测平台,全天候实时监测南海及其周边地区进行地震自动速报,如果震级达到6级以上,平台发出声音报警,并预留短信接口,可发布海啸预警信息;二是基于COMCOT模式的南海地震海啸数值模拟平台,根据地震三要素、震源参数、断层参数等,进行数值模拟海啸传播过程,计算海啸到达海岸线的时间和浪高,获得海啸传播时程和破坏程度,用于预判发布海啸预警信息。这两者之间关系密切,缺一不可,先有地震,后才引发海啸,而海啸预警才是最终目的。
This paper presents a detailed introduction to the South China Sea earthquake monitor and tsunami numerical simulation platforms developed by Guangdong Earthquake Agency. The platform mainly consists of two parts： the South China Sea earthquake real-time monitoring platform based on the national automatic earthquake location system, obtains the earthquake quick report automatic real-time monitoring of the South China Sea andits surrounding areas, and gives an sound alarm if the magnitude reached 6 above, meanwhile, with setting aside the phone message interface, it can be issued a tsunami warning information; based on COMCOT mode and according to the earthquake three elements, source parameters, and fault parameters, the South China Sea tsunami numerical simulation platform can calculate the numerical simulation of tsunami propagation process,and obtains the tsunami arrival time, wave height of the coastline, the tsunami propagation process and the damage for pre judgment issued a tsunami warning information. The relationship between two platforms above are indispensable, the earthquake first, and then a tsunami, and the tsunami warning is the ultimate goal.
