Review of earthquake early warning from an engineering perspective
Abstract
After the concept of earthquake early warning (EEW) first appeared in the 1980s, we now have officially working EEW systems around the world,
such as, Japan, Taiwan, Mexico, USA, Italy, and so on.
The algorithms of EEW have evolved to a large variety, including both on-site, regional and some hybrid methods.
The underlying seismic model ranges from simple point-source ground motion prediction equations to sophisticated finite fault prediction models.
Recently, researchers have also proposed to develop real-time GPS based EEW and purely data-driven seismic intensity prediction models.
Besides the scientific advances, engineering applications of EEW have became another important research topic. In this talk,
I will briefly go through all the topics above in a practical implementation point of view, and highlight some important challenge of EEW.
