Earthquake early warning is an effective tool to reduce earthquake hazards and losses, but many places can not afford the luxury to have a dense seismic network. MyShake is a project aiming to build a global smartphone seismic network and bring the earthquake early warning to places where there is no or few seismic stations but dense population clusters. With an on phone algorithm to distinguish the human and earthquake movement, everyone's smartphone can be used as a portable seismometer to detect earthquakes. In addition, with the aggregation of a network of phones that detect the earthquake, we can locate, estiamte the magnitude and origin time of the earthquake and issue an earthquake early warning message to the public using only data from smartphones. In this presentation, I will talk about the recent updates of our effort to issue warnings with the smartphone network. Real-world cases, as well as simulated events, will be shown to prove the effectiveness of this approach if we have a large number of users to run MyShake application on their phones. With the practice and test in the first three years after MyShake release, we believe issue earthquake early warning through the smartphone network is feasible.
