| Summary: | <p>The earthquake early warning systems (EEWSs) in China
have achieved great progress, with warning alerts being successfully
delivered to the public in some regions. We examined the performance of the
EEWS in China's Sichuan Province during the 2019 Changning earthquake.
Although its technical effectiveness was tested with the first alert
released 10 s after the earthquake, we found that a big gap existed between
the EEWS's message and the public's response. We highlight the importance of
EEWS alert effectiveness and public participation for long-term resiliency,
such as delivering useful alert messages through appropriate communication
channels and training people to understand and properly respond.</p> |
