|Enhanced Seismic Monitoring Capability|
Digital seismological observation network, a largest earthquake prevention and disaster
preparedness project that has consumed a budget worth RMB 2.28 billion in the country,
has recently passed an approval check. The event marks China's escalated status in
earthquake prevention and disaster preparedness.
Launched in June 2004, the project is made up of 6 components, or three networks and
three systems, including a precursor network, a digital earthquake measuring network, a
digital strong earthquake network, a fault detecting system, an earthquake emergency
commanding system, and an earthquake information system. The implementation of the
project has filled up the blanks in seismic watch, with an enhanced and digitized
observation capability, and a data sharing platform.
According to a briefing, digital process is the core of the project, with a real time data
sharing network for monitoring, prediction, and disaster preparedness. It has greatly
enhanced the density of earthquake watch stations in the country, and optimized their
distributions, with 0.4 precursor earthquake, 0.88 earthquake, and 1.2 strong earthquakes
for per 10,000 square kilometer, 95% of the monitoring equipment being digitized, a
shortened quick report time from 30 minutes to 10 minutes, and an improved lower limit
magnitude from 4.5 to 2.5.
