What changed
China plans to build an integrated earthquake monitoring, forecasting and early-warning system covering space, air, land and sea during the 15th Five-Year Plan period. The China Earthquake Administration will expand marine observation stations in coastal waters, add monitoring stations in western regions, pursue AI-assisted forecasting, and maintain second-level warnings.
The programme also targets monitoring capability for earthquakes between magnitude 1.0 and 2.5, rapid intensity reporting, and a new national seismic zoning standard. China says it will continue strengthening nationwide protection against magnitude-6 earthquakes.
Why it matters
This is a shift from a network of ground stations toward a wider sensing system. Coastal waters and western China are specifically identified for stronger coverage, while separate earthquake-monitoring networks are to be combined into a national system.
The practical goal is earlier and more useful information: warnings measured in seconds, faster estimates of shaking intensity, and forecasts that combine physical models with artificial intelligence. That could give authorities and infrastructure operators more time to respond before strong shaking arrives.
The plan also reaches beyond warning technology. A revised national seismic zoning map would set earthquake-resistance requirements for ordinary construction and fill a gap in offshore seismic zoning. In other words, the programme is meant to influence both the alarm that arrives before an earthquake and the buildings expected to withstand it.
The ambition is clear, but the announcement does not yet specify funding, interim milestones, coverage targets or exact implementation dates within the five-year period. Its significance will depend on how quickly the expanded network becomes operational and how reliably its forecasts and warnings perform.
