During the "15th Five-Year Plan" period, my country's earthquake monitoring capabilities will reach level 1.0-2.5

Reporters learned from the press conference on the theme of "Getting Started with the 15th Five-Year Plan" held by the State Council Information Office today (21st) that in order to further improve earthquake monitoring, forecasting and early warning capabilities, our country will improve the three-dimensional monitoring network.

Construct intensive observation networks for deformation, fluid, electromagnetic and other geophysics in key areas;

Construct deep well observation stations in Beijing-Tianjin-Hebei and other regions to obtain scientific data with higher precision and higher spatial and temporal resolution, and improve the ability to capture earthquake precursor information;

Construct marine seismic observation stations in coastal waters;

Seismic monitoring stations will be densely deployed in the southwest, northwest and other regions to expand the seismic monitoring capabilities and scope of sea areas and western regions.

Integrate various dedicated seismic station networks and integrate them into the national station network system to achieve my country's earthquake monitoring capabilities to reach level 1.0-2.5.

The smaller the value of the monitoring capability level, the

The stronger the monitoring ability

In the work of earthquake prevention and disaster reduction, earthquake monitoring capability is a core indicator. It measures the smallest earthquake that can be accurately recorded by the seismic network in a region. The smaller the value of the monitoring capability level, the stronger the monitoring capability.

How many categories can earthquakes be divided into according to their magnitude?

Earthquakes are roughly classified according to magnitude as follows:

Weak earthquake: The magnitude is less than 3. If the source of the earthquake is not very shallow, it is generally difficult for people to detect this kind of earthquake.

Felt earthquakes: magnitude greater than or equal to 3 and less than or equal to 4.5. Such earthquakes can be felt but generally do not cause damage.

Moderately strong earthquakes: earthquakes with magnitudes greater than 4.5 and less than 6. They are earthquakes that can cause damage or destruction. However, the severity of the damage is also related to various factors such as the focal depth and epicenter distance.

Strong earthquake: An earthquake with a magnitude greater than or equal to 6, which can cause serious damage. Among them, those with magnitude greater than or equal to magnitude 8 are also called giant earthquakes.
