As many as 15 major active faults run underground in Beijing, the capital of China.
One-third or five of these active faults are “strong and active.”
“There is a high risk of a large-scale earthquake in the next 100 years,” it became clear.
Beijing Earthquake Bureau:
The “Earthquake Early Warning System” was scheduled to be completed by 2020, but the plan has been delayed.

China Geological Survey:
Jointly conducted a geological survey centered on Beijing, and published the results in the academic journal “Geophysical Journal”.
According to the report, the number of major active faults in Beijing is 15 which is almost double the number of the previous survey.
“The potential for the Beijing Plain to face geological hazards is closely linked to the activity of active faults,” he said.

Wide range of seismic activity
High magnitude,
Because the epicenter is shallow
It often leads to enormous damage such as death or injury of personnel and loss of property.
Past history:
Historically, there have been about 100 strong earthquakes in China.
Of these, four killed more than 200,000 people at a time (six times worldwide).

Magnitude 5 or higher 20 times a year,
Magnitude 6 and above four times a year,
Magnitude 7 or higher twice every 3 years,
Large earthquakes occur several times a year.
Sichuan Earthquake:
As for the 20th century
Earthquakes account for more than 50% of the death toll from natural disasters in China.
It is the number one cause of all casualties.
A magnitude 8.0 earthquake in Sichuan on May 12, 2008 killed nearly 90,000 people.
