Preventive measures
Earthquake warning on mobile phones
Suggestions of improvement of preventive/remedial measures
Why the negative impacts caused by the hazard were/were not serious?
124 shelters have been set up in Luding
Some schools hold earthquake drills once a month
click to edit
The school stipulates that earthquake drills should be organized at least once a year
Sichuan Province is included in the seismic fortification zone
Were
Were not
The earthquake has a high magnitude and a shallow source
People have earthquake warnings on their phones and know how to avoid them in advance
Some people hold regular earthquake exercises
The seismic resistance level of buildings in Sichuan is relatively high, making them less prone to collapse

People can hide in shelters
The destruction of traffic roads has hindered the rescue team's operations
The rescue team is well trained and the supply of rescue materials is sufficient
Sichuan is mountainous and prone to landslides
preventive
remedial
Planting more plants on the mountains can prevent soil erosion
Encourage more people to regularly conduct earthquake drills

Power outage leading to loss of contact
Strengthen training for rescue teams
Add more rescue teams
Places where hydropower stations are built should avoid mountains
Increasing the number of personnel involved in road repairs can make rescue operations more convenient
Drainage facilities should be more complete to avoid floods
Increase the seismic resistance level of the building
Reasonably carry out engineering construction in earthquake areas, such as avoiding areas where mudslides and landslides occur as much as possible for railways
