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

click to edit

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

click to edit

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
