Disaster prevention suggestions:
1. Emergency preparedness. The family emergency kit should include water (4 liters per person per day), food, flashlights, first aid supplies, and important documents.
2. Develop a family communication plan and agree on a meeting place after the earthquake.
3. Pay attention to building safety. Check if the house meets California seismic standards, reinforce bolts, and reinforce soft layer structures.
High rise buildings should pay attention to furniture fixation to avoid "non structural damage", such as pendant lights falling or bookshelves collapsing.
4. Pay attention to official resources. Real time monitoring: USGS earthquake ground; Register for the San Diego County AlertSan Diego emergency notification system, and San Diego residents can receive alerts several seconds to tens of seconds in advance through the MyShake mobile app.
