Here are some ways to earthquake-proof your house:

1. Strengthen the foundation: The foundation of your house needs to be strong enough to withstand an earthquake. You can reinforce it by adding steel bars or using concrete that's reinforced with steel.

2. Secure heavy furniture and appliances: Heavy furniture and appliances can topple over during an earthquake and cause damage. Make sure they are anchored or secured to the wall.

3. Install earthquake-resistant windows and doors: Windows and doors that are not designed to withstand an earthquake can shatter and cause injuries. You can install tempered glass, which is less likely to break, or use shatter-resistant film to strengthen existing windows.

4. Brace chimneys and water heaters: Chimneys and water heaters can topple over and cause fires during an earthquake. You can install metal straps or braces to keep them in place.

5. Bolt the house to the foundation: Bolting the house to the foundation can prevent it from sliding off during an earthquake. You can hire a contractor to do this for you.

6. Check for structural weaknesses: Hire a professional to inspect your house for any structural weaknesses that need to be addressed.

7. Prepare an emergency kit: In case of an earthquake, it's important to have an emergency kit that includes food, water, medication, and other supplies. Keep it in a place where it's easily accessible.

Remember, no home can be 100% earthquake-proof, but taking these steps can significantly reduce the risk of damage or injury during an earthquake.
