Earthquake Preparedness Recommendations

  • 🛠️ Recommended actions include securing heavy furniture, identifying safe places to take cover, and having a plan for communication and meeting points.
  • 🎒 Gathering essential supplies like water and emergency kits (go bags) for home, car, and workplace is advised.

What NOT to Do During an Earthquake

  • 🚪 Do not shelter in doorways, as they do not protect from falling or flying objects.
  • 🔥 Do not use matches or lighters near stoves due to potential gas leaks.
