🌊 Tsunami Preparedness: React Fast, Stay Safe
💡 Fast Facts That Could Save Your Life
- Tsunamis can arrive minutes after an earthquake, with waves traveling up to 500 mph
- You may only have 10–30 minutes to evacuate—don’t wait for official alerts if you feel strong shaking
- Most tsunami deaths occur within the first wave—but later waves can be just as deadly
- All coastal areas near the ocean, especially after a large offshore or coastal earthquake, are at elevated risk
⚠️ What Makes Tsunamis So Dangerous?
- Little Warning: Earthquake-triggered tsunamis often strike before alerts can be issued
- Multiple Waves: Tsunamis arrive in sets—the second or third wave is often larger than the first
- Inland Flooding: Water can surge miles inland, wiping out roads, bridges, and entire neighborhoods
- Debris + Current Hazards: Floodwaters often carry cars, wood, metal, sewage, and chemical runoff
- Post-Tsunami Hazards: Fires, contamination, electrocution, and displacement are common
🌎 Coastal Earthquakes = Immediate Risk
If you are near the ocean and feel a strong or long-lasting earthquake:
- Do not wait for a tsunami warning
- Immediately move inland and to higher ground (at least 100 ft elevation or 2 miles inland, if possible)
- A tsunami may arrive in under 15 minutes
🎒 Essential Tsunami Gear & Go-Bag Checklist
Have these items pre-packed and ready if you live near the coast:
- Lightweight go-bag stored above ground level
- High-grip shoes or boots (roads may be slick or covered in debris)
- Paper maps with marked evacuation routes
- Headlamp or flashlight (power outages are common)
- Emergency whistle
- Portable water filter and snacks
- N95 mask (for post-disaster air/mold)
- Copies of ID and medication list in a waterproof pouch
- Poncho or emergency blanket for warmth and wind protection
🚨 Evacuation or Shelter?
🏃♂️ Evacuate Immediately If:
- You feel a strong or long earthquake (especially near the coast)
- You hear a tsunami siren, see a rapid water recession, or get an alert
- You’re located on the coast, harbor, or river connected to the ocean
🏠 Shelter Only If:
- You're already inland and on elevated, tsunami-safe ground
- You have no safe evacuation option (in which case, go to the highest possible floor or rooftop)
⏳ How long may you be displaced?
Anywhere from 24 hours to several weeks. Roads, utilities, and infrastructure may take time to restore.
👨👩👧👦 Family Tsunami Safety Tips
- Practice evacuation routes with your family at least twice a year
- Designate a high ground rally point and keep it known to all household members
- Keep a wallet-sized tsunami checklist card in your child’s bag
- If you're near the beach and feel shaking, don’t wait—run uphill or inland immediately
- Pets should be part of your evacuation plan (leash, food, ID tags in the go-bag)
